Latest Patents
Hilboldt's latest patents include a Nickel-palladium-chromium-boron brazing alloy and a Cobalt-palladium-silicon-boron brazing alloy. The Nickel-palladium-chromium-boron brazing alloy is designed for high-temperature gas turbine engines, featuring a composition that allows for X-ray inspection capability, improved stress rupture properties, good ductility, and oxidation resistance up to 1400°F. This alloy consists of approximately 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 more cost-effective than gold-bearing brazing alloys currently in use.
The Cobalt-palladium-silicon-boron brazing alloy is also tailored for high-temperature gas turbine engines. Its composition allows for adequate stress rupture properties, ductility, and oxidation resistance. This alloy consists of about 25-95% Pd, up to 5% Si, up to 3.5% B, with the balance being Co and incidental impurities. It can braze in the 1800°F-2100°F temperature range and is less expensive than existing gold-bearing brazing alloys.
