Nekuenderera mberi kwekusimudzira kweindasitiri yekugadzira simbi, simbi isina tsvina yakawana kushandiswa kwakawanda muhupenyu hwezuva nezuva, kugadzira maindasitiri, uye minda yemauto.Munguva yekugadzira, kugadzira, uye kushandiswa kwesimbi isina tsvina, nzvimbo yayo inogona kuratidza mavara asina kuenzana emavara kana corrosion traces nekuda kwekukwira-tembiricha oxidation, yepakati corrosion, etc. Nezvikonzero zvekunaka kana kugadzirisa nyaya idzi,simbi isina tsvina picklinguyepassivation mhinduroanowanzo shandiswa kuchenesa makemikari uye passivation kurapwa.Iyi nzira inoumba firimu rakazara uye rakafanana rinopfuura pamusoro, rinowedzera kunaka kwechinhu uye kuramba kwecorrosion, uye kuwedzera hupenyu hwesimbi isina tsvina.
Usati washandisa simbi isina simbi yekunhonga uye passivation solution pazvikamu zvakasungwa, nzvimbo yesimbi isina tsvina inoda kucheneswa, kubviswa kwetsvina, uye kukwenenzverwa.Zvadaro, dururirapassivation solutionpinda mumudziyo wepurasitiki uye uishandise maererano nezvinhu zvesimbi isina tsvina uye kuoma kwe oxidation.Isa maworkpieces mumhinduro, kazhinji patembiricha yekamuri, uye inomesa kwemaminetsi mashanu kusvika makumi maviri kana kupfuura (nguva chaiyo uye tembiricha inotarwa nemushandisi zvichienderana nezvavanoda).Bvisa ma workpieces mushure mekubviswa kwakakwana kwekusvibiswa kwepamusoro, apo nzvimbo yacho inoratidzika zvakafanana nesirivha-chena.Mushure me pickling uyepassivation, simbura ma workpieces zvakakwana nemvura yakachena uye woomesa.
