Development of Titanium Boride Grinding Wheel by Laser Sintering

Synthesis of Titanium Boride and Grinding Experiment

Abstract

This paper deals with development of a new method for producing profile grinding wheel. At first, the desired shape is made of metal that is machined easily. Next, powder material is spread on a surface of the metal. And the surface is scanned by a laser beam and then a ceramic layer is produced on the surface of the metal by the chemical reaction between the powder material and metal material. The produced ceramic layer is used as grinding wheel. The powder material is boron and the metal material is titanium in this experiment. The components of the layer are examined by X-ray diffraction and titanium boride is detected in the layer. Grinding experiment is performed using this grinding wheel. The results shows that the ceramic layer can be used to grind hardened die steel.
