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...

Abstract

The invention discloses a method and a device for treating the surface of a cemented carbide tool with wide-beam N ions. The cemented carbide tool is placed on the target disk with the processing surface facing up, and a wide beam of N ions is injected to make a series of physical and chemical changes between the N ion and the surface of the cemented carbide tool substrate, improving the hardness and wear resistance of the material surface Etc., can improve the cutting characteristics of the tool, thereby increasing the service life of the carbide tool.

Description

Technical field: [0001] The invention relates to a method for treating the surface of a hard alloy tool, especially a method for treating the surface of a hard alloy tool with a wide-beam N ion implantation process to modify the surface. At the same time, it also relates to a method used in the method device. Background technique: [0002] At present, the method of material surface modification generally adopts surface coating method for cemented carbide cutting tools, that is, chemical vapor deposition coating method (CVD method) and physical vapor deposition coating method (PVD method). Although the above-mentioned surface coating method can change the surface characteristics of the cemented carbide cutter and improve its service life, there are two deficiencies in the above-mentioned method: on the one hand, the bonding force between the coating material and the surface of the cemented carbide cutter base material is not enough , easy to cause peeling; on the other hand,...
