What is TiAlN coating?

What is TiAlN coating?

Aluminum Titanium Nitride (AlTiN) or Titanium Aluminum Nitride (TiAlN) is a thin film coating that was developed from Titanium Nitride. It is primarily used in high temperature environments above the limits of TiN usage. This coating works by forming a thin surface layer of Alumina (Al2O3), or Aluminum Oxide ceramic.

How does TiN coating work?

Titanium nitride (TiN) coating is wear resistant, inert and reduces friction. Medical device manufacturers use TiN coating to reduce galling between sliding components, help retain sharp edges on surgical instruments, and differentiate their products from the competition.

What color is TiAlN coating?

TITANIUM ALUMINUM NITRIDE (TiALN) TiAlN has a coating thickness of 1 to 3 microns and is typically violet-grey in colour.

What is AlTiN coating good for?

For which applications is AlTiN coating suitable? The highly aluminium-containing coating is very well suited for precision tools, that cut hard materials like e.g. steel (N/mm²) <1,300, stainless steel and cast iron.

How hard is tin coating?

Characteristics. TiN has a Vickers hardness of 1800–2100, 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 oxidize at 800 °C in a normal atmosphere. TiN has a brown color, and appears gold when applied as a coating.

Why tin is used for coating?

Tin is a relatively low cost coating material, and is thus very popular in the automotive industry. It can be applied by hot dipping, electroplating, and cladding. Due to its low melting temperature, it is an easily solderable coating, which makes it a versatile material.

What color is AlTiN coating?

violet black
AlTiN Aluminum Titanium Nitride Coating The oxidation onset temperature is 900°C, which is one of the highest commercially available oxidation temperatures for a PVD coating. RobbJack’s AlTiN coating has a violet black color and its hardness properties can be tailored by varying the aluminum content of the coating.

Is AlTiN coating good for cutting aluminum?

AlTiN Nano Superior results, extended tool life, and reduced cycle times over traditional AlTiN coatings in demanding applications where setup minimizes runout and vibration. Not recommended for use in aluminum and aluminum alloys.
