Embodiment 1

[0027] AIP-01 multi-arc ion coating machine is adopted, and a magnetic filter device is attached to the coating machine. Both the coating machine and the magnetic filtering device can be purchased from the market, and the magnetic filtering device is manufactured by the Institute of Low Energy Nuclear Physics of Beijing Normal University; the multi-arc The ion coating machine is manufactured by Shenyang Yuankehang Company; the workpiece used is the finished high-speed steel tool purchased from Zhuhai Tooling Factory, and then cut into 12×12×10mm squares by wire.

[0028] (1) First, the workpiece is mechanically ground and polished, and then pre-plated, that is, the workpiece is placed in a 10% NaOH solution and ultrasonically cleaned for 10 minutes; then ultrasonically cleaned with alcohol for 10 minutes, and then dehydrated and dried;

[0029] (2) Load the dried workpiece into the AIP-01 multi-arc ion coating machine, and place the polished side of the workpiece at 70 mm from ...

Embodiment 2

[0036] Device and workpiece are with embodiment 1.

[0037] (1) First, the workpiece is mechanically ground and polished, and then pre-plated, that is, the workpiece is placed in a 10% NaOH solution and ultrasonically cleaned for 10 minutes; then ultrasonically cleaned with alcohol for 10 minutes, and then dehydrated and dried;

[0038](2) Load the dried workpiece into the AIP-01 multi-arc ion coating machine, and place the polished side of the workpiece at 70 mm from the outlet of the magnetic filter elbow, allowing the plasma to bombard the surface of the sample;

[0039] (3) Set the temperature range of the heating tube in the vacuum chamber to 260°C to 280°C, and then use mechanical pumps, Roots pumps, and diffusion pumps to evacuate step by step. When the pressure in the vacuum chamber drops to 6.5×10 -3 When Pa or above, turn on the power cooling water and coating power supply, adjust the cleaning bias to -800V, the duty cycle is 40%, start the magnetic filter single arc...

Abstract

The invention discloses a magnetic filtration TiAlN/TiN thin film on the surface of tool and die material and a preparation method thereof. A layer of magnetic filtration TiN thin film is firstly plated on the surface of the tool and die material by adopting a magnetic filter, then a layer of magnetic filtration TiAlN thin film is plated, and the total thickness of double layers of thin films is 1 to 4 Mu m. The magnetic filtration TiAlN/TiN thin film has short preparation time, low cost and good wear resistance, is beneficial to prolonging the service life of the tool and die; and the processing quality of the plated film is high, the preparation technique is simple, the operation is easy and the plating process adopts electrical and mechanical automatic control.

Description

technical field [0001] The invention relates to the field of materials, in particular to a TiAlN / TiN thin film on the surface of a mold material and a preparation method thereof. Background technique [0002] In modern manufacturing, most parts are formed by tools and molds, which are made of matrix or steel materials. With the development of industrial technology, the working conditions of tools and molds are becoming increasingly harsh, and failure forms such as wear, cracking and plastic deformation often occur during use. Therefore, improving the service life of tools and dies can directly improve the productivity of the processing and manufacturing industry. [0003] TiN thin film material has high hardness and small friction coefficient. It is widely used in the surface protection layer of various parts because of its good wear resistance and corrosion resistance. Adding an appropriate amount of Al can further improve the mechanical properties of TiN, and to a certain...
