Nicel haearn aloi electroplatio ateb ar gyfer trydan gwresogi tiwbiau

Yn ddiweddar, y prisiau o metelau deunyddiau wedi skyrocketed, gyda nicel bod y rhan fwyaf pwysig. Y electroplatio diwydiant fabwysiadwyd amrywiol mesurau i arbed nicel ailosod nicel nicel prisiau. Yn y 1980s, y hyrwyddiad o nicel aloi aloi electroplatio proses yn Tsieina% 27s electroplatio diwydiant yn llwyddiannus% 2c gyda A llwyddiant cyfradd o 1-51}. Nickel haearn aloi wedi ardderchog cyrydu ymwrthedd a addurniadol eiddo, a can arbed 10 y cant y cant nicel. Y platio ateb is sefydlog cynnal a chadw yn anodd. Yn anffodus, bell bell, o'r fath proses llwyddiannus has nid wedi digonol sylw o y electroplatio diwydiant, a nid wedi bod yn eang gymhwyso.

There are easily oxidized divalent iron ions in nickel iron alloy electroplating solutions, which are easily oxidized by hydrogen peroxide, potassium permanganate, hexavalent chromium, and air to form trivalent iron ions. Trivalent iron ions are easily converted into iron hydroxide, which can cause burrs in the coating. This can be seen from the p-pH diagram of Fe-H20. When pH=3, Fe3 plus will generate iron hydroxide precipitate, while Fez plus will not generate ferrous hydroxide precipitate until pH 27. So when electroplating nickel iron alloy, only the cathode is moved without air stirring. Nickel iron alloy electroplating is mainly used for hanging plating, because during barrel plating, especially when using a semi immersed drum, the rotation of the drum carries air into the plating solution, causing divalent iron ions to oxidize into trivalent iron ions, making maintenance of the plating solution difficult. Therefore, so far, there have been few reports on the barrel plating process of nickel iron alloy.

Mae hyn erthygl cynigion a newydd proses ar gyfer casgen platio nicel haearn aloi. Mae hyn broses goresgyn y problem o y platio ateb y cylchdro y drwm i oxidize divalent haearn ïonau. Mae'n nid yn unig arbed drud nicel metel, ond hefyd wedi y manteision o sefydlog platio ateb a hawdd cynnal a chadw.2c sydd is gwerth promoting vigorously.
