ABSTRACT
The chapter reports on the optimization of the tribological conditions of titanium grade 5 (Ti-Al-V-B4C) combinations using full factorial design. Powder metallurgy technique was used to prepare the titanium matrix composites. Using pin on disc machine, the elevated temperature wear behaviour was analyzed by varying the load (10–30 N) and temperature (30, 50, 100 and 150°C). By reinforcing the wt. % of nano B4C particles, the wear resistance was reduced irrespective of temperature and sliding distances. For the experimental test conditions, the factors (wt. % of B4C, sliding distance, load and pin temperature) were selected as self-determining variables. This design affects two responses: specific wear rate and coefficient of friction. Applied load, wt. % of the secondary particles and pin temperature play a significant role for wear properties.
