Electroplating and Electroless nickel plating

Electroless plating is additionally referred to as chemical plating it’s a non-galvanic plating methodology that involves many coincidental reactions in associate degree solution, that occur while not the utilization of external power. The reaction is accomplished once chemical element is discharged by a reducer, commonly metal and change, therefore manufacturing a electric charge on the surface of the half. The foremost common electroless plating methodology is electroless nickel plating, though silver, gold and copper layers may also be applied in this manner, as within the technique of Angel coating.

What is Electrolytic Plating?

Electroplating will be outlined because the deposit of an awfully skinny layer of metals “electrolytically” to a base metal to boost or amendment its look. Electroplating is finished associate degree exceedingly|in a very liquid resolution known as a solution, additionally called a “plating bath”. The plating bathtub could be a specially designed chemical bathtub that has the specified metal (i.e. silver, gold) dissolved as microscopic particles suspended in resolution.

The plating bathtub resolution is a semiconducting medium and utilizes a coffee DC voltage (direct current). The item that’s to be plated is submerged into the plating bathtub and a coffee voltage DC current is applied to the tub. Typically settled in the middle of the plating bathtub, the item that’s to be plated acts as a charged cathode. The charged anodes which will complete the DC circuit area unit rigorously positioned at the perimeters of the plating tank. an influence supply called a rectifier is employed to convert AC power to a rigorously regulated low voltage DC current.

What is Electroless Nickel Plating?

Electroless nickel plating may be a chemical reduction method that depends upon the {catalytic|chemical method|chemical change|chemical action} reduction process of nickel ions in AN solution (containing a chemical reducing agent) and therefore the sequent deposition of nickel metal while not the utilization of voltage. Attributable to its exceptional corrosion resistance and high hardness, the method finds a wide application on things like valves, pump elements etc., to boost the lifetime of elements exposed to severe conditions of service, particularly within the oil field and marine sector. With correct pretreatment sequence and correct method management, smart adhesion and glorious service performance is obtained from nut deposited on a large number of aluminiferous and non-metallic substrates.

Electroless Nickel Plating is that the deposition of a nickel-phosphorous alloy onto a metal substrate whiles not the utilization of AN electrical current. The electroless nickel plating method utilizes a contact action chemical process to deposit a reliable, repeatable coating of uniform thickness. This uniformity of deposit will, in some cases, eliminate the necessity for post-plate grinding.
