JLS is capable to produce carbide punch with varies coatings including titanium nitride coating.
What is Titanium Nitride? Titanium nitride (TiN) (known as tinite) is a super hard ceramic material, mainly used as a coating on tungsten carbide, titanium alloys, HSS, carbide, and aluminium components to improve surface properties.
Applied as a thin coating, Titanium Nitride is used to harden and protect cutting and sliding surfaces, for decorative purposes (due to its golden appearance), and as a non-toxic coating for medical implants. In most cases a coating of thinner than 5 micrometres (0.00020 in) is applied.
Properties
TiN has a hardness of 1800–2100 Vickers , a modulus of elasticity of 251 GPa, a thermal expansion coefficient of 9.35×10−6 K−1, and a superconducting transition temperature of 5.6 K.
TiN will oxygenate at 800℃ in a normal air. It is chemically stable at 20 °C, according to laboratory experiments, but can be slowly attacked by concentrated acid solutions with rising temperatures. According to the substrate and surface finish, TiN have a wear property ranging from 0.4 to 0.9 against another TiN surface (non-lubricated).
Usage
A known usage for TiN coating is corrosion resistance on machine tooling, such as punch tools, drill bits and milling cutters, often improving their lifetime.
