Austenitic stainless steel, with its excellent corrosion resistance and good plasticity, is widely used in demanding industrial fields, such as chemical, food processing and Marine applications. However, when these materials need to operate in more demanding environments, such as high wear or pressure, additional enhancement of surface hardness and wear resistance is necessary. Electroplating hard chromium is an effective means to improve the surface properties of austenitic stainless steel, not only to improve the hardness, but also to maintain or improve the original corrosion resistance.
Electroplating hard chromium layer can significantly improve the surface hardness, improve wear and scratch resistance, thereby extending the service life of the substrate. The hard chrome layer also presents a low coefficient of friction, reducing heat and wear caused by friction during operation. Therefore, even if the austenitic stainless steel itself already has the basic corrosion resistance for industrial use, the electroplated hard chromium layer can further enhance its durability in harsher environments.
In order to ensure the good adhesion of the hard chromium layer, the austenitic stainless steel substrate usually needs to go through careful pretreatment steps, including mechanical grinding, cleaning and pickling, to clean the surface contaminants and oxides, and ensure a good bond between the coating and the substrate. Such pretreatment ensures the uniformity and adhesion of the coating, thus achieving an excellent blending effect between the coating and the substrate.
The electroplating process needs to be carried out in the electrolyte under the control of certain chemical composition and parameters. For austenitic stainless steel, appropriate temperature and current density are key to avoid unnecessary stress or deformation caused by electroplating. The thickness of the hard chromium layer after electroplating needs to be determined according to the application and performance requirements, and can be accurately controlled by electroplating time.
By using Bigely hard chromium plating process, the industrial application range of austenitic stainless steel has been significantly expanded to meet the diversified needs of modern industry for material properties. The perfect electroplating process not only ensures the wear resistance and corrosion resistance of the material, but also ensures the sustainability of industrial production and environmental sustainability.
