Abstract
Cold spray is a new coating process. So the optimization of the gun nozzle and mechanisms of coating process aren't adequately revealed. This report examines the influence of the ratio of sectional areas at throat and exit of the gun nozzle and gas pressure on properties of cold sprayed copper coatings. And we got the result that there is a suitable ratio of the sectional area appropriate for nozzle intake gas pressure.
