    Abstract: 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.

    Abstract: A borided titanium article can include a titanium mass having titanium monoboride whiskers infiltrating inward from a surface of the titanium mass to form an integral surface hardened region. The titanium mass can be almost any titanium based metal or alloy such as high purity titanium, commercial grade titanium, α-titanium alloy, α+β titanium alloy, β-titanium alloy, titanium composite, and combinations thereof. Borided titanium articles can be formed by methods which include providing a titanium mass, contacting a surface of the titanium mass with a boron source medium, and heating the titanium mass and boron source medium to a temperature from about 700° C. to about 1600° C. The boron source medium can include a boron source and an activator selected to provide growth of titanium monoboride whiskers.
