What are the different products of chromate conversion coating?

Related products include Iridite ®, TCP-HF, and Bonderite ®. Chromate conversion coatings are a type of chemical conversion coating. In chemical conversion coatings, the metal undergoes a chemical reaction at the surface. This chemical reaction transforms the metal surface into a protective layer.

What is the difference between chromate and no-chromate?

Chromate conversion coating for aluminum, contains hexavalent chromium. Resulting color is iridescent gold or yellow to tan. Chromate conversion coating for aluminum, contains hexavalent chromium. Resulting color is clear. No-Chromium (hexavalent or trivalent) alternative treatment for aluminum or magnesium.

What are the different types of chromates under MIL-DTL-5541?

MIL-DTL-5541 Types and Classes MIL-DTL-5541 Standard Type 1 Type 2 Chromates Hexavalent Chromate Hex-Free Chromate (Trivalent Chromate) Class 1A Maximum corrosion protection Maximum corrosion protection Class 3 Improved electrical conductivity with co Improved electrical conductivity with co

What are Chemic chemate conversion coatings?

CHROMATE CONVERSION COATINGS are formed on metal surfaces as a result of the chemical attack that occurs when a metal is im- mersed in or sprayed with an aqueous solution of chromic acid, chromium salts such as sodium or potassium chromate or dichromate, hydrofluoric acid or hydrofluoric acid salts, phosphoric acid,

What is chromate paint and how does it work?

Chromate treatments produce effective paint bonds through molecular adhesions with the film being bound to the metal, in turn offering the same type of adhesion to the organic coating. The film reduces creep corrosion, forming an effective barrier against corrosive attack through pores or scratches in the paint.

How many steps are involved in the chromating process?

Type 2 Chromating process (typically 5 steps): The Type 2 hex-free chem film surface conversion process with TCP-HF has 2 variations, Acid Clean and Alkaline Clean.
