| 英文摘要 | The wear behaviors of NiAl-28Cr-5.6Mo-0.25Ho-0.15Hf eutectic alloy against SiC ceramic under dry sliding from 600 to 1000 degrees C were investigated on a pin-on-disc test rig. The results show that the eutectic alloy exhibits excellent self-lubricating properties in the temperature range of 700-900 degrees C, which is attributed to the formation of 1-3 mu m thick glass-ceramic lubricant film. During wear testing the lubricant film was partially transferred to the SiC counterface, which avoided the direct tribo-contact between the alloy and SiC ceramic. At temperatures above 900 degrees C or below 700 degrees C the friction coefficient and wear rate are higher, owing to the adhesion between matrix and film weakening or no film forming. |
