Abstract
A metal or alloy of high melting point e.g. molybdenum, tungsten, tantalum, niobium, chromium, platinum, iridium, osmium or an alloy thereof, is first coated with an alloy containing at least 15 per cent of silicon and such layer is oxidized; a second layer of a material containing silicon is then applied and the whole heated to form a glaze. The silicon alloy may be as described, and may be applied and oxidized as described in the parent Specification; alloys of silicon with hafnium, calcium, tantalum, niobrium and cerium are however also referred to, as is application by electrolysis, by heating with silicon tetrachloride and hydrogen at 1200-1800 DEG C, as successive layers of aluminium and silicon heat treated to cause diffusion and by dipping into a molten alloy bath covered with common salt or carnellite. The second layer may also contain an oxide or oxides of titanium, aluminium, calcium, hafnium, thorium, beryllium, tantalum, niobium and cerium and may be applied as a powdered mixture, as a sintered powder or as a paste or suspension in an organic medium.
