| Ukutyunjwa | Uphawu | Inkcazo |
| Kubanda kugqityiwe (kunzima) | BK(+C) | Iityhubhu azifumani nyango lobushushu emva kokumila kwengqele yokugqibela kwaye, ngenxa yoko, zinokuchasana nokonakala |
| Kubanda kugqityiwe (Kuthambile) | BKW | Unyango lokugqibela lobushushu lulandelwa ngumzobo obandayo obandakanya ukuguqulwa okulinganiselweyo.Ukuqhubela phambili okufanelekileyo kuvumela iqondo elithile lokubumba okubandayo (umzekelo. ukugoba, ukwandisa) |

Ukuvelisa Inkqubo kunye neenzuzo
Izinto zensimbi zebillet, emva komzobo ochanekileyo, i-oxidation yasimahla kunye nonyango lobushushu obuqaqambileyo (i-NBK state), uvavanyo olungonakalisi, ukugungxulwa koxinzelelo oluphezulu kunye ne-acid pickling yomngxuma ongaphakathi wombhobho wentsimbi, unyango lwe-oyile ye-anti-rust kwiindonga zangaphakathi nangaphandle. wombhobho wentsimbi, kunye nonyango lokuthintela uthuli kuzo zombini iziphelo zesigqubuthelo.
1. I-Th yangaphakathi kunye neendonga zangaphandle zombhobho wensimbi azinayo i-oxide layer;
2.Ukumelana noxinzelelo oluphezulu, akukho kuvuza, ukuchaneka okuphezulu, ukuguda okuphezulu;
3. Ukugoba okubandayo ngaphandle kokuguqulwa, ukwandiswa, ukubethelwa ngaphandle kokuqhekeka;
4. Unyango lothintelo lomhlwa ngaphezulu.
