Kinetics of interparticle contact formation during the laser sintering of two-component powders

摘要

The kinetics of interparticle contacts formationduring the liquid-phase sintering of unlike materials under theaction of laser irradiation was investigated. Trios of particlesarranged in a row according to the schemes glass-polymer glass,metal-polymer-metal, and metal-glass-metal were sintered. Theprocesses of particle approach and liquid neck formation betweenparticles were studied. Possibilities for the manufacture of powdercomponents with polymer and glass binders by the use of selectivelaser sintering followed by heat treatment are considered.
