硼含量对化学镀镍硼合金层组织和性能的影响

Effect of Boron Content on Structure and Properties of Electroless Deposited Nickel—Boron Alloy Coating

本文研究了硼含量与化学镀镍硼合金层组织和性能的关系。结果表明,硼含量对镍硼合金层的表面形貌影响不大。硼含量低的合金层为晶态;随硼含量的增加,其结构逐渐转变为非晶态。晶态镍硼镀层的显微硬度比非晶态镀层的高,其耐磨性也优于非晶态镀层。

This paper deals with the relation between born content and the structure, propariea of electroless Ni—B coatings. The result shcws that botcn content has a little effect on the surfaee morphology of elestrolcss Ni—B alloy coating The strocture of the coating containing lower boron is crystalline; Its structure is converted gradully into noncrystal with increasing boron,The hardness and wear resistance of crystalline coating is higher than those of noncrystlline coating
