The formation mechanism of the amorphous Ni-Fe-P coating was studied by analysis of the forming thermodynamics, dynamics, and crystallography of the amorphous alloy. The results show that, in the initial stage of deposition a thin “crystal epitaxial growth ” layer first forms, and then transforms to amorphous gradually. The cross section in Ni-Fe-P coatings by electrolytic etching exhibits a banded structure of alternate dark and light bands. It is proposed that the banded structure is caused by a change in the P content with thickness, which is due to alternated depletion and enrichment of [OH] in the diffusion layer resulting from the generation and evolution of hydrogen gas. The amorphous Ni-Fe-P coating will be formed in proper composition, high nucleation rate and strongly hindered growth of the crystal nucleus. Amorphous Ni-Fe-P alloys form as islands, and grow up by layer.

研究了Fe-Ni-P合金镀层与45#钢、GCr15轴承钢、Q Sn6.5-0.4磷锡青铜、1Cr18Ni9Ti不锈钢、Cr镀层或Ni-P镀层分别组成摩擦副时在边界润滑下的摩擦磨损性能。结果表明：在给定的试验条件下, Fe-N i-P合金镀层与1Cr18Ni9Ti奥氏体不锈钢组成摩擦副对摩时容易产生粘着，磨损量和摩擦因数都比较高, 而且配副材料的抗擦伤临界载荷也很低；以Fe-Ni-P合金镀层分别与其它5种材料对摩时的耐磨性都相当好, 摩擦因数也都很低, 尤以Fe-Ni-P合金镀层/青铜的耐磨性能最好, 而GCr15轴承钢与Fe-Ni-P合金镀层组成摩擦副时的抗擦伤性能最佳, 然而45#钢与Fe-Ni-P合金镀层组成摩擦副对摩时的抗擦伤临界载荷却很低；在一般情况下, 用于与Fe-Ni-P 合金镀层配副材料的硬度愈低, 其在擦伤时对应的磨损体积损失的变化愈大。

以碳酸钙（CaCO3）晶须为填料，利用热压成型方法制备含0％-50％（质量分数）碳酸钙晶须增强聚醚醚酮（PEEK）复合材料，采用MM-200型摩擦磨损试验机研究碳酸钙晶须含量对复合材料与45#钢环配副的摩擦磨损性能的影响，利用扫描电子显微镜观察复合材料和钢环磨损表面形貌并分析其磨损机理。结果表明，碳酸钙晶须可以显著改善PEEK复合材料的减摩耐磨性能。随着CaCO3晶须含量增加，PEEK复合材料摩擦系数持续降低；磨损率随晶须含量增加呈先降后增趋势，并在晶须含量为15％时达最低值，相对纯PEEK降低86％,综合考虑，选择CaCO3晶须填充量为25％-30％时，复合材料具有最佳的摩擦磨损性价比.填充CaCO3晶须提高了复合材料承载能力，减少摩擦副表面粘着，阻止树脂的热塑性变形，提高复合材料的摩擦磨损性能.
