Why GL Nautical Instrument can be weatherproof & tarnishproof? The usual nautical brass instrument will tarnish or corrode after some while exposure to element, especially on ship or boat. People have to polish or refinish it again and again to keep luster. The reason of tarnish or corrode is that the polished surface of the instrument is just coated by a lacquer, there are many tenuous holes in the film of lacquer, air and water can still touch the surface of brass through these holes and corrode instrument surface. This problem has put out many nautical instrument manufacturers for many years. The tarnishproof nautical instrument of Goodluck Company, has ultra-hard mirror finish which can stands up to tough outdoor conditions and the long time test, the instrument will never tarnish and always look like new after long-term exposure to the elements, even ocean weather condition. 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, has been applied to nautical instrument by the Goodluck Company, 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.
