  Surface hardening of propeller material brings many advantages such as superior erosion resistance and increase of propeller efficiency. This study investigates the surface hardening characteristics and erosion resistance of AlBC3 treated by flame, induction and laser hardenings in view of the metallographic aspect. The microstructures and distributions of alloying elements of the test specimens were examined using a microscope and EPMA. Jominy test and ultrasonic erosion test were also conducted to evaluate the depth of surface hardening and the cavitation erosion resistance. The tests revealed that surface hardened by flame hardening is about 1.5 times harder than the as-cast and the hardness is closely related to the area ratio of the hard β + β’ phase to α phase on the microstructure. Laser hardening also produces harder surface, but the hardened layer is much thinner as compared to flame hardening thus contributing to the improvement of the erosion resistance of AlBC3 and is suitable for application to actual propellers.
