N'oge a na-eji ya eme ihe, akụkụ ígwè na-adị mfe na electrochemical corrosion na chemical corrosion n'ihi mmetụta nke gburugburu ebe obibi. Ọ bụ ihe na-emekarị na ulo oru ngwa ka mma elu Njirimara nke workpieces site elu ọgwụgwọ technology na welie mgbochi corrosion Njirimara nke workpieces. Okwu a na-ewebata teknụzụ ihu abụọ nwere ezigbo mgbochi corrosion: teknụzụ ọgwụgwọ elu Dacromet

Nkà na ụzụ ọgwụgwọ elu Dacromet bụ teknụzụ mkpuchi corrosion, nke a na-ejikarị maka nchebe elu nke ngwaahịa ọla. Ọ na-eji usoro plating enweghị electroless kpuchie elu igwe na akwa mkpuchi inorganic nwere ihe mgbochi corrosion. Okpomọkụ a na-emekarị bụ ihe dị ka 300 Celsius. Ihe mkpuchi a bụ nke gụnyere ultrafine flaky zinc, aluminum na chromium, nke nwere ike imeziwanye nguzogide corrosion nke ngwaahịa ọla na ogologo ndụ ọrụ ha. Usoro Dacromet nwere ike ịmepụta oyi akwa ihe nkiri nke 4 ~ 8 μm n'elu ọrụ ahụ. N'ihi njupụta nke zinc flake na aluminom, ọ na-egbochi mgbasa ozi na-emebi emebi dị ka mmiri na oxygen ịkpọtụrụ akụkụ ígwè. N'otu oge ahụ, n'oge Dacromet nhazi , chromic acid kemịkalụ na-emeghachi omume na zinc, aluminom ntụ ntụ na isi metal na-emepụta ihe nkiri passivation siri ike, nke nwere ezigbo nkwụsị nke corrosion.

Na mkpokọta, teknụzụ ọgwụgwọ elu Dacromet bụ usoro ọgwụgwọ elu igwe a na-ahụkarị. A na-eji teknụzụ Dacromet eme ihe maka nchebe mgbochi corrosion, ọkachasị maka screws na fasteners. A na-ejikarị ya eme ihe iji melite ike na ịdịte aka nke ngwaahịa ọla. Abrasiveness na nguzogide corrosion. Maka ihe arụrụ arụ nke nwere ma isi ike yana ihe mgbochi corrosion chọrọ, teknụzụ Crow ka ọdabara. Mgbe ị na-ahọrọ teknụzụ ọgwụgwọ elu kwesịrị ekwesị, ọ dị mkpa ka a họrọ ya dịka ngwa ngwa chọrọ.
