The paper studies the possibility of solving a multicriteria problem of comparative wear resistance assessment of nitride coatings (Fe,Al)4N (in the form of a \(\upgamma ^{\prime}\) -phase layer obtained by gas nitriding), TiAlN and CrAlSiN (in the form of vacuum ion-plasma coatings of micrometric thickness), and a carbon diamond-like coating (deposited in a vacuum using laser ablation technology). All coatings were applied to substrate samples made of 38CrMoAl steel – nitralloy, widely used in mechanical engineering for the production of tribocontact surfaces in friction units. The substrate material was specifically selected for further applied industrial use of the coatings based on the research results. The comparative analysis problem was solved using the desirability function construction technique proposed by E.S. Harrington. Desirability functions make it possible to reduce qualitative assessments of indicators to quantitative ones. Moreover, quantitative indicators can also be processed using the desirability function, which makes it possible to comprehensively characterize the object of study. In the conducted analysis, experimental values of the measured mechanical and tribological properties of the coatings were used as quantitative indicators. The results of the study revealed the advantages of nitride coatings in a set of indicators and allowed them to be ranked by wear resistance under sliding friction conditions.

摘要

The paper studies the possibility of solving a multicriteria problem of comparative wear resistance assessment of nitride coatings (Fe,Al)4N (in the form of a \(\upgamma ^{\prime}\) -phase layer obtained by gas nitriding), TiAlN and CrAlSiN (in the form of vacuum ion-plasma coatings of micrometric thickness), and a carbon diamond-like coating (deposited in a vacuum using laser ablation technology). All coatings were applied to substrate samples made of 38CrMoAl steel – nitralloy, widely used in mechanical engineering for the production of tribocontact surfaces in friction units. The substrate material was specifically selected for further applied industrial use of the coatings based on the research results. The comparative analysis problem was solved using the desirability function construction technique proposed by E.S. Harrington. Desirability functions make it possible to reduce qualitative assessments of indicators to quantitative ones. Moreover, quantitative indicators can also be processed using the desirability function, which makes it possible to comprehensively characterize the object of study. In the conducted analysis, experimental values of the measured mechanical and tribological properties of the coatings were used as quantitative indicators. The results of the study revealed the advantages of nitride coatings in a set of indicators and allowed them to be ranked by wear resistance under sliding friction conditions.
