ABSTRACT:
A method for surface treatment in which a fluidizable powder mixture consisting of a powder of a refractory material, and a surface layer-forming powder of a metal, or alloy or both is fluidized by a fluidizing gas supplied through a gas distributor to form above the gas distributor a fluidized bed in which a surface layer is formed on the material to be treated under heating in the presence of a halide. A layer of coarse particles is disposed between the fluidized bed and the gas distributor, and the coarse particles have a mean diameter, D(m), as defined below:
