本文对有小孔和窄沟槽的零件进行了可控气体渗氮的试验研究，并与传统气体渗氮法进行了比较。试验结果表明：可控气体渗氮工艺对具有通孔，盲孔或窄沟槽的零件均可得到均匀连续的化合物层。这对工业生产很有实用价值 In this paper, experiments on controlled gas nitriding of parts with small holes and narrow grooves were carried out and compared with the traditional gas nitriding method. The experimental results show that the controlled gas nitriding process can obtain uniform and continuous compound layer for the parts with through-hole, blind hole or narrow groove. This is very useful for industrial production
