Abstract

In this work, one of the main scientific and technological problem of laser cladding technology, increasing the powder usage coefficient are studied. Two-phase gas-powder flow are investigated. Physical and mathematical models of powder transportation process are discussed. The structure of gas-powder flows formed by the laser-cladding nozzle and the accuracy of focusing the jet of powder being researched. The main attention is focused on interaction between powder particles and nozzle wall. Presented data collected by gas-powder jet optic diagnostic, results of numerical simulation and their comparison.
