The surface rust of carbon steel was cleaned by high-frequency and high-energy laser cleaning equipment with wavelength of 1064 nm.The effect of technological parameters on rust removal was studied during laser cleaning,and the element composition and relative content of rust surface,micro-region,line and point areas after laser cleaning were analyzed.The results show that the rust of the carbon steel surface can be completely cleaned by the pulsed laser under the optimized parameters.There is no oxygen element on rust surface,micro-region,line or point areas after laser cleaning,which indicates that there is no formation of iron oxide on the cleaned surface in the process of laser cleaning.
