摘要

The sliding layer (20) manufactured by magnetron-sputtering procedure, useful for tribological system from a piston and a cylinder in a combustion engine, comprises metal carbide particles deposited in a matrix from amorphous hydrogenous hard carbon. The metal carbide particles have a phase portion of 40-50 mol.% and a grain size of less than 2 nm. The sliding layer has a thickness of 1-50 mu m and a universal hardness of 7-15 GPa. Independent claims are included for: (1) sliding element with the sliding layer; and (2) procedure for manufacturing the sliding layer.
