Abstract:
1. A method of improving adhesiveness and compactness at an interface between a base material and a coating layer using a coating and ion beam mixing apparatus comprising an electron gun disposed in a reaction chamber in a vacuum, a coating material container located adjacent to the electron gun in the reaction chamber and irradiated with an electron beam generated from the electron gun, the base material being secured in an upper portion of the reaction chamber, one surface of which is coated with a coating material melted and vaporized in the coating material container, a jig mounted on another surface of the base material and configured to rotate the base material for uniform deposition of the coating material, and an ion beam irradiation device mounted on a side wall of the reaction chamber and configured to mix the coating material with the base material at the interface therebetween to improve adhesiveness and compactness of the coating layer, comprising: melting and vaporizing the coating material by radiating the electron beam into the coating material container (step 1); applying the coating material melted and vaporized in step 1 on the base material to form the coating layer, the coating layer having a thickness ranging from 20 to 200 nm (step 2); and radiating the coating layer with an ion beam at an energy value ranging from 50 to 500 keV to inject ionized atoms into the coating layer at an injection amount ranging from 1×10 wherein the coating material is SiC and the base material is Ni—Cr alloys, and wherein after the surface of the base material is completely coated in step 2, the coated base material is rotated by tilting the jig to face an ion beam irradiation inlet in order to expose the coating layer on the base material to the ion beam radiated from the ion beam irradiation device.
