Self-lubricating glass composite nanocoatings

The friction and wear characteristics of the developed nanostruc­tured glass-composite self-lubricating coatings, the structural components of which have a qualitative effect on the graphitization process and ensure the production of an a-graphite surface layer that minimizes contact parameters, are investigated. The positive role of the glass phase in the form of aluminoborosilicate, which affects the tribological properties of coatings, has been established. It is established that an increase in adhesive strength is achieved due to the forma­tion of a surface layer of glassy sodium silicate during spraying. It is stated that the intercala­tion of the graphite layer by the particles of the subsurface zone does not affect the tribo­technical characteristics of the coatings. The developed nanostruc­tured glass-com­posite coatings demonstrate high anti-friction characteristics throughout the entire load-speed range of tests.
