Embodiment Construction
[0022] 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 application will be further described in detail below in conjunction with the drawings and specific embodiments.
[0023] Such as figure 1 As shown, a bushing 4 of the present invention is made of a cylindrical body made of austenitic manganese steel as a base material, and a nano-modifier is uniformly dispersed and distributed in the base material. Wherein, the nanomaterial includes at least one of silicon nitride, titanium nitride, aluminum nitride, silicon carbide, titanium carbide, boron carbide, zirconium carbide, silicon boride, zirconium boride, and rare earth oxides. The content of the material accounts for 0.01%-0.30% of the total weight of the bushing; the content of the manganese alloy in the bushing 4 accounts for 6-18% of the total weight of the bushing 4 .
