THE ZIRCOTEC PLASMA-SPRAY PROCESS
The Zircotec process is a derivative of the more general plasma-spray processing techniques outlined on an earlier page (see general outline). Zircotec's own in-house plasma-spray technology and our associated procedures were first developed within the UK nuclear industry when Zircotec formed part of the UK Atomic Energy Authority. These processes and procedures have been further developed and refined by Zircotec, resulting in the propriatory highly optimised plasma-spray process that we use today.
There are a large number of parameters that influence the interaction of the plasma-spray feedstock with the plasma jet and the substrate, and these parameters can result in very wide variations in the final product (eg. feedstock type and composition, feed-rate, plasma gas composition and flow rate, energy input, torch geometry, nozzle design, nozzle offset distance and substrate cooling). The Zircotec process ensures that these parameters are tightly controlled within pre-defined set points, thereby providing control over the quality of the final product. By controlling these parameters we are able to control material properties to suit specific applications.
