Abstract

The hardness and specific wear rate of 3 dimensionally (3D) printed Ti6Al4V specimens were studied with respect to heat treatment temperature (HTT) in a range of 400-800 °C. Increasing the HTT from 400 °C to 500 °C promoted the hardness of the printed specimen while its decreased hardness associated with a further increase in the HTT to 800 °C was observed. Since higher wear resistance was the result of higher hardness, the trend of specific wear rate versus HTT of the printed specimen was opposite to that of its hardness versus HTT. The highest hardness and lowest wear of the printed specimen were therefore found at the HTT of 500 °C.

三维打印Ti6Al4V的硬度和耐磨性随热处理温度变化的研究

研究了在400-800°C范围内，三维（3D）打印的Ti6Al4V试样的硬度和比磨损率与热处理温度（HTT）的关系。将HTT从400°C增加到500°C提高了印刷样品的硬度，同时观察到其硬度降低与HTT进一步增加到800°C有关。由于较高的耐磨性是较高硬度的结果，因此印刷试样的比磨损率相对于HTT的趋势与其硬度相对于HTT相反。因此，在500°C的HTT下发现印刷样品的最高硬度和最低磨损。
