摘要： A method or forming binderless clad powders using a high energy ball mill, preferably an attritor-type ball mill, is described. The binderless clad powders are formed by combining and processing a core material powder and a coating material (either a powder with significantly smaller particle size than the core material powder or a brittle material that will quickly form a powder with significantly smaller particle size than the core material powder) in a high energy ball mill for a relatively short time (generally less than one hour). The processing time employed is such that the particle size of the core material powder is not significantly reduced but that the clad powders are formed. At least one of the two materials (i.e., core forming material or coating forming material) must be deformable within the high energy ball mill. Such binderless clad powders are suitable for use as thermal spray powders and which can be thermally sprayed to form coatings on a various substrates.
