[0039] By providing a multi-level layered wear-resistant component, the wear resistance of the bushing body can be effectively enhanced, the mechanical stability can be improved, and the requirements under harsh working conditions can be met by providing a multi-level layered sleeve body.

[0040] Working principle: The multi-layered wear-resistant assembly can withstand high impact and high temperature under extreme conditions, while ensuring surface wear resistance. The contact layer 114 has ultra-high hardness, resisting friction and wear, suitable for direct contact in high-wear environments. The high-temperature-resistant layer 115 is made of material that can withstand temperatures above 1000°C, preventing high-temperature damage. The impact-resistant layer 116 has excellent impact resistance and wear resistance. The mounting sub-port 110 inside the sleeve is a connecting groove, with locking threads inside to increase friction and stability after connection. The transition layer 112 is made of titanium metal-ceramic composite material, which can reduce stress concentration and enhance the bonding force between layers.

[0041] Example two:

[0042] Reference Figure 1 The difference between example two and example one is that the outer surface of the base ring 100 is fixedly installed with a buffer layer 117, the main material of which is titanium alloy, which improves the impact resistance and service life of the wear-resistant bushing in high-impact environments. The outer surface of the buffer layer 117 is fixedly installed with a self-lubricating layer 118, the main material of which is copper-based alloy embedded with molybdenum disulfide, which ensures that the bushing always maintains a low friction coefficient during operation, reduces maintenance requirements, and improves wear resistance.

The outer surface of the base ring 100 is fixedly installed with multiple reinforcing ribs 120, which are integrally cast with the base ring 100, improving the anti-deformation ability of the overall structure and enhancing the impact resistance and stability. The main material of the contact layer 114 is tungsten carbide, the high-temperature-resistant layer 115 is alumina ceramic, and the impact-resistant layer 116 is high-chromium alloy steel.

The multiple wear-resistant protrusions 119 installed on the outer surface of the wear-resistant layer 111 can increase wear resistance and reduce friction surface damage, and the boron carbide particles used have extremely high hardness, further enhancing their performance.
