The influence of heat impact at 200 – 1050°C on the structure, phase composition, microhardness and tribological characteristics due to sliding over a NiCrBSi fixed abrasive (corundum) is studied for a PG-10N-01 coating deposited by a gas-powder laser method. A combined laser-and-heat treatment is suggested, which yields a heat-resistant chromium-n...

An alloy was fabricated with Ti-6Al-4V and Nb powder using laser deposition (LD) to form a compositional gradient. The gradient was deposited, starting with Ti-6Al-4V powder, onto a forged Ti-6Al-4V substrate in an Argon environment. Niobium (Nb) composition increased by 4-at.% with each layer deposited until the composition reached 100-at.% Nb. Th...

This paper has dealt with the formation mechanism of nanosized metal coatings on dielectrics; the coatings were produced using laser-induced deposition from liquid phase. A diode-pumped solid-state (DPSS) laser (532nm) was used in the deposition experiments. The laser power varied from 500 to 1500 mW with the single scanning rate up to 50μm/s. The ...

Selective laser melting (SLM) makes use of a high energy density laser beam to melt successive layers of metallic powders in order to create functional parts. The energy density of the laser is high enough to melt refractory metals like Ta and produce mechanically sound parts. Furthermore, the localized heat input causes a strong directional coolin...

The influence of surfactants on the result of laser induced copper deposition from solution on the dielectric surface was studied. The dependences of the topology of the copper structures on the hydrophilic—lipophilic balance of non-ionogenic surfactants was found. The surface tension at the gas phase—solution interface was measured. The best resul...

This study shows that AlSi10Mg parts with an extremely fine microstructure and a controllable texture can be obtained through Selective Laser Melting (SLM). Selective Laser Melting creates complex functional products by selectively melting powder particles of a powder bed layer after layer using a high energy laser beam. The high energy density app...

The composition of the gas phase formed during laser-induced chemical liquid phase deposition (LCLD) of copper was studied. Based on the results of a mass spectrometric study of the gases, 1H NMR spectra of the autocatalytic solutions, EDX spectra of the copper deposit, and the dielectric substrate, side reactions of organic components of the solut...
