METHOD FOR PRODUCING COATING FILM USING AEROSOL, PARTICLE MIXTURE THEREFOR, AND COATING FILM AND COMPOSITE MATERIAL

摘要

A method for producing a coating film using an aerosol, which comprises admixing a particle mixture comprising raw material fine particles containing a brittle material as a main component and having a 50 % average particle diameter on the volume basis of 0.010 to 1.0 mum and auxiliary particles containing, as a main component, a brittle material being of the same type as or a different type from the brittle material of the above raw material fine particles and having a 50 % average particle diameter on the volume basis of 3.0 to 100 mum, with a carrier gas, to form an aerosol, and spraying the aerosol onto the surface of a substrate so as for the particle mixture to collide against the substrate, to divide the raw material fine particles into finer ones or deform them by the collision and form the coating film on the substrate. The method allows the formation of a coating film having good quality with an extremely high rate of film forming.
