Superior Wear Resistance in EBM-Processed TC4 Alloy Compared with SLM and Forged Samples
The wear properties of Ti-6Al-4V alloy have drawn great attention in both aerospace and biomedical fields. The present study examines the wear properties of Ti-6Al-4V alloy as prepared by selective laser melting (SLM), electron beam melting (EBM) and conventional forging processes. The SLM and EBM samples show better wear resistance than the forged sample, which correlates to their higher hardness values and weak delamination tendencies. The EBM sample shows a lower wear rate than the SLM sample because of the formation of multiple horizontal cracks in the SLM sample, which results in heavier delamination. The results suggest that additive manufacturing processes offer significantly wear-resistant Ti-6Al-4V specimens in comparison to their counterparts produced by forging.

Effects of the Selective Laser Melting Process Parameters on the Functional Properties of the Co-Cr Alloy.
The purpose of the present study is to investigate the impact of technological parameters on the mechanical properties of the Co-Cr alloy after the Selective Laser Melting (SLM) process. The energy density (ε) and the number of the laser beam passes on each melted layer were the variables. The static tensile test was used to evaluate the mechanical properties of the manufactured samples. The results of the study show significant differences in material characteristics resulting from different number of the laser beam passes over the programmed path.

Technological problems in machining of resilient wheelsets on wheel-turning lathes with friction drive
Technological problems in machining of resilient wheelsets on wheel-turning lathes with friction drive: Article presents attempt of identification of technological problems in machining of resilient wheelsets on wheel- turning lathes with friction drive. Main part of presented research was modelling of machined wheel using finite elements method in conditions of load with forces measured during machining of railway wheelsets. Presented research is a part of works performed in order to enable regeneration of tyre profiles of resilient wheelsets using wheel-turning lathes with friction drive, which are commonly used nowadays for machining heavy railway wheelsets.
