Research of the structure and properties of nanostructured coatings based on chrome

Nanostructured chromium-based coatings have been researched. In some cases, it is expedient to use vacuum methods of deposition of chromium coatings by methods of thermal evaporation of pure chromium from tungsten coils or by ion-plasma (magnetron) sputtering method. Due to the low deposition temperature of coatings, there is a possibility of their formation on metallic and non-metallic materials. Based on the above, it is necessary to note the relevance of the study of the technology for the formation of chromium-based coatings by the ion-plasma method. To apply wear-resistant chromium coatings to samples made of R6M5 steel, the method of ion-plasma (magnetron) sputtering with a preliminary treatment of the surface with an ion source was used. The thickness, adhesive strength and corrosion resistance of chromium-based coatings were determined. Electron microscopy methods have been used to study the morphology of the surface and the size of nanoparticles in the structure of chrome coatings. It was revealed that depending on the modes of formation, the coating consists of nanoparticles with sizes from 15 nm to 230 nm.
