Abstract

The possibility of formation of porous materials for biomedical applications from VT6/Ta/Zr alloy by direct laser deposition has been shown. Varying the laser power allowed to obtain alloys with variable porosity. The modes providing formation of porous material with normal elasticity modulus corresponding to human bone were selected. It was found that the porosity value of 32% is achieved at the laser power of 50 W, which meets the requirements, for example, for dental prosthetics. In the process of direct laser deposition of materials in VT6/Ta/Zr alloys with variable porosity tantalum particles do not melt and act as crystallization centers. Such conditions ensure the formation of a highly dispersed metal structure consisting mainly of VT6 powders with evenly distributed Ta and Zr particles.
