This paper investigates the depletion of a thin lubricant film subjected to laser heating in an inert gas environment, and we experimentally elucidate the fundamental characteristics and mechanisms related to lubricant depletion in air and inert gas environments. In addition, fundamental experimental studies are conducted to understand the structural stability or degradation, such as through oxidation and graphitization of diamond-like carbon (DLC) thin films subjected to laser heating, in an… CONTINUE READING
