摘      要：Laser additive manufacturing(LAM) of tungsten carbide metal matrix composites(MMCs) has been evaluated for surface modification of hot die forming tools,cutting edges,glass tooling,extrusion mandrels,and other abrasive wear *** work focuses on transitions from tool steels to MMCs through a single pass laser powder deposition *** related to the application of various metal powders and carbides used include surface hardness,porosity,cracking,and *** issues along with factory results that were obtained during this project are discussed.
