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 nhazi na-adịkarị gburugburu 300 Celsius. Ihe mkpuchi a bụ nke gụnyere ultrafine flaky zinc, aluminum na chromium, nke nwere ike imeziwanye nguzogide corrosion nke ngwaahịa metal 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 flake zinc na aluminom, ọ na-egbochi mgbasa ozi na-emebi emebi dị ka mmiri na oxygen ịkpọtụrụ akụkụ ígwè. N'otu oge ahụ, n'oge nhazi Dacromet , chromic acid na-emeghachi omume na zinc, ntụ ntụ aluminum na metal base iji mepụta nnukwu ihe nkiri passivation, nke nwere ezigbo nguzogide 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 skru na ihe nkedo. 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.
