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.
The fundamental reasons why TiAlN coatings outperform pure Titanium nitride (TiN) coatings are considered to be: Increased oxidation resistance at elevated temperatures due to the formation of a protective aluminium-oxide layer at the surface; Increased hardness in the freshly deposited films due to micro-structure changes and solid solution ...
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.
Titanium nitride coated twist bit. Many different materials are used for or on drill bits, depending on the required application. Many hard materials, such as carbides, are much more brittle than steel, and are far more subject to breaking, particularly if the drill is not held at a very constant angle to the workpiece; e.g., when hand-held.
The ACR "rifles" used smoothbore barrels to fire single or multiple flechettes (tiny darts), rather than bullets, per pull of the trigger, to provide long range, flat trajectory, and armor-piercing abilities. Just like kinetic-energy tank rounds, flechettes are too long and thin to be stabilized by rifling and perform best from a smoothbore barrel.

Why are the properties of titanium nitride on the german Wikipedia different from the english Wikipedia? (Molar mass 61.874 g/mol - Molare Masse 61,91 g·mol−1; Density 5.40 g/cm3 - Dichte 5,22 g·cm−3; Melting point 2930 °C - Schmelzpunkt 2950 °C) Volker; 10.08.2009
The original patent filed by Hermann Gerlich in 1932 [6]. The squeeze bore concept was first patented by German inventor Carl Puff in 1903 [7] [8], even though the general principle was known already in 19th century and later applied in lighter fashion on Armstrong guns, on which only the muzzle yet not the barrel itself was of slightly smaller diameter (to cast off the sealing leather-bag ...
