The paper examines the ability to control a number of tribological and mechanical characteristics of coatings that provide optimal ratios of hardness to effective modulus of elasticity based on the principle of multi-element. The indicated values of ratio provide a high value of hardness and low values of the coefficient of friction and wear. In addition, reduction in the difference of the elastic modulus of the substrate and the coating allows to increase the adhesive properties. Criteria for transient contact conditions are given, as well as the values of the ratio of hardness to elastic modulus, which characterize the resistance of the coating to plastic deformation. The results of the study can be used in friction units, especially in aerospace machines, mechanisms and instruments.
Keywords: tribology, nanostructured coating, friction coefficient, wear coefficient, criterion of transition of the contact mode, hardness, effective modulus of elasticity.
