Part 1: Gịnị bụ electroplating?

Electroplating na-eji ọkụ eletrik eme ka ion metal ghọọ ihe mkpuchi dị mkpa ma dị nro nke ọla n'elu. Nke a nwere ike ime ka akụkụ ahụ dị ike, chebe ya pụọ ​​na nchara na iyi, ma melite ọdịdị ya. Zinc plating, nickel plating, na chrome plating bụ ihe niile ọkọlọtọ electroplating usoro.

Nkebi 2: Gịnị bụ galvanizing

Galvanizing bụ usoro nchebe nke na-eji akwa zinc kpuchie elu igwe iji kwalite nguzogide corrosion. Ihe oyi akwa zinc na-arụ ọrụ dị ka ihe mgbochi, na-egbochi ikuku na mmiri ịbanye na ígwè ma mee ka nchara. Ọbụna ma ọ bụrụ na oyi akwa zinc mebiri emebi, ọ ga-ebu ụzọ oxidize, na-echebe metal dị n'okpuru site na mmebi.

E nwere ụdị isi abụọ nke galvanizing: ọkụ-mikpu galvanizing na electroplating.

Galvanizing na-ekpo ọkụ bụ usoro nke itinye ígwè n'ime bat nke zinc dị ọkụ. Nke a na-emepụta akwa akwa zinc nke na-enyere aka igbochi nchara. A na-ejikarị ya eme ihe n'ụlọ dị n'èzí dị ka àkwà mmiri, ngere, na okporo osisi ọrụ.

Electroplating bụ usoro itinye akwa zinc n'elu igwe site na usoro electrochemical. Nke a na-emepụta elu dị larịị, na-egbuke egbuke nke dị mma maka ngwaahịa ndị chọrọ ọdịdị mara mma, dị ka obere ngwaike na ngwa ngwa.

Na-acha anụnụ anụnụ galvanizing anyị na-ahụkarị na kposara na mkpụrụ ọ bụghị nanị na mma ha ọdịdị na a na-egbuke egbuke, ubé bluish silver imecha, ma ọ na-enyere aka igbochi nchara, na-eme ka ọ ma na-echebe na anya na-adọrọ mmasị.

Nkebi nke 3: Gịnị bụ Nickel Plating

Nickel bụ ọla na-egbukepụ egbukepụ, na-egbuke egbuke. A na-arụzu nickel plating site na usoro electrochemical nke a na-etinye ion nickel n'elu akụkụ. A na-etinye akụkụ ahụ, na-arụ ọrụ dị ka cathode, na ngwọta nwere nnu nickel (dị ka nickel sulfate na nickel chloride) na onye na-ebelata ihe. Mgbe ọkụ eletrik na-agafe na ya, ions nickel na-esi na ngwọta ahụ gaa n'elu akụkụ ahụ, na-eme ka ọ dị nro, ọbụna mkpuchi nickel.

Ihe ịchọ mma nickel plating na-abụkarị oyi akwa dị gịrịgịrị (ihe dịka 5-15 microns) ma a na-ejikarị eme ya iji melite gloss na ọdịdị nke ngwaahịa ahụ. A na-ejikọta ya na chrome plating iji chọọ ihe ndị dị ka ngwa ụlọ na ngwa ngwa.

Mgbasa nickel nchebe ka ukwuu na-enyere aka melite nguzogide akụrụngwa na nchara, iyi na oxidation. A na-ejikarị ya eme ihe na akụrụngwa kemịkalụ, akụrụngwa akụrụngwa na ngwa n'èzí.

Kemịkalụ nickel plating anaghị achọ ọkụ eletrik wee mepụta akwa nickel n'elu site na mmeghachi omume kemịkal. Ihe mkpuchi ahụ bụ otu ma dị mma maka akụkụ ndị nwere ụdị mgbagwoju anya. Kemịkalụ nickel plating nwekwara ezigbo nguzogide corrosion na ike siri ike, a na-ejikwa ya na mbara igwe, ụgbọ ala, ngwa nkenke na mpaghara ndị ọzọ.

Nickel plating na-echebe megide nchara na iyi mgbe ọ na-enye ngwaahịa ahụ ọmarịcha mmecha. A na-ejikarị ya eme ihe na ngwaike, akụkụ eletrọnịkị, na akụrụngwa ụgbọ ala. Ihe mkpuchi nickel na-enweghị eletrọn dabara nke ọma maka akụkụ nwere ụdị dị mgbagwoju anya. Otú ọ dị, nickel plating dị oké ọnụ ahịa, karịsịa ihe ndị na-adịghị eletrọnịkị, na-achọkwa mkpofu pụrụ iche, nke nwere ike inwe mmetụta na gburugburu ebe obibi. Tụkwasị na nke ahụ, elu nke akụkụ ahụ kwesịrị ịdị ọcha ma dị mma, ma ọ bụghị ya, mkpuchi ahụ nwere ike ọ gaghị adabara nke ọma ma ọ bụ nke ọma.

Part 4 : Gịnị bụ Chrome plating
Chromium bụ ọla na-egbukepụ egbukepụ, na-acha ọcha na-acha anụnụ anụnụ nwere ntakịrị ntakịrị. A na-eme plating chromium site na usoro electrochemical nke a na-ebufe ion chromium site na ngwọta plating n'elu akụkụ ahụ. Akụkụ ahụ na-arụ ọrụ dị ka cathode na nnu chromium (dịka ihe ngwọta nke chromic acid na sulfuric acid) na-emebi n'okpuru ọrụ nke ọkụ eletrik, na-etinye akwa oyi akwa nke chromium n'elu. Nke a mkpuchi nwere magburu onwe eyi nguzogide, corrosion eguzogide, na aesthetics.
Enwere ike kewaa chrome plating ka ọ bụrụ chrome ịchọ mma na chrome siri ike.

A na-ejikarị chrome a na-achọ mma na-eme ka ọdịdị nke ngwaahịa ahụ dịkwuo mma ma na-enye ụfọdụ ọkwa nke nguzogide corrosion. Ihe mkpuchi ahụ dị gịrịgịrị (na-abụkarị 0,5 ruo 1 micron) ma na-etinyekarị ya dị ka oyi akwa dị n'elu elu nke nickel maka ihe ịchọ mma.

Ihe mkpuchi chrome siri ike dị oke (nke na-abụkarị 10 ruo 500 microns) ma na-enye ezigbo mgbochi iyi, obere esemokwu na ike siri ike. A na-ejikarị ha eme ihe iji gbasaa ndụ ọrụ nke akụkụ igwe dị ka mkpanaka hydraulic, pistons engine na ụdị mmepụta ihe.
Hexavalent chromium (Cr) bụ ụdị chromium kachasị emerụ ahụ ma bụrụkwa nke a ghọtara dị ka carcinogen mmadụ. Ihe mkpofu nke hexavalent chromium electroplating solution na-emepụta bụ ihe na-egbu egbu na a ga-agwọrịrị ya nke ọma tupu ahapụ ya.

Trivalent chromium (Cr 3+) emebere ya site na chromium sulfate ma ọ bụ chromium chloride ma nwee ike bụrụ ihe nchekwa dị mma na chromium hexavalent na ngwa na ọkpụrụkpụ ụfọdụ. Ọ dịkwa mma na gburugburu ebe obibi mana ọ chọrọ ijikwa nke ọma na mkpofu ya.
