Ukuguquguquka kocingo kunye nokwandisa kulungile, kunokumelana noxinzelelo lomsebenzi womatshini, kwishishini lelizwe lethu lidlale indima ebaluleke kakhulu.Kukho iintlobo ezininzi zocingo lwentsimbi.Eyona nto ixhaphakileyo yintsimbi emnyama kunyeucingo lwentsimbi.Ukuxhatshazwa kwe-corrosion ye-coat yangaphandle kuphuculwe ngokufanelekileyo, kodwa i-phenomenon ye-corrosion crevice iya kufumaneka emva kokusetyenziswa kwexesha elide.
I-Crevice corrosion luhlobo lwe-corrosion kwindawo encinci, ngakumbi kwindawo efihliweyo, enokuthi yenze umjikelo okhohlakeleyo we-corrosion.Phantse yonke i-corrosion ye-crevice ingenzeka kwi-alloy yesinyithi, kunye negesi equlethe i-anionic esebenzayo ephakathi kwe-Z kulula ukubangela ukubola kwe-crevice, i-corrosion ye-crevice ivame ukwenzeka kwi-aperture ye-0.025 ukuya kwi-0.1 mm, ngenxa yokuba ixesha elide lihlangene, iintanda ziya kubakho. uthotho lokungcola, ludityaniswe nemekobume yangaphandle efumileyo yonakalisa ngokulula indawo yesikhewu incinci.
Ukuvezwa kwexesha elide kobu kungcola kuya kubangela inguqu kunye ne-gap corrosion.Isisombululo esithe ngqo kule nto kukuqinisa ukugquma kwezinto eziphathekayo ukuphepha ukubola.Ubude bexesha lokukhusela ucingo lwentsimbi luhambelana kakhulu nobukhulu bengubo.Ngokuqhelekileyo, kwirhasi eyomileyo engundoqo kunye nokusetyenziswa kwangaphakathi, nakwiimeko ezirhabaxa zokusingqongileyo, ubungqingqwa bomaleko wegalvanized kufuneka buphakame kakhulu.Ke ngoko, ekukhethweni kobungqingqwa bomaleko owenziwe igalvanized ukuqwalasela impembelelo yokusingqongileyo.
Emva kokunyangwa kwe-galvanized layer, ifilimu eqaqambileyo kunye nenhle yombala we-passivation inokuveliswa, enokuphucula kakhulu ukusebenza kwayo kokukhusela kunye nokusebenza ngokukhawuleza.Kukho iintlobo ezininzi zezisombululo ze-zinc plating, ezinokuthi zohlulwe zibe yi-cyanide plating isisombululo kunye nesisombululo sasimahla se-cyanide ngokweempawu zabo.Isisombululo se-cyanide zinc plating sinamandla okusasaza kunye nobuchule bokugquma, icrystallization yokwambathisa igudile kwaye icokisekile, umsebenzi ulula, uluhlu lwezicelo lubanzi, kwaye sele lusetyenziswe kwimveliso ixesha elide.Nangona kunjalo, njengoko isisombululo se-plating sine-cyanide enetyhefu kakhulu, igesi ephumayo kwinkqubo yokucoca iyingozi kwimpilo yabasebenzi, ngoko ke amanzi amdaka kufuneka aphathwe ngokungqongqo ngaphambi kokuba akhululwe.
