Rose Gold, a money-making genie for PVD decorative coaters

PVD Coating Rose Gold iPhone

Some time ago and partly still today, to obtain the appearance of the colour rose gold, the base material must be dipped in a mixture of gold and copper.

Involving gold is an expensive process, and even a small deviation in the gold and copper mixture could result in a completely different colour appearance, meaning different “L*’, “a*” and “b*” values.

Such a dipping process is very costly.

Every re-coating needs de-coating which subsequently results in the loss of the expensive raw material Gold.

Recently PVD - Physical Vapour Deposition - offers an excellent rose gold colour based either on sputtered Titanium / Zirconium or arc-evaporated in nitrogen and acetylene atmosphere.
