Influence of the Roughness on the Mechanical Properties of Ti-6Al-4V Products Prepared by Direct Laser Deposition Technology

Abstract:

This article presents the technology of direct laser deposition. This technology is one of the most perspective new technologies. It allows realizing heterophase process during the manufacturing, in which the process of partial melting of the used powder is realized. The product is formed from a metal powder, which is supplied by a compressed gas-powder jet directly into the laser action zone. Ti-based alloys are interesting for many industrial areas, for example, engine systems, aircraft and shipbuilding, because of their corrosion resistance, low density and high strength. The influence of roughness on the mechanical properties of Ti-based products prepared by direct laser deposition was studied. It was found that the surface roughness distorts the values of the mechanical characteristics.
