1, impumuzo yengcindezi ngaphambi kokucwenga lapho amandla amakhulu okuqineka okukhulu kunokhiye ongu-1034Mpa kanye nezingxenye ezibalulekile ngaphambi kokucwecwa kufanele kube ku-200±10℃ ukukhululeka kwengcindezi isikhathi esingaphezu kwehora elingu-1, izingxenye ze-carburizing noma zokucisha indawo kufanele zibe ku-140±10℃ amahora angaphezu kwama-5.
2. I-ejenti yokuhlanza esetshenziselwa ukuhlanza akufanele ibe nomthelela emandleni okubopha we-coating futhi kungabikho ukugqwala ku-matrix.
3. Isixazululo sokwenza kusebenze i-asidi kufanele sikwazi ukususa imikhiqizo yokugqwala nefilimu ye-oxide (isikhumba) ebusweni bezingxenye, ngaphandle kokugqwala ngokweqile ku-matrix.
4,othayelaingasetshenziswa zincate lashukumisa noma inqubo chloride lashukumisa, kufanele asebenzise izithasiselo ezifanele ukuhlangabezana nezidingo zalesi enamathela standard.
5, emva Plating ukukhanya kufanele kwenziwe ukwelashwa ukukhanya.
6, passivation ukususa hydrogen izingxenye kufanele passivation ngemva ukususwa hydrogen, passivation ngaphambi isicelo 1% H2SO4 noma 1% hydrochloric acid kusebenze 5 ~ 15s.I-passivation izophathwa nge-chromate enemibala ngaphandle uma kucaciswe ngenye indlela emidwebeni yokuklama.
