Abstract: A movable wall member, in form of an exhaust valve spindle (1) or a piston (7) for an internal combustion engine, comprises a base portion (17, 20) of an alloyed steel having a carbon-content in the range from 0.15 to 0.35% by weight, and an outer portion (14, 5) forming the surface of the wall member facing a combustion chamber. The outer portion is of a hot-corrosion-resistant alloy, which is nickel-based, chromium-based or cobalt-based. At least one buffer layer (18, 21) of an alloy is located in between the base portion and the outer portion. The alloy of the buffer layer is different from the alloyed steel of the base portion and different from the hot-corrosion-resistant alloy of the outer portion. The alloy of the buffer layer comprises from 0% to at the most 0.09% C in percent by weight of the buffer layer, and that the buffer layer has a thickness of at least 1.5 mm.

Abstract: A cylinder head is formed by positioning a clad preform including a first and second layer in a casting die cavity with the second layer in communication with the die cavity and the first layer facing outwardly to define a combustion surface. Molten material provided to the die cavity is solidified to form a cast portion metallurgically bonded to the second layer. An aperture of the preform forms a port in fluid communication with a passage of the cast portion. A plurality of dome-shaped preforms may define the combustion chambers of a cylinder head formed by the method. The preform may define a cylinder head face. The first layer may be a steel-based layer, and the second layer and cast portion may be aluminum-based, such that the first layer and combustion surface has higher thermal fatigue strength relative to the cast portion.

Abstract: A cast piston, for an internal combustion engine or pump has an integral coolant ring gallery, with localized extensions, to achieve a coolant interchange with the gallery upon piston reciprocation. At least a portion of an extension lies generally parallel to the longitudinal piston axis and towards an upper end of the piston adjacent the working fluid. This provides an attendant increase in surface area exposed to coolant allowing either a decrease in operational piston temperature or an increase in allowable heat flow into the piston from a working fluid.
