Embodiment 7
[0037] In Example 7, the matrix structure of the plow and shovel tip sample after quenching in a 300°C salt bath is martensite + upper bainite, and the impact toughness index is extremely low, which cannot meet the product use requirements;
[0038] Embodiments 4, 5, and 6 not only ensure the appearance quality of the plow and shovel tip sample, but also enable it to obtain higher strength and toughness.
[0039] The present invention has carried out a large number of tests to verify under different quenching and holding temperatures, times and quenching conditions, and the test results and rules are consistent with the above-mentioned embodiments.
[0040] Such as figure 1 As shown, the metallographic structure diagram of the iron-based wear-resistant layer sprayed and welded according to the test composition, it can be seen from the figure that the metallographic structure of the wear-resistant coating is composed of a martensite matrix and a uniformly distributed hard point...
