What is Stainless Steel?

Stainless steel jewelry is kind of uniqe and special metal jewelry, delicate texture and resilience, and corrosion preventive, 

never turn black or allergic. It always maintain the original color under the ordinary temperature. Stainless steel jewelry 

are kept the same material from in to out, and it tests to say totally non-corroding via the artificial sweat body test. 

The charaters of stainless steel are normally say 

*Strong acid resistant



*Not allergic

*Shape resistence, strong, shiny. 

A totally non side-effect and eviromental jewelry.  

PVD Process

What is PVD coating?PVD is the abbreviation of Physical Vapor Deposition. It is a process carried out in high vacuum at temperatures between 150 and 500C

How does the PVD process work?

The high-purity, solid coating material (metals such as titanium, chromium and aluminium) is either evaporated by heat or by bombardment with ions (sputtering). At the same time, a reactive gas (e.g. nitrogen or a gas containing carbon) is introduced; it forms a compund with the metal vapour and is deposited on the tools or components as a thin, highly adherent coating. In order to abtain a uniform coating thickness, the parts are rotated at uniform speed about several axes. 

The properties of the coating (such as hardness, structure, chemical and temperature resistance, adhesion) can be accurately controlled. 

The PVD processes include arc evaporation, sputtering, ionplating, and enhanced sputtering.
