Embodiment Construction

[0020] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] An erosion-corrosion wear test bench, comprising a sample control mechanism and a liquid chamber 13 for holding experimental liquid, a part of the sample control mechanism can enter the liquid chamber 13, and a part of the sample control mechanism can also fix the sample 19 And arbitrarily change the spatial attitude of sample 19, such as figure 1 and figure 2 shown.

[0022] Through the sample control part, the inclination angles of the sample 19 corresponding to the three directions of X, Y, and Z in the spatial rectangular coordinate system can be adjusted arbitrarily, so as to achieve the purpose of adjusting the angle and direction of the impact of the water flow on the surface o...

Abstract

The invention provides an erosion-corrosion abrasion test table, which comprises a sample control mechanism and a liquid cavity (13) used for containing experiment liquid, wherein a part of the sample control mechanism can enter the liquid cavity (13); a part of the sample control mechanism can also fix a sample (19) and change the space posture of the sample (19). The erosion-corrosion abrasion test table can be used for performing multi-aspect regulation and control on the located environment of the sample; in addition, the space posture of the sample, the depth, the environment temperature, the liquid flow speed and the like can be precisely regulated and controlled on line.

Description

technical field [0001] The invention relates to an erosion-corrosion wear test bench suitable for carrying out erosion and corrosion wear experiments on target samples under different conditions. Background technique [0002] Abrasion caused by erosion and corrosion is the most important failure mode of workpieces (especially metal workpieces) working in fluid environment. For example, the turbine blades and ship propeller blades of hydroelectric generators will be impacted by the high-speed water flow, and the water may contain hard particles and active ions, which will cause various erosion and corrosion wear on the surface of the components, reducing the performance and life of the components. In order to study the erosion and corrosion wear mechanism and related influencing factors of various materials in different environments, corresponding test benches and equipment are essential. Due to the great difference in the working environment of different components, the cau...
