✦ Synopsis

Cold Spray multicomponent coatings are deposited by a new powder injection method that consists of separate injection of each component of the powder mixture into a different zone of the carrier gas stream. Temperature and velocity of 10-40 Β΅m-sized aluminium and copper particles at the nozzle outlet are calculated. It is shown that these values depend considerably on the location of the point where the powder was injected into the gas stream. The method is experimentally validated by producing a composite aluminium-copper coating.

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 i

## Abstract Using electrostatic spray deposition (ESD), thin calcium phosphate layers were deposited onto commercially pure cp‐Ti substrates. ESD is a thin‐film technique that enables the deposition of inorganic thin films onto metallic substrates using a simple and cheap experimental set‐up. The r
