| Popis: | The aim of this study is to explore the wear performance of AISI 316L stainless steel fabricated via selective laser melting along different directions with respect to the building direction and via post annealing. The wear behavior of the alloy under high-speed sliding was investigated with high sliding velocities of up to 1 m/s. It was shown that the wear behavior of the alloy was completely different from that in quasi-static wear environments. The high-speed wear resistance was significantly affected by the building direction. After the annealing heat treatment of the alloy at 800 °C for 4 h, the high-speed wear resistance significantly decreased. Therefore, special care must be taken in using SLM 316L alloys when subjected to wear environments with high sliding velocities. |
