摘要
本文用空气中的放电氧化处理,改善了 TiFe 合金的表面活性,使 TiFe 合金在常温下活化。空气中的放电氧化处理使 FeTi 合金表面形成了一系列不同性质的氧化物,产生了有利于氢化学吸咐的新的催化中心。
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.
