Abstract:Single point wear behaviors of PM Al Ti alloy have been in situ observed with environmental scanning electron microscope. Three micro wear modes, i.e. ploughing, wedge forming and cutting are observed with increase in the degree of penetration. The region for cutting mode is extended with increasing hardness of the alloy. In addition, the abrasive wear resistance of the Al Ti alloy does not decrease linearly with decrease in hardness.
Key words: Al Ti alloy wear mode in situ observation
