Abstract

Purpose - The effect of cryogenic heat treatment on the mechanical properties of different materials has been frequently investigated by researchers in recent years. The purpose of this paper is to investigate wear behaviour of monolayer, multilayer and nanocomposite coatings after cryogenic heat treatment. It is a first in its field in terms of both the heat treatment used and the coatings examined.Design/methodology/approach - The aCN/TiAlN, TiAlN and ncTiAlSiN hard coatings deposited on the AISI D2 steel substrate were subjected to cryogenic heat treatment at -145(o)C and -196(o)C for 24 h and then tempered at 200(o)C for 2 h. Then, the samples were subjected to wear tests of 5, 10 and 15 N three different load values. The wear mechanisms occurring on the wear surfaces were determined by scanning electron microscope supported by EDS.Findings - Oxidation, fatigue and delamination wear mechanisms were realized on the surfaces of the samples subjected to dry sliding wear test. The wear resistance of S1 increased with cryogenic heat treatment. According to the wear test results of the untreated samples, it was found that the samples with lower hardness than the others had higher wear resistance. The wear resistance of S1 and S2 samples was increased by cryogenic heat treatment. The best wear resistance in all parameters was obtained by S1. Oxidation in the S1 was found to have a positive effect on wear resistance. According to EDS results after wear of S2, chromium-rich layer was found on the surface of the material. It is understood that cryogenic heat treatment causes carbide precipitation in the inner structure of the substrate material.Originality/value - The effect of cryogenic heat treatment on the mechanical properties of different materials has been frequently investigated by researchers in recent years. In this study, wear behaviour of monolayer, multilayer and nanocomposite coatings after cryogenic heat treatment was investigated. It is a first in its field in terms of both the heat treatment used and the coatings examined.

Answer 1 Thank you very much for your constructive comments. All SEM photographs of the worn surfaces obtained as a result of the wear test applied at 15 N were added and the wear mechanisms were examined. SEM photographs of wear marks applied on other loads have not been added due to the word limit for the journal. Comment 2
    2. Maybe add a few more references? Answer 2 Several new references have been added. Comment 3 Which method did you use to measure the mass/volume of the worn material? Answer 3 Thank you very much for your constructive comments. A photograph of the device where the wear volume measurement is performed has been added.

    I would like to appreciate the worthwhile comments you have given me and thank you for your time given for my paper. The responds to the comments from Reviewer #2 are listed below. I will be glad if you could review the revised paper with the answers. All revised and additional parts in accordance with the reviewers’ comments were written as red color text in the manuscript. Comment 1 In Abstract, include brief introduction of cryogenics and cryogenic treatment. Avoid the terminology ' cryogenic heat treatment' and change to cryogenic treatment. Cryogenics means icy cold below 123K and nothing to with heat. Answer 1 Attention was paid to the terminology and necessary arrangements were made. Comment 2 2. Expansions of aCN, TiAN, etc should be clearly mentioned in the abstract like Amorphous carbon Nitride, Titanium Aluminum Nitride Coating ,etc. Answer 2 Thank you very much for your constructive comments. Explanations of all abbreviations have been added. Comment 3 3.In the subheading " Originality/value", replace 'was' by 'were'. Answer 3 The grammar error has been corrected. Comment 4 4. Try to modify first paragraph of introduction, Change ' have been worn out' to 'wear'. What does the word mechanical effects mean? Answer 4 The first paragraph in the introduction has been changed. Comment 5 5. Table 1 and 2 have to be interchanged. Please look into this matter. Sample 1 and 2 to interchange in order of type of coatings. Answer 5 Table 1 has been removed. The explanations in Table 2 have been expanded. Comment 6 6.What is PVD system? Explain Answer 6 Thank you very much for your constructive comments. PVD abbreviation is explained. Detailed explanation could not be added due to word limitation. Comment 7 7. How did you carryout cryo treatment and tempering process ? Furnish relevent details with pictures/figures since this process is the prime focus of the paper . Answer 7 Thank you very much for your constructive comments. Photo and system properties of the system where cryogenic process is applied are added. Comment 8 8. Point 2.3, wear testing change 'was' to 'were'. sliding distance of 60m ? To mention with figure or photo of wear test apparatus, since the results of this experiment are conclusive for the objective of the paper.
    Answer 8 Thank you very much for your constructive comments. The grammar error has been corrected. “The dry sliding wear test was applied to the samples with sliding velocity 5 cm/s for a sliding distance of 60 meters” sentence has been added. A photo of the "Ball-on-disk Tirbometer" used in the wear tests has been added. Comment 9 9. Make it a point to express the terms in expanded form initially e.g. Scanning Electron Microscope (SEM). The usage of SEM is quite acceptable in the matter being covered later. Answer 9 Thank you very much for your constructive comment. A description of the SEM abbreviation has been added. Comment 10 10. Conclusions: Replace '3' by 'three' Answer 10 Thank you very much for your constructive comment. The error has been corrected.

