<p>An embodiment of the present invention relates to a method for forming coating having a multi coating particle diameter and coating using same. According to the present invention, porosity is low, surface micro crack is absent, powder control is facilitated, laminating speed is high, semi-transparency is provided, and material characteristics are realized with ease. The present invention includes a step in which a powder supply unit supplies multiple powder having a first powder particle diameter and transport gas is used to transport the powder; and a step in which the transported powder is allowed to collide and be pulverized at a speed to 100 to 500 m/s in a base material in a process chamber so as to form coating in which multiple first particles having a first coating particle diameter and multiple second particles having a second coating particle diameter larger than the first coating particle diameter are mixed with each other. The first coating particle diameter of the first particle ranges from 1 nm to 900 nm and the second coating particle diameter of the second particle ranges from 900 nm to 10 mm.</p> |
