Semi-bright nickel plating is a very common type of nickel coating in the plating industry, which is intermediate between bright nickel and non-glossy (matte or dull nickel), and is intended to provide a surface coating that meets certain mechanical and industrial performance requirements while also having a certain aesthetic appeal. Typical characteristics of semi-bright nickel include a more uniformly smooth surface and a moderately light-reflective gloss, but not as highly reflective and mirror-like as bright nickel.
The luster of a semi-bright nickel layer results from the specific chemical components and operating conditions in the plating bath. Semi-bright plating solutions typically contain lower concentrations of brighteners and semi-bright nickel additives than bright nickel. These additives accelerate the co-deposition of nickel and create a smooth and slightly shiny surface. Gloss control also requires accurate control of current density, nickel salt concentration, pH and other process parameters such as temperature and agitation speed during plating.
Bigely semi-bright nickel plating additive Ni-331
1、Uniform plating layer with good brightness. Ni-331 can obtain nickel plating layer with good ductility, moderate brightness and good filler.
2、Good bonding of plating layer. The nickel plating layer using Ni-331 semi-bright nickel additive can pass the 100-g test, and after the bonding test, the plating layer will not warp or peel off.
3. Neutral salt spray test is more effective. When the thickness of nickel-plated layer is 8~11μm, there is no obvious change in the appearance of the plated layer after 24 hours of neutral salt spray test.
4, High current efficiency. With the increase of current density, the deposition of nickel layer speeds up, the current density increases from 1A/dm2 to 5A/dm2, the current efficiency stays above 95%, and the brightness and porosity of the plated layer basically remain the same.
