Conversion Coating


Manganese phosphate coating is a popular phosphate coating due to its hardness and outstanding wear resistance. It is applied to the surface of ferrous substrates to prevent galling and to improve break-in properties. 

Phosphate coatings are used to pre-treat metal prior to coating or painting and to increase specific metal properties like corrosion resistance. The use of manganese phosphated coatings for improved corrosion resistance can be found in virtually all branches of the metal working-industry.

As matter of fact, Manganese Phosphate Anti-Gall Treatment is considered critical on all re-machined and new Rotary Shouldered Connections.

BRIGHT is the leading metal finishing and plating company in U.A.E, we offer manganese phosphate coating services that are perfect for engineering applications.

Phosphated Connections: They are darker and have a matte finish.

Hard Anodizing

Anodizing is a metal finishing process used to increase the thickness of the oxide layer on the surface of a substrate (Aluminium). The Aluminium oxide that is formed generally occupies more space than the base metal converted. The treated part forms an anode electrode that is used to complete an electrical circuit. The general benefits of anodization are similar to many of those provided by electroplating and include:

  • Increased corrosion resistance
  • Enhanced resistance to wear and tear
  • Improved surface hardness
  • Increased aesthetic appeal
  • Lengthened part/component lifespan

Hard coat anodizing uses a combination of relatively low plating bath temperature and constant rectification of the electrical current to develop an extremely hard oxide film coating. The coating can range from light to dark gray in color and can even be dyed black if desired. Hard coat anodizing provides substantial corrosion protection and wear resistance, along with excellent lubricity.

Layer thicknesses between 25 and 120 µm
