介绍了纳米复合镀层制备技术存在的问题,综述了纳米复合镀层强化技术的现状,重点分析了液相等离子体强化技术的原理和分类。利用高能量密度的液相等离子体将镀件与基体加热到熔凝状态,使得镀层材料与基体材料相互渗透,形成再结晶组织,实现了两者的冶金结合,提高了镀层与基体的结合强度。
The problems existing in preparation technology of nanocomposite coatings were introduced. The current status of nanocomposite coatings strengthening technology was reviewed. The principle and classification of liquid phase plasma enhanced technologies were analyzed emphatically. The liquid phase plasma with high energy density heats the plating and the substrate to the fused state, so that the plating material and the matrix material penetrate each other to form a recrystallized structure, thereby achieving metallurgical bonding between the two and increasing the bonding strength between the plated layer and the substrate .
