Abstract
A body containing at least 50% by weight of niobium is coated with particles of molybdenum disilicicle bonded together and to the body by material consisting of silicon or a mixture of silicon with one or more of chromium, boron and aluminium. Alternatively these metals may be added in powder form with the MoSi2. In an example the body coated with a slurry of MoSi2 and clay is immersed in a powdery mixture of equal quantities of alumina and silicon with 1 1/2 % by weight of ammonium chloride and the whole heated to 1350 DEG C. in argon. In another example the silicon may be deposited from a gaseous mixture of hydrogen and silicon tetrachloride. The coated body may be heated in a vacuum, and may be subsequently coated with a glass-like material. The niobium alloys disclosed are (per cent by weight) 10 T:, 10 W, remainder Nb, and 15 W, 5 Mo, 1 Zr, remainder Nb.
