Iyo yekugadzira nzira yekupisa dip galvanized layer ndiyo nzira yekugadzira iron-zinc alloy pakati pesimbi matrix uye yekunze yakachena zinc layer.Iyo yepamusoro ye workpiece inoumba iron-zinc alloy layer panguva yekupisa dip plating, kuitira kuti simbi uye yakachena zinc layer inyatsobatanidzwa.Maitiro emupumburu wakakura waya waya inogona kungotsanangurwa se: kana iyo simbi workpiece inonyudzwa mune yakanyungudutswa zingi mhinduro, yekutanga zingi uye α-iron (muviri-pakati) yakasimba kunyungudika inoumbwa pane iyo interface.Iyi ikristaro inoumbwa nesimbi yematrix iron yakanyungudutswa nemaatomu ezinc munzvimbo yakasimba.Maatomu maviri esimbi akasanganiswa, uye kukwezva kwegiravhiti pakati peatomu kudiki.
Naizvozvo, kana zinc yasvika pakuzara mukunyungudika kwakasimba, zvinhu zviviri zvezinc neatomu dzesimbi zvinoparadzirwa pamwe chete, uye maatomu ezinc anoparadzirwa mukati (kana kupinzwa mu) matrix yesimbi anotama mulatisi yematrix uye zvishoma nezvishoma anoumba. alloy ine iron, nepo simbi yakanyungudutswa mumvura yakanyungudutswa yezingi inoumba musanganiswa wesimbi FeZn13 ine zingi uye inonyura muzasi mehari inopisa yemarara, ndiko kuti, zinc slag.Kana iyo workpiece ichibviswa kubva kune zinc leaching solution, pamusoro peiyo yakachena zinc layer inoumbwa, iyo ine hexagonal crystal, uye simbi yayo haina kupfuura 0.003%.
Kupisa dip galvanizing, inozivikanwawo sekuti hot dip galvanizing, inzira yekuwana chekufukidzira chesimbi nekunyudza nhengo yesimbi mune yakanyungudutswa zinc solution.Nekukurumidza kuvandudzwa kweiyo-high-voltage transmission, yekufambisa uye kutaurirana, zvinodiwa zvekudzivirira zvezvikamu zvesimbi zviri kuramba zvichikwira, uye kudiwa kwekupisa-dip galvanizing kuri kuwedzera zvakare.Kazhinji ukobvu hwemagetsi emagetsi galvanized layer ndeye 5 ~ 15μm, uye hombe mupumburu wakabatiswa waya layer inowanzopfuura 35μm, kunyange kusvika 200μm.Kupisa dip galvanizing ine yakanaka yekuvharisa kugona, dense coating uye isina organic inclusions.
