Here are some methods to improve the wear resistance of bimetallic cylinder liners:
1. Optimize material selection:
Choose higher quality inner and outer sleeve materials, such as high chromium cast iron with higher hardness and better wear resistance as the inner sleeve material, and carbon steel with better strength and toughness as the outer sleeve material.
Research and use new wear-resistant alloy materials.
2. Improve manufacturing process:
Optimize the centrifugal casting process for the inner sleeve to ensure uniform material distribution, reduce internal defects, and improve the density of the structure.
Adopting heat treatment processes such as quenching and tempering to improve the microstructure of materials and enhance the balance between hardness and toughness.
3. Surface treatment technology:
Laser quenching, carburizing, nitriding and other treatments are carried out on the surface of the inner sleeve to increase surface hardness and wear resistance.
Using thermal spraying technology, such as spraying wear-resistant coatings (such as ceramic coatings), to improve the surface's wear resistance.
4. Optimize design:
Improve the structural design of cylinder liners, such as adjusting the fitting tolerance of the inner and outer sleeves reasonably to reduce stress concentration.
Optimize the shape and size of the cylinder liner, improve lubrication conditions, and reduce wear.
5. Strengthen quality control:
Strictly control the quality of each link in the production process, including raw material inspection, processing accuracy control, finished product testing, etc., to ensure the stability and consistency of product quality.
6. Lubrication improvement:
Choose the appropriate lubricant and ensure good lubrication during use, reducing friction coefficient and minimizing wear.
7. Regular maintenance and upkeep:
During use, regular inspections, cleaning, and maintenance should be carried out according to regulations, and severely worn cylinder liners should be replaced in a timely manner to avoid damage to other components due to excessive wear.
8. Simulation and experimental research:
Using computer simulation technology to analyze the stress and wear of cylinder liners during operation, providing a basis for improving design and manufacturing.
Conduct extensive experimental research to explore the effects of different factors on wear resistance and optimize relevant parameters.
