The paper presents the effect of alloying with WC and TaC powders on structure and mechanical properties of the X40CrMoV5-1 steel surface layer using the HPDL (High Power Diode Laser). The metallographic investigations on light microscope show that during alloying the X40CrMoV5-1 hot work tool steel with the WC and TaC powder the obtained run face is characteristic of the high roughness, multiple pores, irregularity, and flashes at the borders. The changes of the surface layers hardness formed as a result of alloying with ceramic powders containing carbides are accompanied with the increased tribological properties. The microstructure of the alloyed layers which were formed on the surface of the investigated hot work steel was examined using optical microscope. The tribological wear relationships using pin-on-disc test were specified for surface layers subject to laser treatment, determining the friction coefficient, and mass loss of the investigated surfaces.

The concept for creating of high-strength coatings based on the structural theory of strength is proposed. It allows purposefully forming structure, that can effectively resist wear and fatigue. Surface laser alloying of steels with subsequent nitriding is studied. The increase in surface hardness, strength, wear resistance by 15 times and crack resistance by 1.5 times is shown in comparison with the standard parameters of steels.

AZ31 magnesium alloy preset SiC-316L powder by laser alloying on the surface treatment. The organizational structure and composition of alloying layer material by XRD, SEM and EDS phase were analyzed. The results show that the alloying layer surface has roughness, lap in good condition, no pilling, pores and cracks defect, etc. Alloying layer is mainly composed of the original phase Mg, Fe, SiC and the oxides of MgO and SiO2. The columnar grain zone perpendicular to the interface and pointing to the alloyed layer. It is formed in the bottom of the alloyed layer and the interface zone of magnesium alloy substrate.
