    摘要： A nozzle for a fuel valve (1) for an internal combustion engine, particularly a two-stroke crosshead engine, which nozzle for a fuel valve comprises a valve head (3) with a core portion (4) of an alloyed steel, and an outer facing (5) forming the surface of the nozzle towards a combustion chamber. The outer facing (5) has been formed from particulate starting material of a hot-corrosion-resistant alloy being nickel-based, chromium-based or cobalt based, where said particulate starting material has been united to a coherent layer. At least at the transition zone to the core portion (4) the particles in the particulate material of the outer facing (5) have been deformed into oval or elongate shapes by shear strain caused by forging the outer facing and the core portion, and that the forged outer facing (5) has a density of at least 98.0 %.

    摘要： The invention relates to a component (100) with at least two subcomponents made of metal. According to the invention, an alloy layer (140) is applied to the surface of a valve funnel (110) functioning as the subcomponent in a valve (100) functioning as the component, wherein the alloy layer (140) is made from a metal less noble than the valve funnel (110). The alloy layer (140) is arranged on a portion of the valve funnel (110) which is situated outside the direct mechanical action region (150) of the closing member (160) functioning as the second subcomponent, and is arranged as an annular portion running around the surface of the valve funnel (110), outside the mechanical action region of the closing member (160) relative to the closing member (160) resting in the valve seat (120) of the valve funnel in the closed state.
