Embodiment 1
[0057] 1) Put the sample to be tested into the erosion fixture, select the fixture to fix the sample, and set the erosion angles to 3 groups of 0°, 15°, 30°, 45°, 60°, 75°, and 90° respectively, Install each set of fixtures on 6 sets of fixtures, and connect the sample to the electrochemical measurement system with a test line;
[0058] 2) Prepare alkaline erosion solution components, pH = 10, use 50 mesh SiO 2 Granules, the solid mass fraction accounts for 10%, inject the erosion liquid components into the test chamber;
[0059] 3) Set the erosion rate of the rotating spindle to 800r / min, the test temperature to 25°C, and the test time to 20h, in which a group of samples is taken out every 20 hours for analysis and evaluation.
[0060] After the test, the wear conditions of the samples with different erosion angles and different erosion times were measured with a high-precision analytical balance, and the laser confocal profiler was used to quickly observe the erosion morpho...
