Abstract
A process for producing a fluid transfer surface, which process comprises: providing a titanium or titanium alloy surface; subjecting the titanium or titanium alloy surface to surface hardening by interstitial element absorption to provide a hardened surface; and, if required engraving the hardened surface to provide a desired surface topography.

A process for producing a fluid transfer surface, which process comprises:
- providing a titanium or titanium alloy surface;
- subjecting the titanium or titanium alloy surface to surface hardening by interstitial element absorption to provide a hardened surface;
- and if required,
- engraving the hardened surface to provide a desired surface topography.
(canceled)
A method of repairing a fluid transfer surface, which comprises providing on the fluid transfer surface a layer of titanium or titanium alloy by cold spraying onto the surface titanium or titanium alloy particles and subjecting the titanium or titanium allow layer to surface hardening by interstitial element absorption to provide a hardened surface and, if required, engraving the hardened surface to provide a desired surface topography.
