Abstract

In mfg. components for the construction of machines and motors, where the components are made of spheroidal-graphite cast iron which is locally reinforced with another high-strength material consisting of an Fe-free or low-Fe alloy based on Co, or heat resistance alloys based on Ni-Cr-Si, the insert is electroplated with a layer of Sn, Cd or In on the surface(s) which come into contact with the nodular Fe, after which the insert is placed in a mould into which the nodular iron is cast. The electrolated coating on the insert is pref. 2-20 mu, esp. 2-10 mu thick. Used for casting inserts into nodular iron parts, e.g. displacement pistons for i.c. engines. The electroplated coating ensures a strong joint between the insert and the nodular iron.
