摘要
采用化学复合镀技术,在铜箔基体上沉积硼酸铝晶须增强镍磷基复合镀层,并研究了该复合镀层的组织和力学性能.结果表明:随着镀液中硼酸铝晶须含量的增加,复合镀层表面的颗粒粒度变小;复合镀层的最大延伸率、断面收缩率和拉伸断口侧面裂纹的密度增加,但抗拉强度和弹性模量降低.
The Ni-P-aluminum borate whisker （Ni-P-AIBOw） composite electroless coating was deposited on the surface of copper foil using composite electroless plating technology, and microstructure and mechanical properties of the composite coatings were investigated. The results indicate that the grain size on the sample surface decreases with increasing in A1BOw content. Meanwhile, the maximum extensibility, the reduction of area and the crack density of the fracture side of Ni-P-AlBOw, composite electroless coatings increase with the increase of AlBOw content, while the tensile strength, the fracture strength and elastic modulus decrease.
