Ni-金刚石复合镀层制备工艺及其性能研究
Preparation technology and properties of Ni-diamond composite coating
摘要
Abstract
In order to study the composite electrodeposition process of diamond consolidated abrasive grinding discs, the preparation technology and properties of Ni-diamond composite coating are studied in this paper.The influences of diamond concentration, current density, temperature and deposition time on the quality of composite coating are studied by scanning electron microscopy, microhardness tester and friction and wear tester.A series of preferred Ni-diamond composite electrodeposition process parameters are obtained: diamond concentration 40 g/L, current density 3 A/dm2, temperature 50 ℃, deposition time 90 min.The surface of Ni-diamond composite coating is flat, the diamond powder has a uniform deposition, and the wear resistance of the composite coating is obviously improved compared with the traditional nickel layer.关键词
