Japanese Patent JPH0819514
Kind Code:
B2
Abstract:
A method of forming a surface layer of carbide, nitride, carbonitride, or solid-solution on the surface of a material to be treated, which comprises disposing in a fluidized bed furnace a treating agent comprising a powder of a refractory material, and a powder of a metal for forming a carbide, nitride, carbonitride or solid-solution or a powder of an alloy thereof, introducing a fluidizing gas into the fluidized bed furnace to fluidize thetreating agent and form a fluidized layer, disposing the material to be treated in the fluidized layer, and introducing a predetermined amount of halide into the fluidized layer, and an apparatus for forming the surface layer on the material to be treated, comprising a furnace body for forming the surface layer in the fluidized layer of the treating agent, a heating furnace for heating the fluidized layer, a halide supply pipe in communicaition with the outside of the furnace body, and a halide gas jetting pipe disposed within the furnace body, which is connected to the halide supply pipe and has a plurality of apertures opened into the fluidized layer.
