Our stainless steel jewelry undergoes three types of electroplating processes: PVD vacuum plating, ion plating (IP), and water electroplating. Vacuum plating, also known as physical vapor deposition (PVD), is a surface treatment technology. This process involves evaporating or sputtering metal or non-metal materials under vacuum conditions and depositing them onto the surface of the object to create a thin film. PVD technology includes various coating methods, with ion plating (IP) being one of them. Ion plating (IP) is a physical vapor deposition (PVD) process that is sometimes called ion assisted deposition (IAD) or ion vapor deposition (IVD) and is a modified version of vacuum deposition.
The thickness of the plating layer is influenced by the electroplating process and duration. The longer the plating time, the thicker the layer becomes, resulting in longer color preservation.
Below is a brief comparison of the color durability of Ion Plating, PVD Vacuum Plating, and Water Galvanization.
| Electroplating Process | Feature | Metal Color | Color Durability |
|---|---|---|---|
| No Electroplating | Stainless steel is a non-reactive metal, which means it does not oxidize or tarnish like other metals such as silver or brass. Hypoallergenic. | Stainless Steel Color | Tarnish resistant, retain its color for a long time |
| Vacuum Ion Plating(IP) | The vacuum plating process is complex and requires specific environmental and equipment conditions, making it a green, environmentally friendly technology. The plating is done in a vacuum oven, resulting in longer color retention and a durable coating. |
