碳钢表面进行化学镀处理,对提高碳钢的耐磨性能有重要作用。在Q235钢表面制备Ni-P镀层及不同纳米Al2 O3颗粒含量的Ni-P-Al2 O3镀层。通过扫描电子显微镜、X射线衍射仪和摩擦磨损实验机对镀层的表面形貌、相组成及摩擦磨损性能进行研究。结果表明：Ni-P-Al2 O3镀层的磨损量、摩擦系数均小于Ni-P镀层,分别为2．6 mg和0．5；Ni-P-Al2 O3镀层的磨损以犁沟磨损为主,磨粒磨损和黏着磨损为辅,Ni-P镀层的磨损为犁沟磨损。该研究可以为Ni-P-Al2 O3镀层的实际应用提供理论支持。

This paper is concerned with a research motivated by the realization that the electroless plating on carbon steels plays an important role in improving their wear resistance. The study involves fabricating the Ni-P electroless coating and electroless Ni-P-Al2 O3 composite coatings with different con-tent of nano-Al2 O3 particles on Q235 steel and characterizing the surface morphology, chemical composi-tion and wear properties using scanning electron microscopy, X-ray diffraction and friction and wear tes-ting machine. The study shows that the Ni-P-Al2 O3 composite coatings have abrasion loss and the frication coefficient, both of which are lower than those of Ni-P electroless coating, and are 2. 6 mg and 0. 5, re-spectively;Ni-P-Al2 O3 composite coatings are governed by the wear mechanism dominated furrow and complemented by abrasive and adhesive wear. The Ni-P electroless coating ischaracterized by furrow wear. The research may provide the theoretical support for the practical application of electroless Ni-P-Al2 O3 composite coatings.
