Method for forming coating having composite coating particle size and coating formed thereby

Abstract

The present invention discloses the method for forming the coating having the composite coating particle size and the coating formed thereby, comprising the steps of: receiving, from a powder supply portion, a plurality of powders within a first powder particle size range, and transporting the powders using a transport gas; and forming a coating in which a plurality of first particles within a first coating particle size range and a plurality of second particles within a second coating particle size range, which is larger than the first coating particle size range, by causing the transported powders to collide with a substrate inside a process chamber at the speed of 100 to 500 m/s so as to be pulverized.
