Problems solved by technology

[0004] However, since there are many types of doping elements to choose from, and the parameters of the heat treatment process steps are also varied, so a better doping element of the TiN film is selected, and a suitable TiN film corresponding to it is found. The heat treatment method is of great significance and practical application value for improving the performance of TiN thin films and expanding the use range and conditions of cutting tools

Embodiment Construction

[0016] Hereinafter, the present invention will be described in detail through specific examples.

[0017] A cutting tool with a high-performance Ti-Mo-N multi-layer surface film is prepared by the following preparation steps:

[0018] It uses Ti, Mo, and N as the basic constituent elements of the film, and prepares a Ti-Mo-N ternary film on the surface of the cutting tool by magnetron sputtering;

[0019] Choose W6Mo5Cr4V2 high-speed steel as the base material of the cutting tool, first polish the surface of the base material, and clean it with hydrofluoric acid, acetone, alcohol, and deionized water in an ultrasonic cleaner for about 10 minutes, then dry it for later use;

[0020] Subsequently, the base material was placed on the sample stage in the vacuum chamber of the magnetron sputtering equipment, and the pure Ti target and Ti 50 Mo 50 Alloy targets are placed in different cathode target positions;

[0021] Then the vacuum degree in the vacuum chamber is evacuated to ...

Abstract

The invention provides a cutting tool with a Ti-Mo-N multi-element surface film. According to the invention, a Ti-Mo-N three-element film is prepared on the surface of the cutting tool by adopting a magnetic control sputtering method, and the cutting tool with the high-property Ti-Mo-N three-element film is obtained mainly by optimizing the preparation parameters of the multi-element film and the thermal treatment process parameters of the film. Compared with the Ti-N two-element film, a filmed cutting tool sample has smooth appearance and good compactness; by test, the elements on the surface of the film subjected to thermal treatment comprise the following components by atom percent: 30.5 of Ti, 28.3 of Mo and 41.2 of N; and the hardness of the surface of the film is 35 GPa, and the oxidization weight grain at the temperature of 800 DEG C is only half of that of the Ti-N film.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a cutting tool with a high-performance Ti-Mo-N multi-component surface film. Background technique [0002] Cutting tools have special substrates made of, for example, high-speed steel, hard metals, carbide metals, cermets, and the like. Single-layer or multi-layer thin-film coatings are often also applied to the substrate to improve the performance of the cutting tool. It is a conventional method to prepare Ti-N binary films with high hardness, wear resistance and excellent corrosion resistance on the surface of cutting tools. [0003] However, with the rapid development of modern industry, higher requirements are put forward for the performance of cutting tools, and it is urgent to improve its performance in terms of hardness, wear resistance, corrosion resistance, high temperature oxidation resistance, etc. Pure Ti- N binary films are becoming more and more inadequate in terms of hardness, w...
