ABSTRACT:
An apparatus and method are described for simultaneously thermal spraying at least two types of powders onto a substrate, wherein both powder types are carried by a single spray stream and impacted upon the substrate. According to the invention, the different powder types are injected into the spray stream through separate powder ports in such a manner that there is substantially no mixing of the powder types in the spray stream. The spray system and substrate being sprayed are moved relative to each other to produce a homogeneous sprayed powder deposit.
