Abstract
There is provided a film forming method capable of enhancing adhesion efficiency of a metal powder by use of a low-pressure compressed gas even in the case of spraying the metal powder remaining in a solid-phase state to a substrate, to form a film, the method being a film forming method of spraying a metal powder p in a solid-phase state to a surface 11a of a substrate 11 along with a compressed gas, to form a film 12 of the metal powder p on the surface 11a of the substrate 11, wherein a powder, which at least contains a powder for film formation having an apparent density of 1.4 to 2.0 g/cm3 and an average grain size of not larger than 25 μm, is used as the metal powder p.
Claims12
A film forming method of spraying a metal powder in a solid-phase state to a surface of a substrate along with a compressed gas, to form a film from the metal powder on the surface of the substrate,
- characterized in that a powder, which at least contains a powder for film formation having an apparent density of 1.4 to 2.0 g/cm3 and an average grain size of not larger than 25 μm, is used as the metal powder;
- wherein the metal powder is made from at least one material selected from aluminum, nickel, copper, iron and alloys thereof.
