A review of studies in the field of production of coatings on metals by means of mechanical alloying

The mechanical alloying method is widely used for production of powdered alloys. However, focused studies have shown that this method may also be used for deposition of coatings. Therefore, there is a need to summarize the results obtained and assess opportunities for creation of coatings by the mechanical alloying method in order to improve performance characteristics of different metal materials. This review presents the results of the reported works concerning the structure and properties of coatings deposited by means of mechanical alloying onto titanium and titanium-based alloys, carbon and alloyed steels, aluminum and aluminum-based alloys, copper, and nickel substrates. The composition, hardness, and thickness of the coatings are discussed, as well as defining features of their structure and their influence on the operating properties of materials. The impact of the main parameters of the mechanical alloying process on the coating characteristics and specific features of the mechanism of mechanical intermixing during mechanical alloying are analyzed.
