COATING METHOD AND COATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To smoothly form a flat millimeter-sized coating film even on a metal having high thermal conductivity without damaging the adhesive strength on the interface between the coating film and the metal. SOLUTION: The coating method for forming the coating film on the surface of the object to be worked by jetting metal powder at high speed comprises the steps of: forming a first coating film layer on a base material by jetting metal powder at the flying speed equal to or higher than the transition rate; and forming a second coating film layer on the surface of the first coating film layer by jetting metal powder at the flying speed lower than the transition rate.
