The results show that the carburized case uniformity can be ensured through sand blasting or phosphating before carburizing, and NH3 is filled during carburizing.
结果表明：零件渗碳前经吹砂或磷化，渗碳时通入NH3，能够保证渗碳层均匀。
The technical promotion of used equipment is realized through microcomputer controlling for carburizing and carbonitriding with less energy consumption;
②渗碳、碳氮共渗、表面热处理实现微机控制，老设备换新貌，节能降耗效果好，显著提高热处理工艺技术水平；
