Spring travel limiter for protecting reinforcing creases in metal cylinder head gaskets from mechanical overload comprises laser coating of metal, alloy, plastic or ceramic applied directly to functional or stopper layer

摘要

The spring travel limiter (30) for protecting reinforcing creases in metal cylinder head gaskets comprises a laser coating of metal, alloy, plastic or ceramic applied directly to a functional (11) or stopper (20) layer. A structural bond (21) is produced between it and the layer, as in laser surface alloying.
