METHOD FOR PRODUCING COATING FILM USING AEROSOL, FINE PARTICLES FOR USE THEREIN, AND COATING FILM AND COMPOSITE MATERIAL

摘要

A method for producing a coating film using an aerosol, which comprises admixing fine particles comprising a brittle material as a main component and having a 50 % average particle diameter (D50) based on the number of pieces of 100 to 300 nm with a carrier gas, to form an aerosol, and spraying the aerosol onto the surface of a substrate so as for the fine particles to collide against the substrate, to divide the 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.
