Study on Optimization of Laser Cleaning Process for TC4 Titanium Alloy Surface Absorbing Coating
The NDW-63 absorbing coating on TC4 titanium alloy was cleaned by nanosecond pulse laser.The effects of laser power and scanning speed on the surface morphology,roughness,composition,physical phase and microhardness of the cleaned sample were studied.The research results show that the reasonable optimization of the process parameters can remove the absorbing coating on the surface of titanium alloy and obtain a better surface morphology.It can also improve the surface hardness of the substrate.
