Abstract
Mechanisms of wear in galvanic AuNi and AuCo coatings have been studied using the methods of sclerometry and atomic force microscopy. It is demonstrated that the scratch test at a small load can be used for a comparative analysis of the resistance of metal coatings to abrasive wear. It is established that a developed surface relief related to the formation of grain agglomerates provides for a higher wear resistance of AuCo coatings as compared to that of smooth AuNi films, which is explained by dissipation of the elastic energy of the contact interaction of the sclerometric indenter with the sample surface.
