Abstract

The aim of the invention is to provide a method for the production of a protective layer on a martensitic steel. This is achieved by a method comprising the following steps: a) dipping the martensitic steel into a melt consisting of aluminium or an aluminium alloy under a protective gas atmosphere; b) withdrawing the steel from the melt and cooling it to a temperature which ranges from 100 DEG C to room temperature under said protective gas atmosphere; c) hot-isostatic pressing (HIP) of said steel under a pressure of at least 1,500 bar at the austenitisation temperature; d) quenching and tempering of said steel. Said steel which has been coated with said protective layer in this manner can be used as a structural material for nuclear fusion experiments in which said steel is brought into contact with tritium and/or a liquid metal.
