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 44):
The process of  claim 27 , wherein the workpiece is contacted with an additional gas different from said vapors to facilitate simultaneous nitriding or nitrocarburizing of the workpiece with activation, said additional gas containing at least one of a compound capable of decomposing to yield nitrogen atoms for nitriding, a compound capable of decomposing to yield carbon atoms for carburization, and a compound capable of decomposing to yield both nitrogen atoms and carbon atoms for nitrocarburizing.
