PRECIPITATION HARDENING OF TANTALUM COATED METALS |
摘要 |
A process includes: (a) providing a tantalum-coated metal alloy substrate; (b) heat annealing the tantalum-coated metal alloy substrate by heating to an annealing temperature for the tantalum-coated metal alloy substrate, holding at the annealing temperature for a period of time and then quenching to a temperature below 50 degrees Celsius; (c) heating the tantalum-coated metal substrate to the precipitation hardening temperature of the metal alloy substrate; and (d) cooling the tantalum-coated metal alloy substrate to a temperature below 50 degrees Celsius; wherein the process is further characterized by carrying out steps (b)-(d) under a tantalum-inert gas atmosphere and by quenching in step (b) and cooling in step (d) being carried out by flowing a tantalum-inert gas having a temperature of less than 50 degrees Celsius over the tantalum-coated metal alloy substrate. |
