“…However, Co is known to be one of a main contributor to the occupational radiation exposure. Thus, for safety concerns, it is desirable to replace the Stellite 6 with Co-free hardfacing alloys having the equivalent properties [2].…”

“…Co-base Stellite alloys have traditionally been used as hardfacing materials for nuclear power plant valves due to their excellent wear and corrosion resistance [2]. However, it was found that the Stellite used in valve hardfacing, is one of the main sources of Co which is the major contributor of the radiation exposures in nuclear power plants [3].…”
