Abstract

510,404. Pistons. BERGHAUS, B. Oct. 24, 1938, Nos. 30737, 30738, 30739, 30740, (Convention dates, May 3), 30741 and 30742, (Convention dates, Aug. 20). Drawings to Specification. [Class 122 (i)] [Also in Groups XL and II] Light metal pistons for internal-combustion engines are coated, particularly at the head, by a metal layer or layers of a thickness of 0.005 to a few millimetres by thermal evaporation or cathode disintegration, The metal may be chromium, molybdenum, tungsten, iron, cobalt, nickel, copper, silver, platinum, palladium, rhodium, cadmium, zinc, tin, lead, aluminium, zirconium, magnesium, vanadium or tantalum singly or in any combination. The coating diffuses into or alloys with the main metal of the piston and a different metal may be applied to the head from that applied to the friction surface; the latter is preferably coated with copper, nickel, iron or chromium. The pressure within the chamber during deposition is between 3 to 10-6 m.m. or a neutral or reducing atmosphere of argon, nitrogen or hydrogen may be introduced at pressure below 50 mm. The piston is brought to a temperature of at least 200‹ C. during deposition by means of an electric discharge which may be adjusted by varying the pressure of the filling; the piston may also be heated before or after the deposition to assist diffusion of the metal. The piston may be of aluminium or magnesium or alloys of these metals. Two or more layers may be applied to the pistons, the layers may be of different metals chosen so that alloying with the main piston material is facilitated. Examples of magnesium and aluminium pistons of the Nelson Bohnalite type with suitable coatings are given.
