INFLUENCE OF CARBIDE STABILITY ON WEAR RESISTANCE OF ALLOY AT ELEVATED TEMPERATURE
高温环境中碳化物稳定性对合金抗磨性的影响

The influence of the stability of eutectic carbide in high Cr-Ni cast iron on abrasive wear resistance has been investigated on a high temperature abrasive wear tester, in which atmosphere can be controlled. The obtained results show that the carbide can not act as a resistant to wear if its chemical stability at elevated temperature is too bad, and the wear resistance of the alloy is decreased rapidly.
