摘要： A cylinder member for an internal combustion engine such as a valve, piston, cylinder liner or seat portion. The member has a welded high temperature corrosion resistant facing alloy with a hardness increased by use of a precipitation hardening mechanism based on a solid state phase transformation. The facing alloy has a temperature of activation of the precipitation hardening mechanism that is above the operating temperature of the alloy. The participation hardening mechanism acts so slowly that the alloy has not hardened at welding on the cylinder member Hardening occurs during a subsequent heat treatment at a temperature higher than the activation temperature for the participation hardening mechanism.

摘要： 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.
