摘要： A method and apparatus for forming a layer of a carbide or nitride of, for example, titanium or vanadium on the surface of material to be treated in a fluidized bed furnace. A refractory powder for forming a fluidized bed, a vessel or vessels filed with powder of a treating agent, and the material to be treated are placed in the furnace. The treating agent includes powder of at least one carbide or nitride forming metal or alloy and powder of at least one compound selected from the group consisting of chlorides, fluorides, bromides, iodides and boro-fluorides of alkali and alkaline earth metals and/or at least one of an ammonium halide and a metal halide. A fluidizing gas is introduced into the furnace under heat to form a fluidized bed in which the surface of the material to be treated is treated. The vessel or vessels are placed in the furnace in a spaced-apart relation from the material to be treated, so that no powder of the treating agent may adhere to the surface of the material to be treated.

摘要： A nitride or carbonitride layer is formed on the surface of a metal material as follows: A treating agent composed of a refractory powder of alumina or the like and a powder of a metal for forming a nitride or a carbide or an alloy thereof is disposed in a fluidized bed furnace; the treating agent is fluidized to form a fluidized bed by introducing an inert gas; the fluidized bed furnace is heated to a temperature of not higher than 700.degree. C.; an activator of a halogenated ammonium salt is intermittently supplied into the fluidized bed at a rate of 0.001 to 5 wt %/hour based on the total amount of the treating agent; and the metal material to be treated is disposed in the fluidized bed during or after any of the above steps. For example, a nitride layer composed of only a metal for forming a nitride which contains almost no Fe--N is formed on the surface of iron steel even at a temperature as low as not higher than 700.degree. C. The layer is very hard and efficient in wear resistance, and the toughness of the base metal is hardly lowered.

摘要： Particles of a layer-forming agent containing at least one element for forming a surface layer of e.g. a carbide on the material to be treated are disposed in a furnace below and/or at the side of the material to be treated. A fluidizing gas is introduced into the furnace below the layer-forming agent for fluidizing a powder of alumina or other refractory material to form a fluidized bed above the layer-forming agent, while the agent is not fluidized. The furnace is heated and a solid halide is supplied into the furnace below the layer-forming agent. The halide is sublimable to produce a gas which activates the element, so that it may combine with a particular element which the material to be treated contains, whereby the surface layer is formed thereon. An apparatus for forming such a surface layer is also provided.
