Kunezinhlayiya eziqinile kusixazululo se-plating.Uma unqenqema kanye nethiphu yezingxenye kumaholoholo, kungenzeka ukuthi ukuminyana kwamanje kukhulu kakhulu.Uma iungqimba lukathayelakuhle, kodwa ekukhanyeni kwe-nitric acid engu-3%, i-coating inethunzi elimnyama, ifilimu ye-passivation ibonakala insundu, ingaba ithusi eliwuketshezi elinamandla noma umthofu nokunye ukungcola kwensimbi.Okokuqala hlola izinga lokushisa nokuminyana zamanje, bese ngokusebenzisa ukuhlaziywa okugeza, ukunquma futhi ulungise okuqukethwe zinc kanye sodium hydroxide okugeza, okuqukethwe DPE iphansi, kungaqondwa ngokusebenzisa hull tank test.
Uma enamathela emahhadlahhadla akuzona izizathu ezingenhla, kungase kubangelwe ukungcola isixazululo Plating, kungathatha inani elincane plating isixazululo, futhi ukuhlunga ngemva kokuhlolwa, bese uthatha inani elincane plating isixazululo, ukuhlola zinc powder kusetshenzwe. , hlola ukuthi ukwehluleka kuyizinhlayiya eziqinile noma ithusi, umthofu, nokunye ukungcola okuhlukile kwensimbi, into ngayinye, ukuhlolwa, akunzima ukuthola imbangela yokwehluleka.Ukususwa kukawoyela okungaphelele noma ukugqwala kwe-asidi kuzodalaucingo olukhulu lukathayelaukugqoka i-blister.
Kodwa isizathu esiyinhloko salolu hlobo lokugeza kulula ukubhubhula ukukhanyiswa kwezithasiselo eziphilayo endaweni yekristalu ye-coating, ukuze i-crystal yasekuqaleni noma enye indawo ye-crystal ingakwazi ukukhula ngokujwayelekile, okuholela ekuthuthukisweni okungavamile kwe-crystal nuclei entsha. noma i-crystal surface;Noma izithasiselo ze-organic kusiqeshana sokumboza, zivimbela ukuhlelwa okuvamile kwe-lattice, okuholela ekuhlanekeni kwe-lattice, ngaleyo ndlela kwandise ingcindezi yangaphakathi ye-coating, okuholela ekugwemeni kwe-coating.
