【Abstract】 Chromizing Sbusequent solid solution nitriding multiple process of 304 austenitic steel has been studied.The microstructure and the phase structure of compound layer and the mechanical property was analyzed.The depth and case brittleness of compound layer and the distribution of the micro-hardness as well as chromium concentration were measured.The results show that a compound layer with good wear-resistance and corrosion resistance can be gained in 304 austenitic steel by chromizing sbusequent solid solution nitriding multiple process.更多还原
