Vacuum / Ion Plating:
Vacuum/Ion Plating is more durable and wear-resistant than traditional plating methods. Additionally, its great advantage is environmental consciousness as it avoids chemical solution during the process and it’s irritation-free for the skin. Vacuum/Ion Plating is an advanced technique normally in the watch, electronic and space industries. The object is placed in a vacuum chamber, which is pumped down to the desired vacuum pressure. The chamber is then heated to the target temperature to evaporate the material, which is sprayed onto the object, producing a thin layer of coating.
Black coating uses either ruthenium or TIN cobalt black to give a piece of jewelry a light black or completely black appearance. It is very durable and resistant to scratches. Black plating gives the jewelry piece a sense of masculinity and high-tech.
