Wetting tests for Ni on (Ti_0.95Mo_0.05)(C_0.5N_0.5), (Ti_0.9Nb_0.1)(C_0.5N_0.5) and (Ti_0.85Nb_0.1Mo_0.05)(C_0.5N_0.5) ceramics were carried out at 1823 K and compared with those for the previous data. The larger the Mo content was, the smaller the contact angles were. The contact angle for (Ti_0.85Nb_0.1Mo_0.05)(C_0.5N_0.5) was smaller than for (Ti_0.95Mo_0.05)(C_0.5N_0.5). No new phase was observed on cross sections of the wet tested samples and microstructures could be divided into three regions: a Ni-rich region, reactive region, and substrate region. The depth of reactive region/height of Ni-rich region ratios for titanium carbonitrides containing Nb were larger than those for them containing Mo, and (Ti_0.85Nb_0.1Mo_0.05)(C_0.5N_0.5) had the largest ratio in all the samples.
