Based on the main working environment of polycrystalline silicon reduction furnace, the anti-corrosion test of 316L stainless steel,which is the main material,is carried out in this paper. Based on the pulse laser cleaning technology,the mechanism of improving the corrosion resistance of 316L stainless steel by different cleaning technologies was analyzed by comparing with various related detection technologies. The results show that the surface of 316L stainless steel after laser cleaning not only has higher cleanliness,but also its corrosion resistance has been improved. This study provides a reference for the surface cleaning of stainless steel in related fields.
