It is very important to study the wear and friction properties of magnesium forgings in construction machinery for understanding their wear resistance and friction properties under actual working conditions. The following is an introduction to the research contents and methods in these two aspects:
- Wear study:
Wear is the amount of material lost from the surface of materials due to the action of forces during contact or friction with each other. Research on the wear performance of magnesium forgings of construction machinery usually includes the following:
- Wear mechanism analysis: Through the observation and analysis of the wear process, understand the wear mechanism of magnesium forgings in construction machinery under different working conditions, such as abrasive wear, fatigue wear, etc.
- Wear performance test: Use appropriate experimental devices and methods to simulate the friction and wear environment under real working conditions, and carry out wear performance tests, such as sliding wear test, wear resistance test, etc.
- Wear characterization and evaluation: By measuring the surface morphology and material structure changes of magnesium forgings of construction machinery after wear, use appropriate characterization methods to evaluate wear performance, such as wear volume loss, wear rate, etc.
- Frictional performance research:
Frictional property refers to the friction and friction coefficient generated by the material in the process of contact and relative motion. Research on the frictional properties of magnesium forgings of construction machinery can include the following aspects:
- Friction mechanism analysis: Explore the friction mechanism of magnesium forgings of construction machinery under different working conditions through theoretical models, such as dry friction, lubricating friction, etc.
- Friction characteristics test: Use friction testing machine or other experimental devices for friction performance test, measure the friction force, friction coefficient and other indicators between magnesium forgings of construction machinery and other materials, and study its relationship with working conditions, friction pair materials and other factors.
- Lubrication method research: According to the friction characteristics of magnesium forgings of construction machinery, suitable lubricants are studied to reduce the friction coefficient and extend the service life of magnesium forgings of construction machinery.
In the study of wear and friction properties, it is necessary to pay attention to the selection of experimental methods and comprehensive consideration of factors to obtain accurate and reliable results. At the same time, combined with the characteristics of the material, the working environment and the practical application needs, the surface treatment of the material, the lubrication method and the engineering design can be optimized, and the wear resistance and friction properties of the construction machinery magnesium forgings can be improved.
