What happened on these instruments?
The ultimate solution is the revolution of surface treatment technology!
PVD-Coating, one of the most advanced surface treatment technology, and coat a Zirconium Nitride (ZrN) coating on her instrument surface. The ZrN coating has significantly highlights as follows:
* Significantly high corrosion resistance
* Decreased friction
* Extremely high wear resistance
* Increased lifespan
* Highly durable
* Shiny golden white color
For example, ZrN coating is often applied to artificial organ to protect its stainless steel parts to avoid corrode; and it is also the ultimate solution for valves that are intended for use in highly corrosive environment.
Tarnishproof Nautical Instrument, will be a product can shows its charms that will never fade without a letup.
