65 1
Abstract:
A refractory metal substrate suitable for use in contact with molten glass is coated with a chromium oxide outer coating and a molybdenum disilicide buffer coating to protect the substrate from oxidation at elevated temperatures, particularly during start up of an electric furnace.
Refractory Metal Substrate And Coatings Therefor
US Patent:
4812372, Mar 14, 1989
Filed:
Jan 25, 1988
Appl. No.:
7/147963
Inventors:
Subhash S. Kithany - Reynoldsburg OH
Assignee:
Owens-Corning Fiberglas Corporation - Toledo OH
International Classification:
B32B 1501, C03B 542
US Classification:
428664
Abstract:
A refractory metal substrate suitable for use in contact with an oxygen- or nitrogen-containing environment at a temperature greater than the oxidation or mitridation acceleration temperature of the substrate is disclosed. The refractory metal substrate comprises a refractory metal comprised of molybdenum and having a coating comprised of chromium metal. In an alternative embodiment the refractory metal can be an alloy comprised of in weight percent: from about 10 to about 20 chromium, from about 0 to about 5 alumina (Al. sub. 2 O. sub. 3), from about 0 to about 1 yttria (Y. sub. 2 O. sub. 3), from about 0 to about 0. 5 titanium, from about 0 to about 0. 1 zirconium, the balance being essentially molybdenum to make 100% of the composition; and, optionally having a coating of chromium metal.
