Zr: Zirconium 

It is a chemical element, its chemical symbol is Zr. Its atomic number is 40, is a high melting point metal, light gray.

The valence is + 2, + 3 and + 4. The first ionization energy is 6.84 ev.  The surface of zirconium is easy to form a layer of oxide film with luster,  so the appearance of zirconium is similar to that of steel.  It has corrosion resistance, soluble in hydrofluoric acid and aqua regia. At high temperature, it can react with non-metallic elements and many metal elements to form solid solution compounds

Zr&ZrN coating 

Alterna zirconium nitride based PVD coating is a coating type with low  surface friction co-efficient, high hardness and chemical stability. Due to  its these properties, it offers successful results especially in tools used  for machining of soft metals such as copper, brass, aluminum, stainless  steel, and in plastic injection molds. It is also successfully applied to gear knives used in well-cooled medium

Properties and application areas

1. High hardness and very low friction feature

2. It is suitable for surface coating of decorative materials that are easy to wear, like clothes zipper, door handle, switch, etc

3. Suitability for metal removal tools of non-ferrous soft metals

4. Excellent resistance to adhesive wear and adhesion wrapping wear
