ACTIVATING TiFe ALLOY FOR HYDROGEN SORPTION BY SURFACE OXIDATION TREATMENT
用表面氧化处理改善 TiFe 合金的活化性能

It is difficult to activate TiFe alloy for hydrogen sorption.In this report amicro-electric-arc oxidation treatment was developed and it was found that TiFe alloycould be activated at the room temperature by such a surface oxidation treatment.It is be-lieved that the surface oxidation treatment broke the inert oxide film on the original surfaceand produced a series of new oxides with different compositions,structures and chemicalstates,which provide new catalytic centers for dissociatve hydrogen chemisorption.
