Film of environmental protection acting chromium eletroplates advantage of craft of nickel cobaltic iron

1, be able to bear or endure corrode sex: As a result of microcrystalline construction, alloy film is had be able to bear or endure admirably corrode sex, fasten in body of sodium chloride solution (in IS03768) of this alloy film be able to bear or endure corrode sex 2.6 times Yu Ge film.

, 2, wearability: Because Ni3Fe is mixed,NiC03 metal each other changes the sclerosis of content and produce tall wearability. The wearability of this alloy film 2 times Yu Ge film. Because alloy film coefficient of friction is small, have tall anti-wear properties.

3, the exterior: Through adjusting the nickel in alloy film is mixed the content of iron, can obtain the burnish that is similar to chromic layer and tonal.

4, hardness nickel base the hardness that the iron in solid solution and cobalt can increase alloy film and thermodynamic stability, this alloy has quite tall hardness, plating condition hardness can amount to 750-850Hv, be close to hardness of plating hard chromium.

5, moving cost is low, it is plating chromium about 2/3.

Acting chromium of nickel cobaltic iron eletroplates craft, do not contain chromic, cadmium, lead, mercury, it is to replace the new-style environmental protection that tervalent chromium and 6 price chromium eletroplate to eletroplate craft, this craft and additive can detect through SGS, amount to RoHS2002/95/ES standard requirement.

Acting chromic film is very stable in atmosphere, colour and lustre and the function that fight corrode can be rivalled with chromic layer, deep plating ability, voltaic efficiency, yuan Sheng of section report function and plating are chromic. Fluid of acting chromic plating does not contain poisonous material, accord with cleanness to produce a demand, after be being protected through electroanalysising, be able to bear or endure the thermal shock of 200 ℃ does not become angry.

Plating large capacity, plating large capacity can amount to 1500 micron; The surface is smooth and ablaze; Deposition rate is rapid, current density 5 / decimetre, plating fast for 60 micron / hour; Film has the tenacity with low good internal stress and exceedingly good deepness capacity; The 16 ～ that deepness ability is plating chromium 18 times.

This technology belongs to craft of technology of efficient and clean finishing, specific power consumption is low, without eletroplate mud arises, realized liquid waste 0 discharge. Its the largest window is discharged in Yu Ling, feebleminded bad news and cleanness are produced.
