研究了高温高压水介质中某些金属的磨损特性.研究表明,当水介质压力为恒定时,磨损随着温度的增高而单调地增加;而当水温为一定时,介质压力具有显著减低磨损的作用.因此,在高温高压水介质中的金属磨损行为是这两种不同影响因素共同作用的结果.文中讨论了水的润滑作用,认为水的温度和压力是影响两滑动表面间介质膜性质的决定性因素.水介质压力可大为减轻磨损这一事实,对于压水堆中所使用的耐磨材料是一个有利因素.
The wear characteristics of some metals in high temperature and high pressure aqueous media are studied. The results show that the wear increases monotonically with the increase of temperature when the pressure of water medium is constant, while the media pressure has a significant reduction of wear when the water temperature is constant Therefore, the wear behavior of metal in high temperature and high pressure aqueous media is the result of the interaction of these two different factors.In this paper, the lubrication of water is discussed, and the temperature and pressure of water are considered to affect the properties of the dielectric film between the two sliding surfaces The decisive factor. The fact that water pressure can be greatly reduced can be a benefit for the wear resistant materials used in pressurized water reactors.
