Estimating the term…
A developer sleeve for use in a monocomponent development system has a surface coating formed by an electric arc spray method. In one embodiment compressed air at a pressure of greater than 100 psi is used for driving the metal spray from the arc to the tube to be coated. In another embodiment, the developer sleeve is fabricated using mounting components of heat capacity and thermal conductivity both higher than that of the sleeve. In a still further embodiment, compressed air at a pressure of up to 100 psi is guided into the workpiece in order to dissipate heat from the interior of the workpiece. In a yet further embodiment, compressed air is used to aid disassembly of the sleeve from a mounting system following formation of the surface coating.
A method for fabricating a developer sleeve for use in a monocomponent development system comprising forming a surface coating by electric arc spraying, characterised by the use of compressed air at a pressure greater than 100 psi for driving the metal spray from the arc to the tube to be coated.
A method for fabricating a developer sleeve for use in a monocomponent development system, having a surface coating formed by an electric arc spray method, characterised by the use of compressed air for driving the metal spray from the arc to the tube to be coated, and by the use of mounting components of heat capacity and thermal conductivity both higher than that of the sleeve.
