Abstract
In this paper, cold spray technology with a low pressure source was studied from a basic view point. Deposition tests of particle onto the substrate was conducted using a hand-made cold spray deposition device, and influence of nozzle shape, gas temperature, gas pressure, spraying period and substrate pre-heated temperature on the deposition rate were examined. As obtained results, it was found that a lot of particles could be deposited on the substrate under higher condition of gas temperature, gas pressure and the substrate temperature. In addition, a longer spraying period and shorter length of the nozzle led to high efficiency deposition in the cold spray process.
