Theory and technology of sintering, heat, and chemical heat-treatment processes - Kinetics of interparticle contact formation during the laser sintering of two-component powders

The kinetics of interparticle contacts formation during the liquid-phase si ntering of unlike materials under the action of laser irradiation was inves tigated Trios of particles arranged in a row according to the schemes glass -polymer glass, metal-polymer-metal, and metal-glass-metal were sintered. T he processes of particle approach and liquid neck formation between particl es were studied. Possibilities for the manufacture of powder components wit h polymer and glass binders by the use of selective laser sintering followe d by heat treatment are considered.
