摘要 |
<p>An apparatus and method are described for simultaneously thermal spraying at least two types of powders onto a substrate (10), wherein both powder types are carried by a single spray stream (15) and impacted upon the substrate (10). According to the invention, the different powder types are injected into the spray stream (15) through separate powder ports (22,24) in such a manner that there is substantially no mixing of the powder types in the spray stream. The spray system (12) and substrate (10) being sprayed are moved relative to each other to produce a homogeneous sprayed powder deposit.</p> |
