“…Integration of laser cladding technology with computer-aided manufacturing and design (CAD/CAM), robotics, sensors, and control devices allows layer-by-layer manufacturing of components with complex geometry in a one-step process [5][6][7]. For example, thin-walled parts with a high aspect ratio for nuclear applications can be directly fabricated.…”

Проведено сравнение свойств материалов сталь СПН14А7М5 -карбид титана (0-30 об.% TiC), полученных лазерной наплавкой, лазерным спе-канием и способом порошковой металлургии (прессование и спекание). Исследованы процессы структурообразования, сопоставлена твер-дость разных образцов. Установлена возможность создания материалов с улучшенными характеристиками с помощью лазерных техноло-гий, в частности, поверхностного упрочнения изделий при использовании лазерной наплавки. Ключевые слова: лазер, наплавка, спекание, плавление, сталь, карбид титана, смесь, мощность, микроструктура, твердость, прочность.Comparison of the properties of materials: SPN14A7M5 steel -titanium carbide (0-30 vol.% TiC) produced by laser building-up, laser sintering, and powder metallurgy (compaction and sintering) has been carried out. Structure formation processes are investigated; the hardness of different samples is compared. The possibility of material production with improved characteristics by means of laser processing, in particular, of surface strengthening of products when using the laser building-up is established.

“…If laser power is high, sintering transforms into melting. When powders with different melting points are sintered, liquid-phase sintering proceeds, in which the fusible phase fills the pores of the refractory phase [16,17].…”

The layer-by-layer synthesis of 3D parts from nitinol (NiTi intermetallide) and hydroxyapatite additions using selective laser sintering/melting (SLS/SLM) is studied. The effect of different laser parameters on the structure and phase composition of sintered/melted samples is analyzed with optical and scanning electron microscopy, x-ray diffraction, and energy-dispersive x-ray analysis. Optimum SLS/SLM parameters are determined for the synthesis of NiTi + HA to be used in tissue engineering and manufacture of medical devices (pins, nails, porous implants, drug delivery systems). No significant destruction of HA ceramics under laser treatment is observed. The amount of nickel released to the surface of 3D parts decreases owing to the additional oxidation of free titanium during SLS/SLM and the formation of a protective HA layer. Full-density 3D parts are produced from nitinol by SLM including preheating to 300°C.
