METHOD AND APPARATUS FOR FINE PARTICLE LIQUID SUSPENSION FEED FOR THERMAL SPRAY SYSTEM AND COATINGS FORMED THEREFROM

摘要

This invention relates to a method by which liquid feedstock suspensions containing fine particles, micron- and nano-sized, are injected, with sufficient droplet velocity, preferably axially, into a thermal spray apparatus for the production of high- quality nanostructured coatings. The method allows complete entrainment of the droplets in a high temperature gas stream, while the injection orifice remains potentially blockage-free for long periods of operation.
