摘要： A method for applying a hardsurfacing material to a workpiece such as a reciprocating aircraft engine tappet in which a carbon-containing wear resistant material in powder form is applied to a surface of the workpiece in the molten state while a sharp temperature gradient is established from the surface into the body of the workpiece to ensure that solidification occurs from the body upward. The resulting surface material consists of wear resistant carbides in a tough martensitic matrix with minimal formation of graphite.

摘要： A cam follower having a two-piece composite laser welded configuration is disclosed and comprises a solid and alternatively thin wall tubular base (16) portion formed of mild steel and a thin-disc reaction portion (18) having a hardened, wear resistant outer surface portion (50). The reaction portion is joined to the base portion by laser welding which results in a weld zone (54) comprised of a fusion zone (56) bounded on either side thereof by heat affected zones (58) having relatively narrow transverse thicknesses. A method of laser welding the hardened reaction portion to the mild steel base portion is also disclosed.

摘要： A cam follower and process of manufacture in which a hardenable cast iron reaction member is welded, as by high energy beam welding, to the end of a tubular, mild steel base member. The surface of the reaction member may be decarburized before welding. The weld is preferably characterized by austenitic properties and is formed by an alloy of nickel with the metal of the cam follower members.

摘要： Wear resistant articles, especially valve seat inserts for internal combustion engines, are produced as sintered metal compacts comprising interspersed microzones of prealloyed austenitic stainless steel and softer ferrous metal, the microzones of austenitic stainless steel containing carbides and carbonitrides. The sintered compacts can be made by forming a green compact from prealloyed austenitic stainless steel powder atomizate blended with softer powdered ferrous metal component and powdered carbon, and sintering the green compact.

摘要： Thermal barriers (10, 26) fixed to mushroomed heads (12, 28) of poppet valves intended for diesel engines are disclosed. Thermal barrier (10) includes an insulating material (18) bonded to a face portion (12a) of mushroom head (12), a sheet metal shield (20) covering the insulating material, and a flange (22) clamped over the outer periphery of the shield and welded to the valve head. Thermal barrier (26) includes an insulating material encapsulated in a sheet metal sheath defining an evacuated chamber (32) which covers a face portion (28a) of the mushroom head (28), a sheet metal shield (30), and a flange portion (28b) integrally formed with the mushroom head and spun over the shield during final assembly to clamp the shield over the encapsulated insulating material. The flanges in both embodiments make line contact with the shield to minimize heat flow from the shields to the flanges and hence to the valve head.

摘要： An ultra light poppet valve for an internal combustion engine. The valve is formed by cold forming a blank into an elongated cup having an extremely thin wall and a flared open end onto which a cap is welded, the bottom end of the cup which defines the tip end of the valve having a wall section which is substantially of the thickness of the original blank. In accordance with one aspect of the invention, a keeper groove is formed adjacent the tip end as part of the cold forming process.
