Embodiment Construction
[0016] The invention uses an ion implanter to treat the surface of a cemented carbide tool with wide-beam N ions. The ion implanter has been improved on the basis of the original ion implanter. It adopts a wide-beam nitrogen ion source (beam spot diameter 120-150mm), removes the mass selection and ion beam scanning system, and sets four flanges on the vacuum chamber. And the movable workpiece target platform, and a rotating system is added under the vacuum chamber, so that the workpiece target platform and the target disc on the workpiece target platform can rotate with the rotation of the rotating system.
[0017] see Figure 1-Figure 3 As shown, the above-mentioned ion implanter includes a vacuum chamber 1, a workpiece target stage 2 provided with a target disk 21, and the workpiece target stage 2 is located on a horizontal plane above the centerline 11 of the vacuum chamber, preferably on a horizontal plane 35 mm away from the centerline; The vacuum chamber 1 is provided w...
