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.
