Abstract
An apparatus to coat cylinder bores with precise thickness and adhesion having a nozzle for effecting a hollow conical spray pattern of an emulsion about an axis, a highly pressurized supply of emulsion to the nozzle, the emulsion containing solid lubricant in fluid suspension and means for controllably moving the nozzle within the cylinder bore to deposit a coating of the emulsion in the thickness range of 8-13 microns. A method for coating cylinder bores includes preparing the cylinder bore surface to expose fresh metal free of contamination, generating a hollow conical spray consisting of fine mist droplets of a solid lubricant emulsion (the conical spray having an effective base with a diameter greater than the diameter of the cylinder bore), and moving the apex of the conical spray along the axis of the bore at a uniform speed to deposit a coating of the emulsion on the interior of such cylinder bore in a thickness no greater than 20 microns.
