摘要
<jats:p>Al12Si was deposited by cold spray process. The influence of spray parameters on coating build up and coating microstructure was investigated. The process gas temperature was the crucial parameter for deposition of Al12Si. Increasing process gas temperature led on the one hand to a strong increase in the coating thickness, on the other hand to increasing coating porosity. In addition, the spray distance and the process gas flow rate could also have a significant influence, especially when spraying with higher process gas temperatures.</jats:p>
