Thin layer of chromium electroplating applied to a metal surface, typically between 0.5 to 5 microns thick.
The process is also carried out in a chromic acid electroplating bath using a short duration flash of current
It produces a good surfaced finish, corrosive protected and an visually improved aesthetic metal surface
Key Properties:
Hardness: It produces a surface hardness which lies in the range of around 800 to 1000HV ( Vickers Hardness). It adds a thin but, hard and scratch-resistant layer, improving the surface durability compared to bare metal.
Low coefficient of Friction: It reduces surface friction, improving lubricity and sliding performance for mechanical parts. Also, it’s very beneficial in light-duty applications such as pistons, rods and dies.
Corrosion Resistance: It forms a stable oxide film that protects the underlying metal from rust and oxidation. Also, it provides good resistance to moisture, chemicals and mild abrasion.
Bright Reflective Appearance: Mirror-like silver finish, often used for decorative and aesthetic purposes. Also, it maintains a high gloss and luster over time.
Applications:
Automotive Industry ( Trims, mirrors, interior fittings, piston rings and valves)
Aerospace ( Hydraulic rods, actuators and landing gear components)
Tooling and Molding Industries ( Injection molds, dies and forming tools)
Manufacturing and Machinery ( Shafts, rollers and cylinders)
Consumer Goods and Hardware ( Taps, Faucets, Handles and Decorative Fixtures)
Marine and Offshore Equipment ( Marine shafts, valves and fasteners)
