Influences of Laser Treatment on Properties of Ni-P Layers Plated on Aluminum Substrates
-
摘要: 用Nd-YAG脉冲激光处理铝合金基体上化学镀的Ni-P合金镀层.与未处理的合金镀层相比,当激光能量密度为0.515 GW/m2时,Ni-P合金镀层的性能有明显提高,表面粗糙度降低而与基体的界面结合力增大,耐腐蚀性能也有显著的提高.

Abstract: A Nd-YAG pulsed laser was used to modify electroless plated Ni-P layers on aluminum substrates.The Ni-P layers were successfully modified with a laser power density of 0.515 GW/m2.The modified Ni-P layers exhibit smoother surface,better bonding strength with the substrate,and better corrosion resistance compared with untreated layers.-
