Description
Technical field
The present invention relates to electroplating technology, in particular to a kind of method for electroplating steel and iron parts.
Background technology
Steel and iron parts generally for antirust it is wear-resisting can surface carry out electroplating processes, have high rigidity, excellent anti-wear performance,
Corrosion resistance and decorative surface, to improve the corrosion resistance of steel substrate, wearability, case hardness and dicoration.But current electricity
Electroplating method all need to be improved for the wearability and corrosion resistance of coating, therefore needs to study new electroplating surface processing method and electricity
Plating solution, the adhesion of coating and steel and iron parts is improved, strengthen the wearability and corrosion resistance of coating.
The content of the invention
It is an object of the invention to provide a kind of method for electroplating steel and iron parts, to solve the above problems.
To realize the object of the invention, the technical scheme that uses for：A kind of method for electroplating steel and iron parts, including herein below：
A. oil removing, derusting are carried out to steel and iron parts surface, cleans up and polishes；B. electroplate liquid is prepared, electroplate liquid includes following parts by weight
Component：20~30 parts of chromium sulfate, 10~20 parts of chromium chloride, 15~30 parts of boric acid, 5~8 parts of oxalates, sodium chloride 20~40
Part, 3~5 parts of amion acetic acid, 1~5 part of complexing agent, 1~5 part of complexant, 1~5 part of buffer, 1~5 part of ethane, deionized water
80~100 parts；C. electroplate liquid after 1~2 hour is stirred, steel and iron parts immerse electroplate liquid, and temperature of electroplating solution is 30~40 DEG C, during plating
Between be 15~40 minutes, workpiece is cleaned up with water after plating, dry up.
Further, the electroplate liquid includes the component of following parts by weight：25 parts of chromium sulfate, 15 parts of chromium chloride, boric acid 20
Part, 6 parts of oxalates, 30 parts of sodium chloride, 5 parts of amion acetic acid, 2 parts of complexing agent, 2 parts of complexant, 2 parts of buffer, 1 part of ethane, go
