日本藤津首次在金属表面成功地进行了金刚石薄膜的涂覆。由于金属和金刚石的热膨胀系数不同(热振动可引起金属表面金刚石薄膜的剥落),所以,在过去,这种涂覆工艺是很困难的。藤津的技术是:在金属和金刚石薄膜之间形成一个中间层,以使从金属基体到金属表面的金刚石薄膜的热膨胀系数连续地变化,因此,不同的热膨胀系数不会引 Fujitsu Japan for the first time in the metal surface was successfully diamond film coating. This coating process has been difficult in the past due to the difference in coefficient of thermal expansion between metal and diamond, which can cause spalling of diamond films on metal surfaces. Fujitsu’s technique is to form an intermediate layer between the metal and the diamond film so that the thermal expansion coefficient of the diamond film from the metal substrate to the metal surface is continuously varied so that different coefficients of thermal expansion do not lead
