Effect of factors governing dry friction on structure formation for the tribological synthesis zone in composites based on copper

Features and peculiarities of structure formation for the friction zone in highly effective composite materials based on copper for prescribed experimental conditions (high contact loads and sliding rates, absence of a lubricant, operation in a high vacuum or in air) are considered. It is shown that reliable efficiency for a tribological system under friction conditions with action of high compressive forces and sliding rates is provided by material adaptation that is achieved via the tribological synthesis at the contact surfaces of a lubricating layer different in composition and structure from the original composite. __________ Translated from Poroshkovaya Metallurgiya, Nos. 3–4(448), pp. 14–21, March–April, 2006.
