METHOD FOR OBTAINING A CERAMIC FILLER MATERIAL FOR THERMAL-SPRAYING TECHNIQUES

摘要

Method for obtaining a granular ceramic material suitable for use as filler material in the various techniques of thermal spray-coating. More specifically, the present invention relates to a method for obtaining a granular filler material of spherical shape, with a size within the range of 5 to 150 µm using suspensions of ceramic powders atomized in a cold medium and dried by means of a freeze-drying process.
