Inkqubo yokwakheka kwediphu eshushu yomaleko yinkqubo yokwenza i-iron-zinc alloy phakathi kwe-iron matrix kunye ne-zinc ecocekileyo yangaphandle.Umphezulu we-workpiece wenza i-iron-zinc alloy layer ngexesha lokutshisa idiphu, ukwenzela ukuba i-iron kunye ne-zinc ecocekileyo idibaniswe kakuhle.Inkqubo yocingo olukhulu oluyizinki lunokuchazwa nje ngokuba: xa i-workpiece yentsimbi intywiliselwa kwisisombululo se-zinc etyhidiweyo, i-zinc yokuqala kunye ne-α-iron (ephakathi komzimba) i-melt eqinile yenziwa kwi-interface.Le yikristale eyenziwe yintsimbi ye-matrix yentsimbi enyibilikisiweyo kunye ne-athomu ye-zinc kwimeko eqinileyo.Iiathom ezimbini zesinyithi zidibene enye kwenye, kwaye umtsalane womxhuzulane phakathi kweeathom umncinci.
Ke ngoko, xa i-zinc ifikelela kwi-saturation kwinyibilika eqinileyo, izinto ezimbini ze-zinc kunye ne-athom zentsimbi ziyasasazeka enye kwenye, kwaye iiathom ze-zinc zisasazeke kwi (okanye zingene) kwi-matrix yentsimbi ifuduka kwiletisi ye-matrix kwaye ngokuthe ngcembe yenze ukwakheka. i-alloy enentsimbi, ngelixa i-iron isasazeke kwi-zinc liquid yenza i-intermetallic compound FeZn13 kunye ne-zinc kwaye izika ngaphantsi kwembiza eshushu ye-galvanized, oko kukuthi, i-zinc slag.Xa i-workpiece isusiwe kwisisombululo se-zinc leaching, umgangatho woluhlu olucocekileyo lwe-zinc lwenziwa, oluyi-crystal ene-hexagonal, kwaye umxholo wayo wentsimbi awukho ngaphezu kwe-0.003%.
I-Hot dip galvanizing, ekwabizwa ngokuba yi-hot dip galvanizing, yindlela yokufumana isigqubuthelo sesinyithi ngokuntywilisela ilungu lentsimbi kwisisombululo se-zinc esityhidiweyo.Ngophuhliso olukhawulezayo lwe-high-voltage transmission, ukuthutha kunye nokunxibelelana, iimfuno zokukhusela iinxalenye zentsimbi ziba phezulu kwaye ziphezulu, kwaye imfuno ye-galvanizing eshushu-dip iyanda.Ngokuqhelekileyo ubukhulu bomaleko wegalvanized yombane yi-5 ~ 15μm, kwaye umaleko omkhulu wocingo owenziwe yizinki ungaphezulu kwe-35μm, ukuya kuthi ga kwi-200μm.Idiphu eshushu ye-galvanizing inamandla okugquma kakuhle, i-coat eshinyeneyo kwaye akukho ziquko zendalo.
