Oxidation Resistant Coatings for Molybdenum and Tungsten Parts
At H.C. Starck, we are continually improving our coating processes to provide molybdenum, tungsten and other refractory metals with outstanding protection against oxidation at high temperatures. Our molybdenum disilicide coatings are chemically bonded to the metal surface, so they do not separate or spall.H.C. Starck’s oxidation resistant coatings create a diamond-like finish on the product, so it can withstand knocks or scrapes during installation in furnaces.
H.C. Starck’s coating are widely used
for glass melting electrodes, atmosphere furnace fixtures, rollers, racks, die
plates and crucibles for quartz glass manufacture, and machined and fabricated
Mo and W parts that may be attacked by oxygen in the air.
Being produced via a chemical vapor deposition, the coatings can be applied uniformly to all surfaces including standard and threaded electrodes, and the inside of thin tubes. We are currently developing expanded uses for these coatings.
