摘要： The invention relates to a piston ring for internal combustion engines, the piston ring comprises a steel or cast iron base material with a coating of chromium nitride deposited by a physical vapor deposition process on a sliding surface of the piston ring, wherein the coating is composed of a columnar crystal structure of CrN with the following features: (a) an oxygen content in solid solution of 0.5 to 2.5 wt %; (b) a content of uniformly dispersed micro-pores of less than 10 % in volume of the coating; and (c) an X-ray diffraction intensity ratio of (111) planes to (200) planes parallel to the surface in the range of 0.80 to 1.20.

摘要： A bearing lining has a bearing backing layer provided with a coating comprising a first overlay layer and a second overlay layer, the first overlay layer being provided between the bearing backing layer and the second overlay layer. The first and second overlay layers each comprise a matrix material and a soft-phase material that is substantially insoluble in the matrix and dispersed within the matrix as soft-phase particles. The first overlay layer comprises a higher proportion by weight of a grain size reduction additive than the second overlay layer.
