Tribological properties are determined on a ring on-block arrangement, where the ring is made of aluminum alloy, A6063, and the block is made of the TiN duplex treated alloy tool steel, SKD61, and is compared with untreated, nitrided, and TiN ion-plated alloy tool steel. At higher loads and higher speeds, transfer of the aluminum alloy onto the tool steel occurs, which is little improved by the treatment. Wear of the tool steel takes place as the predominant mode of surface damage at lower loads and lower speeds, and is markedly reduced by the duplex treatment. Possible mechanisms of the improvement are discussed.
