长效自润滑耐磨耐蚀复合镀层制备工艺及性能研究
Preparation Process and Properties of Long Term Effect Self-lubrication Composite Coating with Wear Resistance and Anti-corrosion Propeties
摘 要
以长效自润滑耐磨、耐蚀复合镀层制备技术,采用45#钢为基体材料、Ni-B为基底合金、Ni-W-P为基质合金、添加耐磨人造金刚石微粒和固体润滑剂(CF)n微粒,镀制Ni-B和Ni-W-P/金刚石-(CF)n双层复合镀层.试验结果表明:该工艺得到的Ni-B和Ni-W-P/金刚石-(CF)n双层复合镀层表面光亮,质感均匀,粗糙度为Ra0.2；镀层结合力良好；耐蚀性优良；经过相同次数磨损试验,磨损量仅为未镀试件的21.2%.

Abstract
A long term effect self-lubrication composite coating with wear resistance and anti-corrosion properties was obtained by electroless composite plating.Adding diamond and (CF)n particle in the Ni-W-P composite coating,a two-layer composite coating of Ni-B and Ni-W-P/Diamond-(CF)n was gained.The surface of the two-layer composite coating was bright,homogeneous,and its harshness was Ra 0.2.The bond strength and corrosion-resistance of the coating were good.The wearing amount of the specimen with coating was only 21.2% of that without coating.
