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.
For brazing titanium alloys. Available as amorphous foil. 17: Zr 83: Zr 56 V 28 Ti 16: 1193/1250 [5] – For brazing titanium alloys. Available as amorphous foil. 16: Zr 56 V 28: Ag 57 Cu 38 Ti 5: active 775/790 [5] – Active alloy. Can be used for brazing ceramics, e.g. silicon nitride. Titanium forms an interfacial layer with Si 3 N 4 ...
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]
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 ...
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]
A material with high stacking-fault energy, such as aluminium or titanium, will be far more susceptible to galling than materials with low stacking-fault energy, like copper, bronze, or gold. Conversely, materials with a hexagonal close packed (HCP) structure and a high c/a ratio, such as cobalt-based alloys, are extremely resistant to galling. [4]
Titanium-containing nickel-gold braze wets silicon nitride and reacts with its surface, forming titanium nitride and liberating silicon; silicon then forms brittle nickel silicides and eutectic gold-silicon phase; the resulting joint is weak and melts at much lower temperature than may be expected.
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 ...
