摘要:
Part of the surface of a metallic-oxide refractory ceramic part, such as a fusion-cast refractory block, is treated using a high energy beam, to remove portions of the surface. A metal film may then be sprayed onto the treated surface of the ceramic part, for example to provide protection against erosion/corrosion in glass furnaces. Excellent adhesion between metal and ceramic can be attained.
摘要:
Metals for use in glass-making furnaces and which are susceptible to oxidation at furnace operating temperatures, especially iridium or molybdenum, are protected by applying at least (200) microns thickness of a coating formed of metal oxide particles in a metal oxide matrix. Oxidation, measured by weight loss, is significantly reduced.
