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.
Titanium nitride (TiN) is a refractory solid exhibiting extreme hardness, thermal/electrical conductivity, and a high melting point. [13] TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs scale), [14] and is often used to coat cutting tools, such as drill bits. [15]
1968 — Canadize is invented, a coating that augments surface hardness for titanium and titanium alloys. [3] 1969 — The first man walks on the Moon, and thanks to General Magnaplate he was able to drill into the Moon's surface. A Canadize treatment on both the inside and outside of the titanium core sample drill tubes prevented samples being ...
Osbornite is a naturally occurring variety of titanium nitride. It was first discovered in the Bustee meteorite in the late nineteenth century. [1] Its crystals are golden-yellow octahedrons, combined with oldhamite. It is friable and does not dissolve in acids. [2]

Many older Americans want to live out their lives in their own homes. Josie Norris /The Tennessean-USA TODAY NETWORK
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 ...
