Tribological Characteristics of Metal-Oxide and Hybrid Composite Coatings

Resumo

It is shown that the tribological characteristics of structural steels under different conditions of rubbing can be significantly increased by depositing a layer of composite chemical coatings with nickel-phosphorus alloy with inclusions of disperse particles of the chromium, aluminum, titanium, and zirconium oxides as well as boron carbide, titanium nitride, diamond, and copper phthalocyanine. The influence of the nature, size, and content of disperse particles in composite coatings on the wear resistance of the tribo-contact was studied. The optimal conditions for depositing composite coatings with heightened wear resistance were determined.
