农业技术的发展提出有必要创造制造零件的新工艺方法,以保证零件具有高的耐磨性和疲劳强度等。经过低温碳氮共渗(又称短时氮化)的钢和铁,在很大程度上很满足上述要求。低温碳氮共渗后结构钢零件的表面通常
The development of agricultural technology proposed the need to create new manufacturing methods of parts, to ensure that parts with high wear resistance and fatigue strength. After low temperature carbonitriding (also known as short-term nitriding) of steel and iron to a large extent to meet the above requirements. The surface of structural steel parts after low temperature carbonitriding is usually
