Problems solved by technology

[0003] Furthermore, for the existing jet injection device, the designer found that there are many defects, such as the separation of the sample pool and the reservoir, which takes up a large space, and the water level of the sample pool and the reservoir cannot be adjusted in association, resulting in waste of water resources; For example, the existing jet injection device is not convenient to observe the test phenomenon
In addition, the existing jet injection device still has problems such as single type of sample to be processed and lack of effective monitoring of the processing process.
[0004] In summary, looking at the research status of material surface treatment, the surface impact strengthening device based on high-pressure cavitation water jet is still in its infancy.

Embodiment Construction

[0025] Exemplary embodiments of the present invention are described in detail below. In addition, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a comprehensive understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in diagrammatic form to simplify the drawings.

[0026] In the present invention, the cavitation water jet impact strengthening is to spray the high-pressure water jet carrying huge energy onto the surface of the metal material in a specific way, so that the surface layer of the material undergoes plastic deformation at the recrystallization temperature and presents an ideal structure. Structure (that is, tissue strengthening) and residual stress distribution (that is, stress strengthening), so as to achieve the ...

Description

technical field [0001] The invention relates to the technical field of material surface treatment, in particular to a cavitation water jet impact strengthening device, especially a surface impact strengthening device based on high-pressure cavitation water jet. Background technique [0002] At present, the use of water jets is mainly concentrated in mining and petroleum fields, and high-pressure continuous water jets are used for cutting and cleaning. However, in terms of design and application research of water jet impact strengthening devices suitable for material surface modification, the background is relatively weak , no relevant reports have been seen. With the domestic emphasis on the research on the surface modification of materials, more attention should be paid to the water jet impact strengthening technology. Therefore, it is necessary to design and develop a series of related water jet impact strengthening devices. [0003] Furthermore, for the existing jet inje...
