The characteristics of the particle solid structure and the particle velocity distribution in the gas-powder (Fe-based alloy) stream for off-axis laser cladding were examined by particle image velocimetry technique, and the effect of feed parameters on them was also investigated. The results show that the solid and the gas in the stream were diverse of structure and velocity, and related to the property of materials and powder feed condition. The lower density is, the more concentrated of powder stream is. The particle velocity is lower than the gas velocity. At the transverse section, the particle velocity distribution can be described by Gaussian law. The particle velocity is enhanced with increasing rate of carrying gas flow, reducing powder feed rate and particle size.
