奥氏体不锈钢活性屏低温离子渗碳工艺研究

he use of Active Screen Plasma heat treatment technology for low-temperature plasma carburized austenitic stainless steel (ASPC) processing, can be formed on the surface layer of stainless steel without chromium carbide precipitation of the supersaturated solid solution of carbon (Sc-phase). Treated austenitic stainless steel without compromising corrosion resistance can be based on the substantial increase in the hardness of stainless steel surface and address of the stainless steel DC-ion carburizing temperature uniformity is poor, there is the workpiece edge effects and other issues, ASPC carburized surface of the sample basic color of stainless steel can be maintained. Through the active on-screen activity of nano-particles sputtered down the microscopic analysis showed that these particles are Fe3C, Fe2C5 neutral particles, in the ASPC to play the role of carburizing carrier, so the process of carburization ASPC should also be a sputtering - adsorption - desorption process.
