高硬度高耐磨Ni－P化学复合镀层

HIGH HARDNESS AND HIGH WEAR RESISTANCE Ni-P COMPOUND CHEMICAL DEPOSITION LAYER

用化学镀方法在铸铁表面沉积上一层复合镀层，并分别用ＨＸ－２００维氏显微硬度计、Ｍ－２００型磨损试验机及自制的划痕试验机测定了复合镀层的硬度、耐磨性以及结合力。结果表明：Ｎｉ－Ｐ－Ｂ＿４Ｃ、Ｎｉ－Ｐ－金刚石粉复合镀层具有较高的硬度、高耐磨，但结合力数值较低。

The hardness, the wear resistance and the adhesive force of the Ni-P compound chemical deposition layer were measured,The results indicated that the Ni-P-B_4C,the Ni-P diamond partical compound layer have high hardness and high wear redistance,but the adhesive force is poor.
