E ngotsoe ka 2015-11-16Ka lipatlisiso tse ling, batho ba hlokomela hore theknoloji ea dacromet ha e na theknoloji e tala ebile e se na tšilafalo, ho na le mathata a mang.
1. Bothata ba tšilafalo: Tharollo ea Dacromet ea dikahare tsa chromic acid e phahame haholo, nakong ea ho lokisoa le ho sebelisoa ha batho ba tla kopana le eona ka mokhoa o ke keng oa qojoa, ho sebelisa lijana le lisebelisoa li tla silafatsoa, ho kena filimi pele ho nako. tshebetso, e tla ke keng qojoa le mouoane oa mouoane oa metsi (ho tloha chromium plating phihlelo ho), kahoo lokiselitsoeng ho tloha tharollo ho hlahisa barbotage tshebetso ho etsa ha ho khase, mokelikeli le tiileng kotsi mesi e mesi e thata haholo, kapa tshireletso ya tikoloho thepa letsete le leholo haholo. .Hape, ha kutu ea ho roala e boetse e na le tšenyo ea Dacromet, li-chromium tse tšeletseng ka filimi ea ho roala li tla lokolloa.Hexavalent chromium ho chefo ea batho le carcinogenicity li matla haholo, hajoale linaha tse ngata tsa hexavalent chromium li na le moeli o thata oa litekanyetso ebile li thibela tšebeliso ea.Ka hona, e fetohile mokoallo o ke keng oa hlōloa ho Dacromet.
2.Mocheso o phahameng oa sintering, tšebeliso e kholo ea matla.
3.Bothata ba holim'a metsi le ho hanyetsa ho roala ha ho molemo, ho ntse ho e-na le mathata a likhokahano tsa galvanic corrosion le litšepe tse sa tšoaneng, tse amang boleng ba holim'a sehlahisoa le ts'ebetso ea anti-corrosion.
