This paper describes a new technique for producing adherent solid lubricant films with full control of thickness and location. MoS2and FeCl2/CrCl3coatings are formed on Mo and Fe/Cr wires respectively by electrochemical deposition from a bath of molten LiCl/KCl, and their frictional behaviour is studied at 400 C. It is suggested that this method has applications in fundamental studies of solid-film and extreme-pressure lubrication, and also in warm wire-drawing and other metal-forming processes.Presented at the first ASLE International Conference on Solid Lubrication held in Denver, Colorado, August 24–27, 1971
