摘要:
Disclosed herein is a method and gas atmosphere for a metal component in a continuous furnace. In one embodiment, the method and gas atmosphere comprises the use of an effective amount, or about 1 to about 10 percent volume of endo-gas, into an atmosphere comprising nitrogen and hydrogen. In another embodiment, there is provided a method sintering metal components in a furnace at a one or more operating temperatures comprising: providing a furnace comprising a belt comprising a wire mesh material wherein the metal components are supported thereupon; and sintering the components in the furnace in an atmosphere comprising nitrogen, hydrogen, and effective amount of endothermic gas at the one or more operating temperatures ranging from about 1800° F. to about 2200° F. wherein the amount of endothermic gas in the atmosphere is such that it is oxidizing to the wire mesh material and reducing to the metal components.
