This technology allows for obtaining coatings with a thickness of up to 3 μm with low internal stresses, without cracks, in a matt milk colour with a delicate grey shade. The rhodium plating of silver and gold has been developed in a particular technology for technical applications such as reed switches.
Why is it worth doing this?
This method prevents jewellery or other elements from oxidising, turning the colour darker or even black. In addition, it makes the part appear brighter and therefore more attractive regardless of the original material. This also applies to gemstones.
We perform rhodium plating of gold directly on the material using the galvanic method when coating metals such as silver, copper and its alloys, nickel and its alloys, aluminium, a nickel and gold sublayer is required.
