摘要：

The composition of electrolytes for the formation of wear-resistant oxide layers on the silicon aluminum alloy by the method of high-voltage electrochemical oxidation is developed. Obtained anodic oxide films possess a thickness of up to 100 mu m and a hardness of up to 5.5 GPa. The frictional behavior of oxide films in different counter-body-substrate friction pairs under conditions of dry friction was investigated. It was established that the use of the "oxide coating-oxide coating" pair in the dry friction regime shows the highest wear resistance in comparison with friction pairs of bare alloys.
