The present study includes heat treatment investigations of tool steel surfaces for the optimization of the tribological properties by generating selective oxide layers. Therefore, an experimental heating setup – combining inductive and convective heating – has been developed as a hybrid heating process under protective gas atmosphere. Selective oxidation is realized by controlling the residual oxygen content. Thus, specimens are going to be heated near-surface above tempering temperature avoiding the loss of mechanical properties. Different oxide layer systems are going to be evaluated by analyzing tribological stresses after selective oxidation. Therefore diffusing effects between base material, oxide layer and process atmosphere have to be investigated. The tribological durability is represented by friction characteristics and analysis of tribological wear of the oxide layer.
Within the study these new heat treatment processes and the determination of wear characteristics of oxide layers generated at higher surface temperatures will be presented.
