Zusammenfassung:PURPOSE: A blade on which a lubricity and wear resistance reinforced diamond like carbon coating layer is formed and a method for coating the blade are provided, and a LASIK operating blade on which a lubricity and wear resistance reinforced diamond like carbon coating layer is formed and a method for coating the blade are provided. CONSTITUTION: The method for diamond like carbon coating a blade comprises the steps of (a) cleaning the blade and installing the blade in a chamber; (b) plasma cleaning the blade under the vacuum degree of 1x10¬-4 torr or less for 1 to 10 minutes; and (c) carbon coating the plasma cleaned blade in the vacuum degree range of 5x10¬-4 to 100x10¬-5 torr for 10 to 200 minutes (S24), wherein the step (a) comprises (a1) cleaning the blade using alkaline cleaning solution and ultrasonic cleaner for 5 to 60 minutes, and cleaning the cleaned blade using alcohol and acetone (S21); (a2) mounting the blade on a jig; and (a3) mounting the blade mounted jig on the inner part of the chamber (S22), the vacuum degree is controlled by injecting nitrogen and/or argon gas into the chamber, temperature inside the chamber is maintained to 50 to 200 deg.C, electric current of an arc source used during the plasma cleaning and/or the carbon coating is maintained to 10 to 50 A, and the method further comprises (d) waiting until temperature inside the chamber reaches 50 deg.C or less after completing the carbon coating (S25); and (e) injecting nitrogen and/or air into the chamber so that pressure in the chamber is the same as the atmospheric pressure (S26). 본 발명은 다이아몬드성 카본층이 코팅된 수술용 칼날 및 그에 대한 코팅방법에 대한 것이다. 본 발명은 칼날을 코팅하는 방법에 있어서, 상기 칼날을 세정하고 챔버내에 설치하는 단계; 상기 칼날에 대하여 플라즈마 세정을 1 x 10torr 이하의 진공도에서 1분 내지 10분간 수행하는 단계; 및 상기 플라즈마 세정된 칼날에 대하여 5 x 10torr 내지 100 x 10torr 범위의 진공도에서 10분 내지 200분간 카본코팅을 수행하는 단계를 포함하는 칼날에 대한 다이아몬드성 카본 코팅 방법을 제공한다. 이로써, 라식수술용 칼날의 내마모성이 향상되어 하나의 칼날로 수술할 수 있는 회수를 증대시킴으로 인해 경제적 손실을 감소시키고 병원폐기물 처리에 따른 어려움을 해소하는 이점을 갖는다. 또한 칼날의 윤활성이 향상되어 절삭작업 수행시 각막과 같은 절삭대상의 표면이 종래의 칼날을 사용했을때에 비하여 매끄럽게 절삭되는 이점을 갖는다.
