Compound layer of iron nitride can be considered as a ceramic layer. It is very wear resistant.(HRC > 62~72, depending on alloying elements included.) This layer prevents metal-to-metal contact and therefore prevents adhesive wear from happening. This white compound layer is also very corrosion resistant, esp. a post-nitriding oxidation is added that turns the color of workpiece into shining black. VW is using nitrocarburizing process on their ball studs, you guys can also give it a try to replace the EVERLUBE coating.

雪鉄龍 C3 水箱風扇 貴死人!
台中COSCO 附近這家, 上次(1年半前) XX離合器片破裂, 雜音頗大, 給師傅檢查, 先換惰輪與皮帶後, 雜音還在 最後才判定是 離合器片破裂 換零件要價1.3萬, 且車子要 留兩天. 我說改天再來, 先把沒壞的惰輪與皮帶換回去, 還不肯, 說換上就不退了, 真是氣死我了. 折騰半天,最後是: 裝新的上去工資600, 換回我原來零件工資600, 付了1200 才脫身. 之後, 就一路殺到洲際棒球場旁這家(4:30 p.m.到), 詢價, 林老板開價11000. 第二天中午前交車. 就給他做了.
