<p>A method of forming recesses (12) in an electrically conductive bearing surface, such as a surface of an air or fluid film bearing, comprises locating in spaced proximity to the bearing surface (19, 20) the surface of an electrode (15, 16) having a number of exposed conductors (30) in a configuration corresponding to the required configuration of the recesses, filling the space (23) between the surfaces with an electrolyte, and passing an electric current between the bearing surface and the electrode for a sufficient period to form recesses of the required depth in the bearing surface.</p> |
