Zinc Phosphate Coating
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc phosphates, to achieve corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. It is one of the most common types of conversion coating. The process is also called phosphate coating, phosphatization, phosphatizing, or phosphating.

Alkaline Zinc Nickel
Alkaline Zinc Nickel is an alloy composition of 12-15% nickel, with the remaining percentage made up of zinc. Following the addition of an acid coating during zinc nickel plating, this alloy has exceptional strength and corrosion resistance and can be easily passivated later on.
At Riverdale, we use the groundbreaking environmentally friendly Coventya Zinc/Nickel System (12-15% Ni). This is an extremely reliable process that provides for the direct plating on 410 Stainless Steel without the need for a “Flash Nickel Strike”, and also easily coats hard-to-plate Case Hardened parts.
This Zinc/Nickel plating system offers a bright, uniform finish, even in low current density areas, such as on clips, nails and stampings. Very even distribution of the plating deposit allows for long parts to be plated uniformly, unlike most other electroplating processes. With a 12 to 15% Nickel deposit, this system offers exceptional corrosion protection when used with passivates which are offered in clear or black.
