Corrosion-Resistance of Ni3Al Intermetallic Compounds Containing Cr Synthesized via Spark Plasma Sintering Process
Ni3Al intermetallic compounds containing Cr was synthesized via Spark Plasma Sintering process. These Ni3Al intermetallic compounds containing Cr have a nearly full density after sintered at 1100 °C for 5 min under the pressure of 40MPa. Microstructure and hardness of these intermetallic compounds was studied through metallograph observation and micro hardness tests. Their formation and strengthening mechanisms were analyzed and discussed in detail. The influence of the chromium content on corrosion resistance of these intermetallic compounds was analyzed by anode polarization curves. Results show that the corrosion resistance of Ni3Al intermetallic compounds is upgraded significantly with increasing chromium content.
