本文叙述了用纯氮气作为炉内气氛可以防止被处理工件脱碳、增碳和氧化等缺陷,并能用于作高速钢,工具钢等高合金钢的淬火介质。叙述了以纯氮为炉内气氛能防止脱碳、氧化的机理及高合金试样在此炉内气氛中试验的 This paper describes the use of pure nitrogen as the furnace atmosphere can be processed to prevent decarburization, carbon and oxidation defects, and can be used for high-speed steel, tool steel and other high-alloy steel quenching medium. The mechanism of preventing decarburization and oxidation by using pure nitrogen as the atmosphere in the furnace and the test of the high alloyed specimen in the atmosphere of the furnace are described
