Corrosion and tribocorrosion behaviour of Ti-B4C composites processed by conventional sintering and hot-pressing technique

In this work, low volume reinforcement ex-situ Ti-B4C composites were produced using two different routes: conventional powder metallurgy (PM) and hot-pressing (HP). The effect of phases processing method on corrosion tribocorrosion behaviour studied. Composites processed by PM lost the typical passive Ti matrix, while HP presented similar to unreinforced Ti. Tribocorrosion tests showed that both composite groups times decrease in kinetics under sliding compared pure titanium. An antagonistic between wear was observed for with at least
