New Tool of Ceramic Composites Based On Boride Armed By Directional Crystallization

Description

Borides off- and d- transition metals have high melting points, high harness, and a number of important functional properties. However, their intrinsic high brittleness hiders wide commercial application of these materials in modern technique.

Innovative Aspect and Main Advantages

A processing method for zirconium dodecaboride single crystals manufacturing has been developed. Cutting tools have been produced from the obtained single crystals and were successfully tested for cutting of titanium-based alloys. The developed cutting tools exhibited sufficient increase of the cutting effectiveness, as well as the improvement of the resulting surface quality as compared to the cutting tools from artificial diamond. Such results are possible due to the lower interaction between the cutting tool and the machined materials.

Areas of Application

Cutting tools for machining of titanium-based alloys, glasses, etc.

Stage of Development

A processing method for abrasive and lapping discs has been developed. A processing method for zirconium dodecaboride single crystals has been developed. It is planned to develop a method of reinforcement of such single crystals with the simultaneous improvement of the reproducibility of the processing method itself.
