Plating enhances resistance to leadscrew corrosion

Plating is the general name of surface-covering techniques in which a metal is deposited onto a conductive surface. Plating is indispensable as a corrosion inhibitor. for the manufacture of computers, mobile phones, and electronic devices as well as other uses such as solderability, hardness, wearability, friction loss, paint adhesion, conductivity, shielding, etc.

Electroplating

Electroplating is the process by which a metal in its ionic form is supplied with electrons to form a non-ionic coating on a desired substrate. The most common system involves: a chemical solution which contains the ionic form of the metal, an anode (positively charged) which may consist of the metal being plated (a soluble anode) or an insoluble anode (usually carbon, platinum, titanium, lead, or steel), and finally, a cathode (negatively charged) where electrons are supplied to produce a film of non-ionic metal.

Zinc Plating

Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not cause a breakdown of the substrate's surface integrity as it is formed. Indeed the zinc oxide, if undisturbed, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminum and stainless steels by their oxide layers.

Note: The type and material of plating will vary according to your requirements.
