自从Willian Blum将金相方法运用于镀层结构的研究以来,许多分析工作(主要是透射电镜和X射线分析)都表明槽镀镀层的主要强化机制是细晶粒。此外,镀层中还存在着相当数量的位错和微孪晶。刷镀镀层与槽镀镀层相比。刷镀镀层具有更高的硬度和耐磨性,这也是许多单位得 Since Willian Blum applied the metallographic approach to the study of coating structures, much of the analytical work (mainly by transmission electron microscopy and X-ray analysis) has shown that the major strengthening mechanism for trench plating is fine grained. In addition, there is a considerable amount of dislocations and micro-twists in the coating. Brush plating compared with the groove plating. Brush plating with higher hardness and wear resistance, which is also many units too
