Prepared with an extremely robust, malleable, and bendable characteristic, deployment of cadmium plating has been ever increasing in huge industries such as aviation, defense, automotive, electronics, electrical and more. A number of off-shore engineering projects nowadays look for cad plating objects to attain lasting outcome in adverse salt-water surroundings. Industries that produce cad plating, as well as its users, are obligated to follow all precautionary measures as per federal rules owing to its noxious effect on nature mother.
Cadmium plating is predominantly applied for plating objects made of steel, cast iron or aluminum to gain resistive coat to corrosion for metal substrates used in alkaline, salty and its equivalent environmental settings. Cadmium, a zinc by-product and a great alternative of gold plating are globally distinguished for its ‘sacrificial coating’ feature that enables it to protect its underlying metal even being rusted or decayed.
Cadmium Plating - Process
Typically, industries follow electro-deposition procedure for cad plating on metal substrates through an electrolyte solution based containing cadmium salt in barrels, vat, or other means. Amidst all possibilities of plating solutions, alkaline cyanide has received due recognition with its reliability to add the desired features to things that are coated. On the passing of electric change via the solution, cadmium from anode end travels and starts depositing on target metal at the cathode part. For plating of high volume small components like bolts, clips, washers, springs, fasteners, chiefly vat plating is carried out by plating companies.
Cadmium Plating - Benefits
Superior Corrosion Resistance
Right from aerospace to defense, off-shore to shipping and automotive to electronics, almost all major industries look for cadmium plating services for products and metal parts that sit in extreme environmental atmosphere. Given that the spares like nut, bolts, clamps, or fasteners keep hold of the major framework, more and more industries prefer using cad plated tools for its brilliant anti-corrosive feature.
Needless to say, adhesiveness of metal substrates often appears critical in developing an airplane, structural engineering products, automotive and other industries. Innate adhesive quality of cad plating has been proven to be dependable, steady and enduring that makes it popular to industrial users.
Natural lubricity feature of cadmium plated objects are proven to be effective to deal with frictional galling possibilities, commonly occur in moving parts of machinery. As those metal surfaces are plated with cadmium, their lubricity facet discards the possibility of friction that prevents work speed and thus uplifts productivity.
The lustrous appearance of cad plating resembles gold plating or silver plating. In various industrial applications where aesthetic of product is in demand, cad plated materials are often demanded. It can also offer color options such as green, black, and olive.
