摘　　要：利用宏观分析、显微检验、硬度测试和装车试验等手段，对引进奥地利重型汽车内齿圈按照新的气体氮碳共渗工艺处理后的质量进行了研究。结果表明，新工艺不仅能达到国外设计指标，还比Tenifer工艺具有更高的抗磨损能力与更低的成本。The quality analysis for gas nitrocarburized inner gear ring of heavy truck imported from Austria was taken by means of macro/micro-examination, hardness measuring and running test. The results showed that the gas nitrocarburized inner gear ring can meet the origin design demands and the wear resistance is better than that of Tenifer process treated(salt bath nitrocarburizing),the technology cost is also lower.
