Abstract

Abstract

TC6 titanium alloy bars were annealed by four different heat treatment processes. The microstructure, wear resistance and corrosion resistance of the samples were tested and analyzed. The results show that under the heat treatment at 870 ℃ for 1.5 h, furnace cooling to 600 ℃ and insulation for 2 h followed by air cooling, the wear resistance and corrosion resistance of the alloy (sample 1^#) are the worst. The sample under the heat treatment at 900 ℃ for 1.5 h, furnace cooling to 600 ℃ and insulation for 2 h followed by air cooling shows the best wear resistance and corrosion resistance (sample 2^#). The corrosion potential and corrosion resistance of the samples respectively under the heat treatment processes of 920 ℃ for 1.5 h furnace cooling to 600 ℃ and insulation for 2 h air cooling(sample 3^#), and 900 ℃ for 1.5 h furnace cooling to 620 ℃ and insulation for 2 h air cooling (sample 4^#), are between those of the sample 1^# and sample 2^#. Compared with sample 1^#, the wear volume of sample 2^# decreases by 8×10⁻³ mm³, and the corrosion potential shifts by +53 mV.
