Ngemva kweishidi lensimbi engagqwaliidwetshwa ngocingo, isalokhu igcina ukumelana nokugqwala kanye nemiphumela yokuvimbela ukugqwala.Nokho, uma kuqhathaniswa namashidi ensimbi engagqwali angazange adwebe ngocingo, ukusebenza kungase kwehle kancane.
Njengamanje, izindlela zokwelapha ezivame kakhulu ezingaphezulu kwamashidi ensimbi engagqwali indawo ekhanyayo ne-matte surface.Amashidi ensimbi engagqwali e-matte, ngemva kokwelashwa kokudweba ngocingo, amelana kakhulu nokugqokwa kunamashidi ensimbi engenasici akhanyayo.Nokho, ukumelana nokugqwala nokusebenza kokuvimbela ukugqwala kwamashidi ensimbi engagqwali ngemva kokwelashwa kokudweba ngocingo kungase kwehle.Ukunakekela okungalungile ngokuhamba kwesikhathi kungase kuholele ekugqwaleni kwangaphambili uma kuqhathaniswa nendawo ekhanyayoamashidi ensimbi engagqwali.
Insimbi engagqwaliingenye yezinsimbi ezingenasici ze-austenitic, ikakhulukazi ezakhiwe ngezinto ezifana nekhabhoni, i-nickel, ne-chromium.I-Chromium ingenza ifilimu yokuvikela enothe nge-chromium ebusweni bamashidi ensimbi engagqwali, ivimbele ukugqwala nokugqwala okuqhubekayo.Ukwelashwa kokudweba ngocingo kungalimaza ifilimu yokuvikela enothe nge-chromium ngaphezulu, okuholela ekwehleni kokumelana nokugqwala kanye nokusebenza kokuvimbela ukugqwala kwamashidi ensimbi engagqwali.Ezindaweni ezinokhahlo lapho kutholakala umoya, ilanga nemvula, ukugqwala nokugqwala kungenzeka kalula.
Ngaphambi kokwenza ukwelashwa kokudweba ngocingo emashidini ensimbi engagqwali, kubalulekile ukusebenzisa ukwelashwa kokuvimbela ukugqwala kwe-passivation.Ukwelashwa kwe-passivation kusekelwe embonweni wefilimu emincane, okuphakamisa ukuthi ukudlula kwenzeka lapho insimbi ixhumana nendawo, okuholela ekwakhekeni kwefilimu encane kakhulu, eminyene, emboze kahle endaweni yensimbi.Le filimu isebenza njengesithiyo, ivimbele ukuthintana okuqondile phakathi kwensimbi nokugqwala futhi ivikele insimbi ekugqwaleni.
