Abstract

A duplex surface treatment of tool steel, which comprises nitriding of a substrate and coating of a titanium nitride (TiN) layer, is studied as a potential tool material for plasticity processes of aluminum alloy without lubrication. Tribological properties are determined on a ring-on-block arrangement, where the ring is made of an aluminum alloy and the block is made of the TIN duplex treated tool steel, and is compared with untreated, nitrided, and TiN ion-plated tool steel. At higher loads and higher speeds, transfer of the aluminum alloy onto the tool steel occurs, which is little improved by th
