【摘要】：采用316L環(huán)塊和40Cr Mo圓盤試樣組成環(huán)塊-盤摩擦副進(jìn)行旋轉(zhuǎn)摩擦試驗(yàn),研究摩擦過程中40Cr Mo盤試樣的摩擦表面磁化現(xiàn)象,探討滑動速度、載荷對摩擦磁化的影響。結(jié)果表明,載荷較大時(shí),隨著滑動速度的增大,摩擦表面磁場逐漸增大;隨著載荷的增加,摩擦近表面溫度迅速上升,摩擦熱引發(fā)的消磁現(xiàn)象越發(fā)明顯,摩擦表面磁場增量出現(xiàn)先增后減的變化規(guī)律;載荷較大時(shí),摩擦近表面溫度會超過150℃后,導(dǎo)致摩擦表面的切向磁場增量減小,甚至出現(xiàn)負(fù)值。
[Abstract]:In this paper, the rotating friction test was carried out by using 316L ring block and 40Cr Mo disk specimen to study the phenomenon of friction surface magnetization of 40Cr Mo disk specimen during friction, and the effects of sliding speed and load on friction magnetization were discussed. The results show that the magnetic field of friction surface increases with the increase of sliding velocity when the load is large. With the increase of load, the temperature of near surface of friction rises rapidly, the phenomenon of degaussing induced by friction heat becomes more and more obvious, and the increment of magnetic field of friction surface increases first and then decreases. When the load is high, the near surface temperature of friction will exceed 150 鈩，
