Abstract
In industrial applications, components can be coated using various methods.One of these methods which widely used
is electroplating.
The process is significantly cheaper, simple and complex surfaces can be coated uniformly because the thickness of films can be easily controlled.
Nickel alloys electrodeposition have increased recently because of its use in numerous application such as hardness
resistance to heat, wear corrosion and low abrasion coefficient.
Furthermore, electroplating of nickel alloys is particularly important in electronic memory device in computer& in
electronics industry.
The present work was devoted to develop new baths which are characterized by their cheapness in addition to their
non-polluted nature, which enable use to deposit sound and satisfactory Ni-P, Ni-P-Co, and Ni-W-P coatings.
In addition, to develop and improve the quality& performance of Ni-alloy coatings composite coatings are finding
increased uses Composite coatings are used to improve the hardness, wear, and corrosion resistance of metal surfaces for tools, bearing and machine parts. Therefore, this research work on electroplating of hard nickel alloys.
