<p>The invention concerns a composite powder, consisting of spherical grains of homogeneous composition, each grain comprising at least two chemically reactive solids; and the method for preparing said powder by atomisation and drying. Said composite powder is particularly applicable in diffusion coating methods and it can in particular be used as carburizer in a pack carburizing process using halogenated precursors. Finally the invention concerns the resulting coatings.</p> |
