WHAT IS BLACK ZINC PLATED ?
Black Zinc Plating refers to the color of the chromate that is applied during the post plating process. It includes a layer of zinc applied to a parts surface followed by black chromate applied over the zinc.
Black Zinc is commonly specified for its dark appearance and protective properties. Black chromate offers additional corrosion protection by protecting the zinc plating and also provides a dark to deep black appearance depending on the surface condition of the part.
SO WHY SHOULD BLACK GALVANIZING?
The black galvanizing technology is widely used for protecting machine parts, metals. In addition, it also protects metal by electrochemical pathway of anot mechanism. When the phenomenon is corroded, because zinc has a negative voltage, it will be melted to protect the metal safe until the coating is very thin.
BLACK ZINC PLATING PROCESS
1. Durable processing of metal: smoothed and glossy by machining methods such as grinding, grinding, and other…
2. Grease Remover: A solvent that cleans the dirt and grease and sticks after machining.
3. Rinse: Before proceeding to galvanizing material we need to rinse material with water.
4. Conducting black zinc plating: Also conducting electroplating, the metal surface is coated with a black coating and undergoing passive chromium phase.
Passive chromium: A layer of zinc galvanization is usually 8 microns that are degassed, after deposition and black fumigation are carried out on the galvanized layer. The passive is like a durable transformation and there is no additional coating.
APPLICATION OF BLACK GALVANIZED
Black zinc plating apply very common in automotive industry. With corrosion resistance and the most effective benefit from galvanizing because it can help those details to be plated on vehicles that are longer and assume the cost of repair linked to corrosion. In addition, black zinc plating is using in other industries like : electronic, heavy truck and some aspects of social as well as
