A crankcase for a reciprocating piston engine, in particular of a motor vehicle, includes at least first one wall region that has a greater wall thickness than at least one second wall region of the crankcase that adjoins the first wall region. The crankcase is produced from an aluminum alloy and by at least mainly laminar die casting and is heat-treated completely or heat-treated completely and additionally locally or heat-treated only locally.

Crankcase for a reciprocating piston engine, in particular of a motor vehicle

A method for coating a substrate, in which a wire-shaped spray material is melted in an electric arc and is deposited as a functional layer on the substrate. The invention also relates to a functional layer which can be produced on the substrate by this method. The functional layer has a high hardness value and good corrosion resistance on exposure to diesel fuel with a high sulphur proportion.

Method for coating a substrate with a spray material and functional layer achievable with this method

A wire-like spray material () based on an iron for electric arc wire spraying and also a functional layer () which can be produced therewith on a substrate (). The functional layer () has good corrosion resistance towards diesel fuel having a high sulphur content.
