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.

通过热喷涂的方法制备了添加稀土组分和适量铜组元的RE-Fe基合涂层，采用液态浸法、电化学测试、盐雾实验以及涂层表面腐蚀形貌SEM观察等方法对不同成分、不同喷后处理工艺的RE-Fe基合金涂层的耐腐蚀性能进行研究。结果表明：添加适量的稀土组分和铜组元，使Fe基合金涂层的自腐蚀电位正移，维钝电流密度和致钝电流密度下降，明显地提高了Fe基合金（Fe-Cr-Ni-B-Si）涂层在酸类腐蚀介质中的耐腐蚀性能；同时也有效地提高了涂层搞盐雾气氛腐蚀的能力；其中以添加2%RE氧化物（质量分数）涂层（封孔后）的综合效果最佳。

用MM200磨损试验机和45钢环配副，研究不同含量碳酸钙（CaCO3）晶须和10%的聚四氟乙烯（PTFE）共同填充聚醚醚酮（PEEK）复合材料的摩擦磨损性能，用扫描电镜观察磨损表面形貌并分析磨损机理。结果表明，随着复合材料中晶须含量增加，摩擦系数持续降低，最低可隆到纯PEEK的1/2；复合材料的磨损率随晶须含量的增加先大幅度减小后又缓慢回升，当晶须含量为15%-20%时，磨损率隆至3.3×10-7mm3/Nm，仅为纯PEEK的3.6%,20%CaCO3/10%PTFE/PEEK 综合摩擦学性价比较好。CaCO3晶须PEEK减少了复合材料在摩擦过程中摩擦副表面粘着和剥层，阻止基体树脂的热塑性变形，同时PTFE的俦粘着转移使得复合材料在对偶件表面形成连续、均匀的转移膜，两者协同有效降低摩擦系数和磨损率，提高材料的摩擦学性能。

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.

The wear mechanism of amorphous Ni-Fe-P coating was discussed. The wear resistance of the amorphous Ni-Fe-P coatings was tested on a Timken wear apparatus, and the wear track of the amorphous Ni-Fe-P coatings as-deposited and heated at various temperatures was observed by SEM. The results show that the wear resistance reaches a maximum value at NaHPO2·H2O concentration of 5g/L, and heating at 400 ℃. The wear mode of the coating will change with the heating temperature increasing from pitting + plowing at 200 ℃to pitting at 400 ℃, and to plowing at 600 ℃. The pits on the worn surface of the amorphous Ni-Fe-P coating result from the tribo-fatigue fracture. The cracks of spalling initiate at pits and propagate at certain angle with the sliding direction on surface, and then extend into sub-surface along the poor Players or the interface between layers. Finally under repeated action of the stress in the rubbing process the cracks meet and the debris forms. The generation of the pits and spalling is related with the internal stress, brittleness and layer structure of the amorphous Ni-Fe-P coating.

测定了电沉积Fe-Ni-P非晶合金镀层在不同温度下热处理后的硬度, 在环-块磨损试验机上对镀层的耐磨性进行了研究, 对镀层的显微组织和磨损表面作了观察与分析, 就其强化机理和磨损机理作了分析与探讨. 镀层的硬度和耐磨性均随热处理温度上升而提高, 400 ℃时都达到极大值, 最高硬度为HV11.2GPa；在400 ℃以上, 镀层的硬度和耐磨性均随温度升高而降低, 此时镀层的含磷量越多, 硬度越高, 耐磨性越好；在500 ℃以下热处理后镀层的磨损机理主要为点蚀和剥落, 剥落坑随着温度的升高而减少；600 ℃以上热处理镀层发生的是磨粒磨损。
