| description | The structural and phase states of surface layers of the titanium VT1-0, VT3-1, VT-6 and VT-8 alloys after laser treatment in various gas environments, VT25-U alloy after twist extrusion and subsequent laser treatment, and VT1-0 alloy after laser alloying with powders of pure elements Fe, Co, Ni are investigated. As shown, the mentioned types of treatments lead to an increase in the surface-layers’ microhardness values. The influence of the surrounding gas atmosphere and the titanium-alloy chemical composition on the structure-formation processes during their laser melting and on the microhardness value of the treated layers is analysed. The effect of laser treatment of the surface of sintered single-phase powder titanium VT1-0-type alloys on the porosity level in the melting zone is investigated. As established, the microhardness in the laser-melting zone of the VT25U alloy exceeds the samples’ microhardness after heat treatments and twist extrusion. Therefore, the presented laser surface-treatment modes act as an effective method of titanium-alloy surface treatment, since they have a qualitative effect on structure that, in turn, leads to an improvement in the mechanical characteristics of the surface layers. |
