    • PURPOSE:To enable the repeated use of a metallic plate having blanked parts as a mask for spraying by coating the outside of the plate with polytetrafluoroethylene resin so as to prevent the deposition of a sprayed material. CONSTITUTION:The outside of a metallic plate 1 having parts 1a blanked to a prescribed pattern is coated with a layer of polytetrafluoroethylene resin to obtain a mask A for spraying. The mask A is used in the formation of thin films on prescribed parts by spraying fine powder of metal, ceramics or the like. The mask A has high flexibility, and since no sprayed material deposits on the mask A, the mask A can be repeatedly used with ease.

    • PURPOSE: To provide an alloy powder material for plasma spray showing sufficient corrosion resistance even with respect to a high temp. corrosive environment high in V-concn., containing Cr, Al and Y respectively in a predetermined ratio and comprising the remainder Ni.
      CONSTITUTION: A heat resistant Cr base alloy powder material for plasma spray contains, on the basis of a wt%, 50W70 Cr, 2W15 Al and 0.1W3.0 Y and balance Ni. In this case, for the sake of further improving the toughness and the close adhesiveness of a skin film at a high temp., 0.1W3.0% La or/and Ce can be contained in the aforementioned alloy. When this alloy powder is used as a plasma spray material to coat a substrate, for example, Hastelloy C by plasma spray, a strong plasma spray film especially excellent in V corrosion resistance at a high temp. is obtained.
