| 摘要: |
| 摩擦磨损是造成材料失效的主要原因之一,减小摩擦磨损对工业发展与环境保护等方面有着重要意义。 而温度作为摩擦磨损试验的其中一个主要参数,对摩擦磨损过程具有重要影响。 该论文重点描述了温度对摩擦副摩擦学性能的影响,并分析了产生影响的机理和原因。 首先,温度会影响表面材料的理化性质,从而影响表面组织结构或者表面涂层;其次,摩擦副之中的固体或液体润滑剂性质随温度的变化发生改变并影响摩擦磨损性质,且在织构表面尤其明显。 最后,温度会对基底表面润湿性产生影响从而影响表面摩擦磨损性能。 该研究对在高温极限条件下工作的摩擦副的材料与润滑方式的选取,以及发动机、火箭等新型科技的发展具有重要意义。 |

| Abstract: |
| Friction and wear is one of the main failure modes of materials. Reducing friction and wear is significant for indus- trial development and environmental protection. The temperature is one of the major parameters in the friction and wear test, which has a great influence on the process of friction and wear. The influence of temperature on friction and wear performance is described and the mechanism and reason are analyzed. First of all, the temperature will affect the physical and chemical proper- ties of the surface materials, which could affect the surface structure and coating. Secondly, the properties of solid or liquid lu- bricants in the friction pair can be changed with the increase of temperature and the friction and wear properties could be observ- ably influenced, especially on the textured surface. At last, temperature will affect the surface friction and wear properties by changing the wettability of the base surface. The research is important to the selection of materials and lubrication modes of fric- tion pairs working under high temperature, as well as the development of new technologies such as engines and rockets. |
