Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は多孔質の溶射皮膜を形成する方法に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a method of forming a porous thermal spray coating.
溶射皮膜の特性は溶射材料、粉末送給方式。 The characteristics of the thermal spray coating are the thermal spray material and the powder feeding method.

。Thermal spraying parameters such as spraying distance and heat source generation mechanism conditions are controlled to form a thermally sprayed coating according to the purpose.

ロールし皮膜形成している。Normally, to impart porosity to a thermally sprayed coating, coatings are formed by controlling thermal spraying parameters such as powder feeding method, spraying distance, and heat source generation conditions.
しかし、溶射パラメータのフントロールタケでは十分な
多孔性が得られないし、また多孔性のコントロールが困

問題点もある。However, there is a problem that sufficient porosity cannot be obtained with the thermal spraying parameters of Funtroltake, and that the porosity is difficult to control. Furthermore, since the thermal spraying parameter conditions that provide porosity are different from those for forming a normal thermal sprayed coating, there is also the problem that the yield of the thermally sprayed material is reduced.
本発明は多孔質の溶射皮膜の形成に際しての従来法の有

とを特徴とする多孔質皮膜の形成方法である。The present invention provides a method for forming a porous thermal sprayed coating of ceramic or metal, in which a thermal sprayed coating is formed by mixing ceramic powder or Kanejima powder, which is a material for forming the coating, with a resin, and the ceramic powder or metallic powder is mixed with a resin. This is a method for forming a porous coating, characterized in that the porosity of the sprayed coating is controlled by the mixing ratio with the above resin.

樹脂が溶射中に溶融・凝固を繰り返し体積変化を起すた
め、皮膜内部に貫通空孔が発生する。Because the melting point of the resin is low, the surface of the coating layered during the thermal spraying process is not in a molten or semi-molten state, and unmelted metal or ceramic particles, which conventionally did not contribute to coating formation, adhere to the coating surface and cause problems between the particles. Holes are generated in the pores. In addition, since the resin in the film undergoes repeated melting and solidification during thermal spraying and changes in volume, through-holes are generated inside the film.
