| 摘 要： | 本文通过比较化学镀Ｎｉ－Ｐ－Ｂ＿４Ｃ复合镀层、Ｎｉ－Ｐ－ＳｉＣ复合镀层、Ｎｉ－Ｐ合金层和电镀铬层的性能，发现Ｎｉ－Ｐ－Ｂ＿４Ｃ复合镀层是其中最理想的抗磨材料。试验证明：由于Ｂ＿４Ｃ微粒的硬度高于ＳｉＣ微粒，并且Ｂ＿４Ｃ本身又具有较高的抗显微切削能力，所以Ｎｉ－Ｐ－Ｂ＿４Ｃ复合镀层的耐磨性显著高于Ｎｉ－Ｐ－ＳｉＣ复合镀层和Ｎｉ－Ｐ合金层。由于电镀硬铬层的硬度随磨擦热的升高而迅速下降，所以其耐磨性远不及Ｎｉ－ＰＢ＿４Ｃ复合镀层。

| Abstract: | In this paper,the properties of electroless deposited Ni-P-B_4C coating,Ni-PSiC coating,Ni-P coating and electroplated chromium coating were compared. It was foundthat electroless deposited Ni-P-B_4C coating is the best wear resisting material. Since B_4Cparticles have higher hardness and anti-microcut capability,the wear resistance of Ni-P-B_4Ccoating is higher than that of NiP-P-SiC coating and of Ni-P coating. Because the coatinghardness will drop down rapidly with frictional heat rising, the wear resistance ofelectroplated chromium coating is worse in them. |
