Fabrication of functionally graded TiC/Ti composites by Laser Engineered Net Shaping

Crack-free functionally graded TiC/Ti composite materials were fabricated by laser engineered net shaping (LENS), with compositions changing from pure Ti to approximately 95 vol% TiC. By delivering the constituent materials from different powder feeders and through process control, the LENS process can be used for the fabrication of functionally graded materials.
