It has more than tripled the heat and corrosion resistance to zinc-plating, and there is little generating of hydrogen embrittlement. It is mostly used to the autparts of which high heat and corrosion resistance is required.
A film which does not contain hexavalent chromate becomes possible by carrying out trivalent chromate
and performing Non-chromium coating on top coat as alternative treatment of hexavalent chromate.
Salt spray test:During 500 hours, less than 5% area of white color rust generating.
Since a film is hard and there are few wear coefficients, it has excellent wear resistance.
Application:Functional parts, such as a crankshaft.
It has uniform and graceful appearance and has high corrosion resistance.
Application:coating of auto parts.
Since tin is a comparatively soft metal, it plates to sliding surface of a machine and achieves the duty which improves familiarity. Moreover, it plates to things which carry out solder processing, such as electric parts, and the process ability of solder is improved or it is used for nitriding prevention etc.
There are the outstanding leveling and macrothrowing power.
Application:undercoat for decorative plating, preventing method for carburizing, electroforming.
In the color tone which has deep metallic luster, it is used as the last finish of all parts.
Application:Exterior parts(a head lamp, a taillight, and indicator etc.)
It is broadly used as plating to accessories, electronic products, etc.
The application, such as accessories, tableware, and electronic products, is used widely.
It is used for the decorative use as a golden imitation. Unlike brass plating, a color tone becomes very grace and near 24K Gold color and it has the corrosion resistance of the level which can be used as exterior parts.
There are corrosion resistance and heat resistance.
Application:optical instruments, ornament parts such as a muffler of a motorcycle, and a holder of a lens.
It is widely used for the place which needs good soldering, such as electricity and electronic products, a printed circuit board, auto parts, and a machine part.
It excels in wear resistance and uniform precipitation like electroless nickel-phosphorus plating. Moreover, compared with nickel-phosphorus plating, if there is no heat treatment, there is Hv700-800(Vickers hardness) in the state of a deposit.
It excels in the corrosion resistance, wear resistance, and uniform precipitation of a film.
Application:auto parts such as an inside of a pipe, a shaft, and a piston, and precision instruments such as a metallic mold.
With this processing, a powerful lubricant film is formed and it is useful to high life-zation of an edged tool etc.
Appearance can be freely controlled from the shape of satin to gloss, and the gloss side is very excellent.
Up to now, polycarbonate resin was adapted as for the headlight lens of automobiles
and motorcycles from the reason of design. However, wear resistance(easy to scratch)
and weathering resistance (discoloration by UV) are bad if it remains as it is.
In order to protect the surface, hard coating is performed.
