E-coating vs. nano coating

e coating is a normal process that anyone follows to minimize oxidization, and around the world a lot of jewelers as well as manufacturers use it. Do any of you having a practice or an idea about nanocoating and its behavior (durability, wear & tear, about maintaining the surface polish)

Hi, Tharanga.

Nano coating really implies nothing except engineering the coating at a nano scale. Unfortunately, "nano coating" has become nothing but a buzzword. I have heard of silicate coatings, zirconium coatings, chromate coatings and other coatings all called "nano coatings". So there are no durability, wear and tear, or surface polish standards that can be said to characterize nano coatings.

Hi
If we do e-coating on top of brass, normal procedure is plate the brass in gold (Copper, nickel and gold)

As e coating will help to keep the luster for a certain extent (minimizing oxidization), any idea about transforming the brass into gold color without dipping in gold.

From the cost wise this will be wiser, Some sort of a gold color lacquer will help....Any idea?
