Chrome plating or chromium plating is an electrolytic technique for storing a thing layer of chromium over a metal or plastic article. Chrome plating is predominantly utilized for brightening reason, giving the substrate a tasteful look. Chrome plating is less expensive and choice to nickel plating regarding giving enrichment. Chromed surface give erosion opposition, expanded surface hardness, simple cleaning of parts, and so on.

Stores can be connected from 0.25 - 1,000 microns thickness for a wide scope of uses. The more slender stores being utilized to considerably expand the life of segments in wear applications or destructive conditions, and the thicker stores being utilized for rescue and fix of worn, harmed or mis-machined parts. Hard Chrome is classed as a "Chilly" process, the working temperature of 50 - 60°C guarantees no hindering impacts to the physical or mechanical properties of the base materials. Hard Chrome can be kept effectively and profitably onto most metallic substrate materials.

Advantages of Chrome Plating

• High Hardness: Electro-deposited Chrome is extremely hard, with typical values of 850 - 1050 HV (63 - 70 HRc), hence the term "Hard" Chrome. This makes it an excellent coating for wear resistant and abrasion resistant applications such as Moulds and Dies, Punches, Bearing and Seal surfaces, and sliding components.
• Low Coefficient of fricton: Hard Chrome has a very low coefficient of friction, approx. one half that of Steel. The coefficient against Steel of 0.16 lubricated (0.21 dry), makes it ideally suited for such applications as Bearing and Seal surfaces, and machinery components.
• Wear Resistance: The high hardness and low frictional properties of Hard Chrome provide it with extremely good resistance to abrasive and erosive wear, extending the life of components such as Moulds, Dies and Punches etc, up to ten times in most cases.
• Corrosion Resistance: Hard Chrome has an extremely high resistance to atmospheric oxidation, and a good resistance to most oxidising and reducing agents.(with the exception to Chlorides and other Halides), hence its wide-spread use in the Food and Chemical Industries.
• Sacrificial Wear Layer: Since Hard Chrome deposits are readily removed with chemical strippers, without detrimental effect to the base material, the part can be stripped and re-plated repeatedly, when wear shows, without loss or damage to the base part. This is a significant advantage for high wear, high cost parts such as Plastic Moulds and Dies where abrasive filled plastics are used.
• Machining: Hard Chrome deposits can be successfully finished by grinding, linishing or polishing.

 

Applications of Chrome Plating

Bumpers, rims, exhaust pipes and trim. It is also used for bright work on bicycles and luxury motorcycles. Other applications include hand tool and household items such as lighting and plumbing fixtures, wire racks, firearms, and appliances.
