Embodiment 3
[0032] 1. Mechanical performance test: The commonly used rotary cutting machine pressure roller material in the market is used as the control group, and three groups are respectively set up: 1 is the embodiment 1 group, 2 is the embodiment 2 group, and 3 is the control group; the specific test results are shown in the following table 1:
[0033] Table 1
[0034]
[0035] 2. According to GB10124-1988 metal material laboratory uniform corrosion full immersion test method, the sample prepared in the above example was placed obliquely in the 3.5% NaCl solution, and compared with the commonly used rotary cutting machine pressure roller material in the market, it was taken out after 4 days Use CrO3+AgNO3+Ba(NO3)2+distilled water to remove corrosion products on the surface of the sample, and then wash with acetone and absolute alcohol, and measure the corrosion rate (mm / a). The corrosion rates of the materials obtained in the above examples are shown in Table 2.
