| Abstract: | 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 µm-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. |
