Abstract
An exemplary vane fronting surface for a variable geometry turbine includes a white layer that comprises nitrides. Such a layer may be formed using gas nitriding. As described, trials demonstrate that such nitriding reduces friction between a vane fronting surface and vanes of a variable geometry turbine. Consequently, nitriding can enhance longevity and controllability of a variable geometry turbine.
