采用维氏压痕法研究了非晶态Ni-P合金镀层在压痕作用下的塑性变形，并研究了氢对镀层塑性变形的影响。结果表明，在压痕作用下压痕周围和底部出现环行的剪切带，压痕塑性区尺寸与压痕载荷的平方根成正比，氢可以促进局部塑性变形，降低镀层的屈服强度。
The plastic deformation and effect of hydrogrn on deformation of electroless Ni-P amorphous coatings were studied through indentation test. The results showed that circular shear bands formed around the indent and the plastic zone size increased linearly with the square root of the applied load, hydrogen could enhance localized plastic deformation, deduced the yield strength.
