Abstract: A corrosion resistant member to be exposed to a halogen-containing gas atmosphere or a halogen-containing gas plasma atmosphere, comprising a substrate and a plurality of layers deposited thereon including a layer of rare earth fluoride providing the outermost surface and a layer of rare earth oxide having a porosity of less than 5% underlying the rare earth fluoride layer.

Abstract: When a corrosion resistant member is exposed to a chlorine-containing gas or plasma thereof and then to the ambient atmosphere, the member surface does not absorb moisture. The surface of the member to be exposed to a chlorine-containing gas or a plasma thereof does not form chloride particles of substrate material. After washing of the member with water, the wash water exhibits no corrosive nature to the substrate. The member is free of damages to the substrate and of a loss of corrosion resistant capability.

Abstract: A Group IIIA element fluoride-containing coating comprising a Group IIIA element fluoride phase which contains at least 50% of a crystalline phase of the orthorhombic system belonging to space group Pnma is formed on a member for imparting corrosion resistance so that the member may be used in a corrosive halogen species-containing atmosphere. When the state of a crystalline phase is properly controlled, the coating experiences only a little color change by corrosion. A Group IIIA element fluoride-containing coating having a micro-Vickers hardness Hv of at least 100 is minimized in weight loss by-corrosion.

Abstract: Production of carbide shapes of silicon, titanium or vanadium by reaction of carbon with the metal in liquid phase such being carried out by heating a mixture of particles of carbon and particles of the metal rapidly to the melting point of the metal, thereby minimizing solid state reaction, and holding at a temperature and for a time sufficient to cause reaction. The metal and carbon particles are about 0.05 to 10 mm in diameter. An organic binder is used which volatilizes or dissociates upon heating.
