Effect of cerium and neodymium addition in Ti Grade 2 on corrosion, wear and high-temperature oxidation resistance
Source abstract
Abstract
Rare-earth elements (REE)-added Ti alloys have competitive advantages owing to improved machinability, but the effects of REE on environmental durability have rarely been reported. In this study, we investigated effects of REE additions of 0.2, 0.8, and 2.0 wt.% cerium (Ce) and neodymium (Nd) in Ti on the microstructure, corrosion, high-temperature oxidation, and wear resistance. Microstructural analysis confirmed the formation of CeO 2 and Nd 2 O 3 precipitates, whose morphology and number density varied with the REE content. Such CeO 2 and Nd 2 O 3 precipitates affected corrosion resistance, high-temperature resistance, hardness and wear resistance. Due to the addition of REE in Ti, the oxidation state of Ti in surface oxide layer was changed, so that the corrosion resistance of Ti-Ce and Ti-Nd alloys were decreased with the increase of REE concentrations. Lower concentrations (0.2 and 0.8 wt.%) of REE addition in Ti contributed to precipitation hardening, thus the hardness and wear resistance increased compared to commercially pure titanium (CP-Ti), which is the base metal of REE-added Ti alloys. However, the coarsened CeO 2 and Nd 2 O 3 precipitates with 2.0 wt.% of Ce and Nd resulted in lower hardness and wear resistance than CP-Ti. Low concentration of REE (0.2 and 0.8 wt. %) enhanced a high-temperature oxidation resistance due to formation of compact initial oxide scale on surface. At the same REE concentration, Ti-Ce alloys showed better corrosion resistance, hardness, wear resistance and high-temperature oxidation resistance than Ti-Nd alloys.
