Problems solved by technology

[0003] 1. The surface chemical plating, electroplating and other traditional processes, as well as the later development of brush plating, chemical plating, etc., although the combination of the coating and the substrate has been greatly improved, the wear under extrusion is still insufficient
In addition, the coating contains many harmful impurities, which are prone to oxidation and corrosion under high temperature conditions, resulting in the peeling and damage of the coating.
It is not easy to prepare ceramic coating
[0004] 2. The high-temperature wear-resistant material is welded to the surface of the substrate by surfacing welding. This method can form a thicker coating, but it cannot be surfacing welding ceramic coating
In recent years, the quality of the coating has been greatly improved by the use of low-pressure plasma spraying, but the coating under high-temperature extrusion condit

Embodiment Construction

[0022] According to the requirements of different workpieces, the preparation process of several technologies adopted in the method for preparing the high-temperature wear-resistant coating of the present invention can be carried out sequentially or alternately, and can also be repeated one or more times.

[0023] The present invention is described in detail below in conjunction with accompanying drawing:

[0024] The present invention is that high-temperature alloy steel workpiece [4] is installed in the vacuum chamber that has magnetron sputtering target [1], electron gun or laser device [2] and ion gun [3] to carry out the preparation of high-temperature wear-resistant coating (see figure 1 and figure 2 ). The production process is:

[0025] Put the substrate [A] on the surface of the workpiece into the vacuum chamber after routine cleaning, and wait until the vacuum degree in the vacuum chamber reaches 10 -3 After pa, ion beam surface sputtering cleaning is performed ...

Description

1. Technical field [0001] The invention belongs to a method for improving the high-temperature wear resistance of the surface of metal materials, and is mainly used for the preparation of alloy steel, such as high-temperature heat-strength steel, hot-working die steel, nickel-based alloy and cobalt-based alloy substrate surface coating. 2. Background technology [0002] Generally, the service temperature of high-temperature alloy steel is usually below 800°C. In order to use it at a higher temperature and in a harsher service environment, surface treatment must be carried out to improve the high-temperature resistance of the material. Existing coating preparation methods for improving the high-temperature wear resistance of the surface of metal materials include: [0003] 1. The surface chemical plating, electroplating and other traditional processes, as well as the later development of brush plating, chemical plating, etc., although the combination of the coating and the su...
