electroless plating meaning in Hindi

Examples

1. In different applications, electrolytic or electroless plating can have cost advantages.
2. There are many factors to consider in selection of either electrolytic or electroless plating methods.
3. It sounds like what is happening is slow corrosion of both metals in acid with some competing chemical plating ( this is electroless plating ).
4. The most common electroless plating method is electroless nickel plating, although silver, gold and copper layers can also be applied in this manner, as in the technique of Angel gilding.
5. Electroless plating, also known as chemical or auto-catalytic plating, is a non-galvanic plating method that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power.
6. As to your original question-this is electroless plating-usually to electrolessly plate with copper you would need a copper salt eg copper sulphate, is this case though it looks like the copper salt is beeing made'in situ'by reaction of the copper with the acid.
