Electroplating Overview
I-Electroplating yinkqubo yokwaleka umaleko obhityileyo wezinye isinyithi okanye ialloys kumphezulu wesinyithi okanye ezinye izinto kusetyenziswa umgaqo we-electrolysis.. Inkqubo ye-electroplating idlala indima ekukhuseleni i-oxidation yensimbi (ezifana nomhlwa), ukuphucula ukumelana nokunxiba, conductivity yombane, ukukhanya, ukumelana nomhlwa (isulfate yobhedu, njl.), kunye ne-aesthetics yamalungu. Amaleko angaphandle eengqekembe ezininzi nawo acandiwe.
Iileyile ze-Electroplating zincinci ngokubanzi, ukusuka kwiimicrons ezimbalwa ukuya kumashumi eemicrons. Ngokusebenzisa i-electroplating, Ukhuselo lokuhombisa kunye nemigangatho eyahlukeneyo yokusebenza komhlaba inokufumaneka kwiimveliso zoomatshini, kunye neendawo ezigugileyo nezitshintshwe ngoomatshini ngokungachanekanga nazo zinokulungiswa.
Inkqubo ye-Electroplating
Ngokusisiseko ngolu hlobo lulandelayo:
(1) Xhuma intsimbi yokugubungela kwi-anode, okanye wongeze ityuwa enyibilikayo yentsimbi yokugquma kwindawo yokuhlambela;
(2) Into ekufuneka ifakwe idityaniswe kwi-cathode;
(3) I-cathode kunye ne-anode zidibaniswe nesisombululo se-electrolyte esakhiwe ngee-ion ezintle zentsimbi yokugubungela;
(4) Emva kokusetyenziswa kombane weDC, isinyithi se-anode siya kukhupha ii-electron, kunye ne-positive (intsimbi) iiyoni ezivelisa i-ion zetsimbi kwisisombululo se-electroplating ziyancipha (ii-electron zifunyenwe) kwi-cathode ibe yi-athomu kwaye iqokelelwe kumphezulu we-cathode (bona umfanekiso ongezantsi). ).
Iimfuno ezahlukeneyo ze-Electroplating kunye neMisebenzi
(1) Ukufakwa kobhedu: isetyenziswe njenge-primer ukuphucula ukunamathela kunye nokumelana nokubola kwe-electroplating layer. Ubhedu lula oxidized, kwaye emva kwe-oxidation, i-verdigris ayisakwazi ukuqhuba umbane.
(2) I-Nickel plating: isetyenziswe njenge-primer okanye njengembonakalo yokuphucula ukuxhathisa ukubola kunye nokuxhatshazwa kokugqoka. Ukumelana nokunxiba kwe-nickel plating kwiinkqubo zanamhlanje kudlula i-chrome plating. Qaphela ukuba iimveliso ezininzi ze-elektroniki azisasebenzisi nickel njengesiseko, ikakhulu ngenxa yokuba nickel ngumagnetic, okuya kuchaphazela i-intermodulation ye-passive ekusebenzeni kombane.
(3) Ukucwenga kwesilivere: Ukongeza ukuhlobisa, inokuphucula ukuchasana koqhagamshelwano lwezinto eziphathekayo. Isilivere ineempawu ezingcono, kulula ukufakwa kwi-oxidize, kwaye iqhuba umbane emva kwe-oxidation.
(4) Ukufakwa kwePalladium: I-nickel inokubangela i-dermatitis. The European Union has long rejected the import of nickel-containing jewelry. Palladium is the best nickel-substituting metal. Palladium is a rare, lustrous silver-white metal, a type of precious metal that is a hundred times more expensive than nickel. Because palladium is expensive, only thin palladium electroplating is generally used in China, with a thickness of 0.1~0.2μm, which is used as an anti-corrosion decorative coating and an anti-silver discoloration layer on cupronickel tin. If the palladium layer is too thick (more than 1 μm), cracks are prone to occur.
(5) Gold plating: The real gold component, in addition to decoration, can also improve electrical conductivity. Although gold is the most stable chemically, it is also the most expensive.
(6) Rose gold plating: reddish gold, eye yathandwa kakhulu kwizacholo zabasetyhini kwiminyaka yakutshanje. Igolide eRose ngokwenene yongeza ubhedu kwigolide, ukwenza igolide ibebomvu kancinci. Njengoko kubonisiwe kulo mfanekiso ungezantsi, uthelekiso lombala we 4 iintlobo ze-zinc ialloy esebenzayo yokucwenga ibonisiwe.
(7) Ukuxelisa igolide / ukuxelisa igolide yegolide: Ngenxa yokuba ixabiso legolide legolide liphezulu kakhulu, Igolide yokulinganisa iye yavela kwimarike, ukuze iimveliso ezinamaxabiso aphantsi zikwazi ukufikelela umbala wegolide.Ukuxelisa igolide ngokwenene lubhedu nje, hayi igolide. Ubhedu lula ukuba oxidized, ngoko ke umaleko okhuselayo kufuneka ugqunywe kumlinganiso weplating yegolide, kunye nevanishi (Ilacquer) isetyenziswa ngokubanzi. Ukulinganisa igolide yegolide kukutyalwa kobhedu ngevanishi. I-Varnish luhlobo lwepeyinti yeglue. Emva kokuba i-workpiece ipeyintiwe, imvakalelo ayilunganga njengaleyo yegolide yokwenyani, kodwa iindleko kunye nexabiso zinokuncitshiswa kakhulu.
