摘　　要：通过对ABS基树脂化学镀镍-磷层的腐蚀黑化,得到反射率在0.5%以下的超黑表面。以不同磷的质量分数的镀层为研究对象,研究了腐蚀时间、镀层中磷的质量分数对镀层表面构造一种多孔结构的形貌特征的影响。通过对ABS树脂化学镀镍-磷层硝酸溶液腐蚀黑化前后电镜图,以及腐蚀镀层之间反射率的比较,得出磷的质量分数为5.2%～7.1%的镀层,在40℃硝酸溶液(1∶1)中腐蚀20～50s,镀层表面可以得到超黑的效果。An ultra-black surface with a reflectivity less than 0.5% was obtained by blackening the electroless Ni P coating on ABS resin. The effects of blackening time and the mass fraction of phosphorus of thc coating on the morphology of a porous coating was investigated. Coating morphologies before and after blackening were taken by SEM photos, and reflectivity by Datacolor. The comparisons show that an ultra black coating surface can be obtained by dipping the ABS resin with electroless Ni P coating of mass fraction of 5.2%-7. 1%, phosphorus in nitric acid（1 ： 1） at 40 ℃ for 20-50s.
