The laser ablation and chemical etching composite processing method for the sample processing experiments to study the laser pulse energy, pulse width, repetition frequency and laser beam scanning speed and other parameters on the surface morphology of the metal sample processing rules and mechanisms The influence of the kind and concentration of corrosive medium on the quality of the machined surface was studied. The results show that chemical etching can greatly reduce the surface of the sample processing slag, to reduce the surface roughness plays a good role; laser energy density, pulse width, repetition frequency and laser beam scanning speed and other parameters of the metal surface quality of the sample Have a significant impact.
