Embodiment 1
[0029] 1. First, degrease and derust the surface of the carbon steel, then use silicon carbide sandpaper to grind the surface of the carbon steel to 2000 grades, use a knife to carve a line along the vertical line of the long side of the sample, and then pass through high-purity water-ethanol - Rinse and wipe with high-purity water, dry with cold air, and place in a drying oven for later use;
[0030] 2 Configure 0.24mol / L ZnSO4 solution;
[0031] 3 Take a clean sample in a small crucible, add a few drops of 0.24mol / L ZnSO4 solution to the left half of the engraved vertical line, until about 90% of the left half is covered by ZnSO4 solution, and the thickness of the droplet film is about 2mm ;
[0032] 4 Place the above-mentioned treated carbon steel sample in the muffle furnace, control the heating rate at 15-20°C, raise the temperature to 230°C, keep it for 80 minutes, turn off the temperature control switch of the muffle furnace, and cool naturally;
[0033] 5 After the m...
