1. I-Chrome plating phezulu ukuze kuthuthukiswe ukumelana nokugqokwa;
2. Izimbobo ezixegayo zifakwe i-chromium ukuze kuthuthukiswe ukugcinwa kwamafutha angaphezulu futhi kusheshiswe ukungena;
3. Kuqoshwe endaweni engaphakathi ukuze kuthuthukiswe ukunwebeka;
4. I-groove yokugcina uwoyela ihlinzekwa endaweni engaphandle yendandatho ukuze kube lula ukugcoba;
5. Ingaphandle lendandatho limbozwe ngethusi ukuze kube lula ukungena;
6. I-molybdenum ifafazwa ngaphandle kwendandatho ukunciphisa ukunamathela nokuguga.

Kufinyezwe kanje:
Thuthukisa ukumelana nokugqokwa: i-chrome plating, i-nitriding
Thuthukisa ukusebenza kokuqala kokugijima: i-copper plating, i-phosphating, i-sulphurizing
Ukuvimbela ukunamathela kokunamathela: fafaza i-molybdenum
