Additive manufacturing of high strength wear resistant materials -3D-printed metals gives new possibilities

摘要

The additive manufacturing industry (3D-printing) is growing quickly and are being more and more adapted to specific industrial needs. This presentation will present extremely wear resistant high strength materials made by additive manufacturing. The materials presented are Vibenite150, Vibenite280, and Vibenite350. The materials are PM-based with high carbide content and with a unique combination of wear resistance, strength and toughness. The top material Vibenite280 has a hardness of over 70 HRC and with the high carbide content, it has been proven to work very well in hobs for machining of gears and other wear applications. These materials have been developed from the idea that the major possibility with 3Dprinting is the combination of high wear resistance and complex geometries in near-netshape (NNS), so that it is possible to choose better materials in a tool or a component without need for soft machining. The presentation will show data of additive manufactured materials and a special highlight on gear cutting tools.
