Embodiment 3

[0059] The cubic boron nitride covered with a titanium film obtained by magnetron sputtering to cover a layer of titanium film in Example 1 was observed by an optical microscope. Specifically, in Example 1, the cubic boron nitride covered with a titanium film was obtained by magnetron sputtering to cover a layer of titanium film. The surface of the cubic boron nitride covered with titanium film has a bright metallic luster. The optical microscope picture obtained by using Ruixian Optical RX-500T digital microscope is as follows figure 1 shown, from figure 1 It can be seen that the surface of cubic boron nitride is coated with a layer of uniform titanium layer without exposed parts.