    3. Which method did you use to measure the mass/volume of the worn material?

    Additional Questions: Originality: Does the paper contain new and significant information adequate to justify publication?: Yes

    Relationship to Literature: Does the paper demonstrate an adequate understanding of the relevant literature in the field and cite an appropriate range of literature sources? Is any signficant work ignored?: It should be expanded with several more references.

    Methodology: Is the paper's argument built on an appropriate base of theory, concepts, or other ideas? Has the research or equivalent intellectual work on which the paper is based been well designed? Are the methods employed appropriate?: Yes

    Results: Are results presented clearly and analysed appropriately? Do the conclusions adequately tie together the other elements of the paper?: Partially

    Practicality and/or Research implications: Does the paper identify clearly any implications for practice and/or further research? Are these implications consistent withthe findings and conclusions of the paper?: Yes

    Quality of Communication: Does the paper clearly express its case, measured against the technical language of the field and the expected knowledge of the journal's readership? Has attention been paid to the clarity of expression and readability, such as sentence structure, jargon use, acronyms, etc.: Yes

    Reproducible Research: If appropriate, is sufficient information, potentially including data and software, provided to reproduce the results and are the corresponding datasets formally cited?:

    Reviewer: 2

    Recommendation: Minor Revision

    Comments: The paper definitely has substance and quality but lacks skilled presentation. There are mismatches, grammatical errors,etc. Please modify as per instructions as under: 1.In Abstract , include brief introduction of cryogenics and cryogenic treatment.Avoid the terminology ' cryogenic heat treatment' and change to cryogenic treatment. Cryogenics means icy cold below 123K and nothing to with heat.

    2.Expansions of aCN, TiAN,etc should be clearly mentioned in the abstract like Amorphous carbon Nitride,Titanium Aluminium Nitride Coating,etc.

    3.In the subheading " Originality/value", replace 'was' by 'were'.

    4.Try to modify first paragraph of introduction, Change ' have been worn out' to 'wear'. What does the word mechanical effects mean?

    5.Table 1 and 2 have to be interchanged. Please look into this matter. Sample 1 and 2 to interchange in order of type of coatings.

    6.What is PVD system? Explain

    1. How did you carryout cryotreatment and tempering process ? Furnish relevent details with pictures/figures since this process is the prime focus of the paper .

    8.Point 2.3, wear testing change 'was' to 'were'. sliding distance of 60m ? To mention with figure or photo of wear test apparatus, since the results of this experiment are conclusive for the objective of the paper.

    9.Make it a point to express the terms in expanded form initially e.g. Scanning Electron MIcroscope (SEM). The usage of SEM is quite acceptable in the matter being covered later.

    1. Conclusions : Replace '3' by 'three'

    If these changes are incorporated, the paper can be recommended for publication

    Please go through the entire paper paying attention to all the details. You might come out with your own modifications. Please include them.

    All the best !

    Quality of Communication: Does the paper clearly express its case, measured against the technical language of the field and the expected knowledge of the journal's readership? Has attention been paid to the clarity of expression and readability, such as sentence structure, jargon use, acronyms, etc.: I appreciate the attempt of the author to study the effects of cryotreatment on wear properties of selected coatings.

    However, the paper lacks the presentation skills with regard to writeup on technical matters. Many of the terminologies have been quoted assuming the reader is well versed with them e.g PVD system, loads of 5-10-15 N,ncTiAlN,etc

    I have enlisted them separately in "comments to Author".

    He has to go through them systematically, make changes and resend so that I will be satisfied to recommend for publication.

    Reproducible Research: If appropriate, is sufficient information, potentially including data and software, provided to reproduce the results and are the corresponding datasets formally cited?: Yes

    The research you presented is very interesting but i would like to give a few suggestions:

    1. Why there are SEM micrographs only for one sample when you tested materials at 6 different conditions? Can you provide pictures for all samples and then compare them?

    2. Maybe add a few more references?

    3. Which method did you use to measure the mass/volume of the worn material?
