Abstract
There is disclosed a titanium nitride doped with boron crystallizing with the same structure as titanium nitride TiN and having a Vickers microhardness greater than approximately 50 GPa. There is also disclosed an anti-wear coating comprising this titanium nitride doped with boron. There are also disclosed parts such as metal parts, tungsten carbide parts and cermet parts, for example, including a coating of this type.

Titanium nitride doped with boron, crystallizing with the same structure as titanium nitride TiN, and having a Vickers microhardness greater than approximately 50 GPa.
A part having a coating of titanium nitride doped with boron, the doped nitride crystallizing with the same structure as titanium nitride TiN, and having a Vickers microhardness greater than approximately 50 GPa.
A method for protecting a part from wear which comprises subjecting the part to a vacuum and depositing on such part in the vacuum titanium nitride doped with boron, the doped nitride crystallizing with the same structure as titanium nitride TiN, and having a Vickers microhardness greater than approximately 50 GPa.
