| 摘 要： | 采用 Akashi 显微硬度算和 Taber 耐磨损试验机,测量无电解复合镀层 Ni-P-Al_2O_3,Ni-P-SiC 的硬度和耐磨性能,发现复合镀层有很高硬度和耐磨性。经适当的热处理后,镀层硬度提高了四倍。差热分析和 X-射线衍射分析结果表明,镀层性能的改善是由于新相 Ni_2P 析出所致。

| Abstract: | The hardness and wear resistance performace of Ni-P-Al_2O_3 and Ni-P- SiC composite coatings heat treated at different temperature are measured by Akashi micronardness detector and Taber wear tester. It is found that the Ni-P-SiC coating has the nighest hardness and the best wear resistant per- formance.After adequate heat treatment,the hardness of Ni-P-SiC coating increases four times. The results of differential thermal analysis and X- Ray diffraction show that it is due to the formation of Ni_3P hardening phase. |
