With a total of 2 patents, Mathur's work has been instrumental in advancing materials used in demanding environments.

Latest Patents

Mathur's latest patents include the development of a Nickel-palladium-chromium-boron brazing alloy. This improved brazing alloy is particularly suited for use in high-temperature gas turbine engines. It features a composition range that exhibits X-ray inspection capability, enhanced stress rupture properties, good ductility, and oxidation resistance up to 1400°F. The alloy consists essentially of, by weight, about 20-80% Pd, 2-13% Cr, 1-4% B, with the balance being Ni and incidental impurities. It is capable of brazing in the 1800°F-2000°F temperature range and is less costly than gold-bearing brazing alloys currently in use.

Another significant patent is the Cobalt-palladium-silicon-boron brazing alloy. This alloy is also designed for high-temperature gas turbine engines and has a composition range that provides X-ray inspection capability, adequate stress rupture properties, ductility, and oxidation resistance. The composition consists essentially of about 25-95% Pd, up to about 5% Si, up to about 3.5% B, with the balance being Co and incidental impurities. This brazing alloy can operate in the 1800°F-2100°F temperature range and is more economical than existing gold-bearing brazing alloys.
