Tribological studies of thin diamond-like films synthesized using high-speed plasma jet

Abstract

In this paper, the tribological studies of diamond-like films under slip friction conditions are described. The films have been deposited from various materials (steel, aluminum, copper, and others). These films are deposited by the chemical vapor deposition method using a supersonic high-temperature plasma jet generated by a high-enthalpy plasmatron with a sectionalized interelectrode insert and a cold gas curtain for the walls of the discharge chamber. Tribological studies of the deposited films are performed using the friction simulator in the disc–ring system at rotational reverse motion. As a lubricant, 2% carboxymethylcellulose solution is used. Considerable differences in the tribological behavior depending on the substrate material, where the film has been deposited, are noted.
