Abstract:
A workpiece made from a self passivating metal and having one or more surface regions defining a Beilby layer as a result of a previous metal shaping operation is activated for subsequent low temperature gas hardening by exposing the workpiece to the vapors produced by heating an oxygen-free nitrogen halide salt.

Claim (Index 27):
A process for activating a workpiece for low temperature carburizing, nitrocarburizing or nitriding, the workpiece being made from a self passivating metal and having one or more surface regions which define a Beilby layer as a result of a previous metal shaping operation, the process comprising exposing the workpiece to contact with vapors produced by heating an oxygen-free nitrogen halide salt to a temperature which is high enough to convert the oxygen-free nitrogen halide salt to vapors, the workpiece being exposed to these vapors at an activating temperature which is below a temperature at which nitride and/or carbide precipitates form for a time sufficient to activate the workpiece, wherein nitriding the workpiece or nitrocarburizing the workpiece occurs simultaneously with activation of the workpiece.
