非晶态镍磷合金的组织结构与性能

研究了化学沉积非晶态镍磷合金的组织结构与性能。结果表明，随着沉积层中磷含量的增加，合金的非晶化趋势提高，非晶态镍磷合金层的硬度和耐磨性能下降，且明显低于晶态镍磷合金；经过大于６１３Ｋ的时效处理，非晶态镍磷合金晶化且有Ｎｉ３Ｐ生成，沉积层的硬度和耐磨性得以提高并超过晶态合金；非晶态镍磷合金经过时效处理晶化后且组织结构发生变化，耐腐蚀性能下降，硬化性能则提高。

MICROSTRUCTURE AND PROPERTIES OF AMORPHOUS Ni P ALLOYS

The microstructure and properties of amorphous nickel phosphorus alloys processed by electroless deposite have been studied. The results show that the amorphous tendency of the alloys rises with phosphorus content, and the hardness and wear resistance decrease, which are obviously lower than that of crystal Ni P alloy. While the amorphous Ni P alloys is aged at higher temperature than 613 K, they crystallize to precipitate Ni 3P, so that the hardness and wear resistance of the coatings incerase and are superior to the crystal alloy; after aging treatment to crystallize , amorphous Ni P alloys possess lower corrosion resistance and greater hardening properties.
