运用化学镀方法,把空心微珠作为第二相加入化学镀镍和磷镀液中,制得以镍、磷和空心微珠为主的复合镀层.X射线分析显示,复合镀层经过热处理后由非晶态变成晶态.复合镀层经过热处理后显微硬度及摩擦学性能提高.复合镀层耐磨性比纯镍和磷镀层提高约30%,抗腐蚀性提高77%.运用SEM和XPS等对复合镀层性能和结构进行分析.

The fabrication and wear properties of electroless Ni-P/cenosphere composite coatings on steel are investigated.X-ray diffraction analyses show that Ni-P in the as-plated composite coatings is amorphous but changes to be crystalline after heat treatment.The microhardness of the composite coatings after heat treatment is significantly increased as compared with the as-plated coatings.Tribology test indicates that the composite coatings have good tribological performance.The wear-resistance of the composite coating is about 30% higher in volume than that of the pure Ni-P coating in dry condition.Anti-corrosion properties,measured by corrosion current,increase by 77% compared with the pure Ni-P coating.
