THERMAL NEUTRON-BLOCKING MATERIAL AND METHOD FOR PRODUCING SAME

摘要

[Problem] To provide a thermal neutron-blocking material having good corrosion resistance and stronger thermal neutron-blocking performance as a result of a B-containing cermet layer, which has good adhesion with a base metal, being formed on a metal surface. [Solution] A thermal neutron-blocking material in which a cermet layer is formed on a metal base material such as ordinary steel, steel alloy, tool steel, stainless steel, aluminum alloy, etc., wherein the cermet layer is formed from an MM'B or M2M'B2-type ternary boride and an M' metal phase (M, M' = transition metal). In addition, the cermet layer further comprises a binary boride. Furthermore, the cermet layer is a compound boride-type cermet formed from an M2M'B2-type compound boride and a binder phase of an M'-based alloy (M = Mo, M' = Ni or Fe).
