Problems solved by technology

The present invention realizes that less silver is used to endow 304 stainless steel with better antibacterial effect, and the antibacterial rate can reach more than 95%, while improving the corrosion resistance of stainless steel, and the thickness of the surface modification layer can reach 520um, although this method reduces The thickness of the surface modification layer is increased, but it only improves the antibacterial property of stainless steel by laser cladding silver layer, which has little effect on the improvement of its overall performance, and its durability of stainless steel is poor

Description

technical field [0001] The invention belongs to the field of surface modification of stainless steel, and in particular relates to a surface treatment method for strengthening the antibacterial durability of stainless steel sanitary ware. Background technique [0002] Stainless steel has good corrosion resistance, heat resistance, excellent mechanical strength and ductility, and has a bright surface. It has been widely used in construction materials, sanitary ware, kitchen supplies, household appliances, and medical equipment. In the outdoor use environment, the surface of stainless steel products is easily contaminated by dust and oil; in indoor and other environments, water stains often adhere to it, thereby breeding bacteria, threatening people's health, and causing cross-infection in public places . Stainless steel products need to be cleaned regularly during use, especially for stainless steel products used in curtain walls, roofs and outdoors. Cleaning is difficult an...
