Aluminium titanium nitride (AlTiN) coated endmills using cathodic arc deposition technique. Titanium aluminium nitride (TiAlN) or aluminium titanium nitride (AlTiN; for aluminium contents higher than 50%) is a group of metastable hard coatings consisting of nitrogen and the metallic elements aluminium and titanium.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Nitriding alloys are alloy steels with nitride-forming elements such as aluminum, chromium, molybdenum and titanium. In 2015, nitriding was used to generate a unique duplex microstructure in an iron-manganese alloy (martensite-austenite, austenite-ferrite), known to be associated with strongly enhanced mechanical properties.

Aluminium nitride (Al N) is a solid nitride of aluminium. It has a high thermal conductivity of up to 321 W/(m·K) [ 5 ] and is an electrical insulator. Its wurtzite phase (w-AlN) has a band gap of ~6 eV at room temperature and has a potential application in optoelectronics operating at deep ultraviolet frequencies.
The nitride anion, N 3-ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring. Some nitrides have a found applications, [1] such as wear-resistant coatings (e.g., titanium nitride, TiN), hard ceramic materials (e.g., silicon nitride, Si 3 N 4), and semiconductors (e.g., gallium nitride, GaN).
It has a chemical composition of 6% aluminum, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium. [19] It is significantly stronger than commercially pure titanium (grades 1-4) while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in ...
Five such coatings are TiN (titanium nitride), TiC (titanium carbide), Ti(C)N (titanium carbide-nitride), TiAlN (titanium aluminium nitride) and AlTiN (aluminium titanium nitride). (Newer coatings, known as DLC ( diamond-like carbon ) are beginning to surface, enabling the cutting power of diamond without the unwanted chemical reaction between ...
nitrides (simple — ZrN, TiN, AlN, CeN and others; compound — Nb(C, N), V(c, N) and others), which can be found in alloyed steel and has strong nitride-generative elements in its content: titanium, aluminium, vanadium, cerium and others; silicates
