利用化学镀或电镀方法在镀液中加入纳米粒子(金刚石、碳化硅、氮化硅等 ) ,制备成提高耐磨性的复合镀层 ,很多年来都有人在研究 ,但受材料的限制 ,以前用微米级材料复合镀层耐磨性提高 ,工艺实现难度大 ,主要有 :1)剥落问题 ;2 )下沉问题。随着纳米材料的开发 ,人们可获得粒度 The use of electroless plating or electroplating methods in the plating solution by adding nanoparticles (diamond, silicon carbide, silicon nitride, etc.), prepared to improve the wear resistance of composite coatings, people have been studying for many years, but subject to material restrictions, previously used The wear resistance of micron-sized composite coatings is increased, the process is difficult to achieve, mainly: 1) spalling problem; 2) sinking problem. With the development of nanomaterials, one obtains particle size
