Detected by EDXA,SEM,AES,IFR,they show that the obtained sample coating is homogeneous,the thickness of the coating is over 100nm,and the emissivity of the carbonyl iron is decreased obviously from 0.89 to 0.70.

• 通过扫描电镜、光电子能谱分析、俄歇能谱、红外发射率等性能测试 ；结果表明 :所制备的样品镀层均匀 ；镀层的成分为镍磷合金 ；镀层厚度超过 10 0nm ；红外发射率显著降低 ；羰基铁粉体红外发射率由 0 .；89降低为 0
