- Based on evaluation method of corrosion damage, the processing surface corrosion resistance test has completed under different cutting parameters with the salt spray corrosion test machine. The corrosion damage of machined surface was detected by means of microcosmic-test. The effect of cutting parameters on corrosion resistance was analyzed during High-speed cutting process under simulated marine atmospheric environment. The experiment results show that the corrosion process of the processed surface is relatively slow at first. However the corrosion progress has accelerated tendency after 600 hours. The machined surface of cutting speed 4000m/min has satisfied corrosion resistance. The corrosion morphology of machined surface was obtained and analyzed. When the cutting speed exceeds a certain value 4000 m/min, the growth trend of micro cracks increase remarkably. The development and diffusion of corrosion pits is carried out along the direction of the tool marks, until the micro cracks appears in machined surface layer.
