It was also found that the protecting effect of erodents on the coating surface does exist. The protecting effect will be more evident if using erosion efficiency of unit mass erodent of sand in the slurry to describe the erosivity of erodent. Besides a model is proposed to explain the protection process. The wear mechanism of the coating is the co-operation of ploughing, cracking and ablation.

对涂层的SEM分析可知，除冲蚀粒子在涂层表面的犁沟作用，冲蚀磨损的结果造成涂层的表面生成了系列针孔，其中的一部分为溶剂挥发所至，另外还存在由增强颗粒的剥落和裂纹的扩展造成的涂层剥落产生的孔洞，这将可能为水的吸收和扩散造成有利条件，使复合涂层亚表层产生内应力。

Two reasons can be explained the improvements of catalytic activities after the addition of Ce. One is the increase of the thermal stability of Ni-B and Ni-P nanoamorphous alloys, which retards the nanocrystalline Ni to aggregate during the exothermal reaction of benzene hydrogenation. The other is to make their grain sizes smaller, thus it increases the number of activity center in unit mass.

说明加入Ce提高催化活性的主要作用有两方面，一是提高Ni-B和Ni-P纳米非晶态合金的热稳定性，抑制催化苯加氢反应时大量放热促使纳米晶Ni的聚集长大；二是使生成的Ni-B和Ni-P纳米非晶态合金颗粒更为细小，从而增加单位质量样品的活性中心数量。
