도 7은 도 1에 있는 금속 코팅단계를 설명하는 순서도이다.7 is a flow chart illustrating the metal coating step in FIG.

도 7을 참조하면, 먼저, 치과보철물(A)의 표면을 플라즈마 처리한다(S110).Referring to FIG. 7, first, a surface of the dental prosthesis A is plasma treated (S110).

상술한 단계 S110에 있어서, 엔지니어링 플라스틱 수지로 이루어진 치과보철물(A)의 표면을 저압 플라즈마(Plasma)에 노출시켜 활성화시킴으로서 표면개질을 유도할 수 있다.In step S110 described above, surface modification may be induced by exposing and activating the surface of the dental prosthesis A made of an engineering plastic resin to a low pressure plasma.

스퍼터링이란, 물질에 이온 충격을 가하면 그 물질을 구성하는 원자나 분자가 튀어나와 주위의 물체면에 부착하는 현상을 의미하는 것으로, 불활성 기체의 이온화 작용은 비평형 방전 (Abnormal Glow Discharge)영역에서 이루어지며, 이온화된 기체는 전기장의 영향에 의해 음극표면을 가격하게 됨에 따라 스퍼터링법에서는 스퍼터링 타겟을 음극으로 사용하고 있으며 진공용기나 모재를 양극으로 사용하고 있다.Sputtering refers to the phenomenon that when an ion bombardment of a substance is applied, the atoms or molecules constituting the substance stick out and adhere to the surrounding object surface. The ionization action of an inert gas is performed in an absolute equilibrium discharge region. As the ionized gas strikes the surface of the cathode under the influence of the electric field, the sputtering method uses a sputtering target as the cathode and a vacuum vessel or a base material as the anode.

상술한 단계 S120에 있어서, 아르곤(Ar)가스를 주입하면서 스퍼터링 타겟을 음극으로 하고 음극 표면에 자기장을 걸어줌으로서 스퍼티링 타겟 표면위치에서 고리형(원형) 스퍼터링이 발생하여 원자분자가 활성화된 치과보철물(A)표면에 증착되어 금속을 코팅할 수 있다.In the above-described step S120, by injecting argon (Ar) gas, the sputtering target is used as a cathode and a magnetic field is applied to the surface of the cathode, whereby cyclic (circular) sputtering occurs at the surface of the sputtering target to activate atomic molecules. It may be deposited on the surface of the dental prosthesis (A) to coat the metal.
