Effect of nitridation and carburization of γ-TiAl alloys on wear resistance

The 1000-1300 K nitridation and carburization processes of MJ12 (Ti-47Al-2Nb-2Cr) and MJ47 (Ti-47Al-2Nb-2Mn+0.8TiB2) were studied in the purified ammonia and acetylene. Flow rate of the ammonia was kept constant at 10 cm3 s-1 and that of the acetylene was kept at 0.01, 0.03 and 0.05 cm3 s-1. The pro...
