摘要 The wettability between TiN ceramic substrates and steels with various Ti contents was studied under an argon atmosphere at 1550 °C using a modified sessile drop method. An electron probe microanalyzer and thermodynamic calculations were applied to investigate the interface between the steels and the TiN substrates as well as the surface of solidified steel droplets. The measured apparent contact angles between the TiN substrates and steels were 96°, 91°, and 146°, as the Ti content in the steel samples was 0.01, 0.31, and 0.68 wt.%, respectively. No reaction products were found at the interface, and only physical interactions occurred. The wettability between high titanium steels (0.68 wt.% Ti) and TiN ceramic substrates should be evaluated from various perspectives, as many TiN particles existing in steel made the apparent contact angle increased significantly, deviating from the true value of contact angle.
