Abstract：

On the surface of 304 stainless steel and 45 steel materials for common cold forging, wet sandblasting and dry sandblasting experiments were carried out respectively, and the influences of two sandblasting methods on the surface properties and states for common steel materials were measured and analyzed by the Mahr roughness meter and VHX-7000 ultra-high-precision microscope. Then, comparing with the dry sandblasting experiment and referring to the process with the polymer as cold forging lubricant, the influence mechanism of wet sandblasting was clarified by analyzing the similarities and differences of multiple roughness parameters. The results show that the roughness value of the material surface after wet sondblasting treatment is more stable than that of the dry sandblasting, its Rsk value is less than 0 and smaller than that of the dry sandblasting, Rku average value is closer to 3, and the blank surface after wet sandblasting treatment has relatively less sharp solitary peaks, which can form a stable and smooth concave-convex surface properties and states. On this basis, the indentation experiment shows that the bonding strength of the polymer coating layer by the wet sandblasting treatment is higher than that by the dry sandblasting treatment.
