Abstract

The wear resistance and electrical resistance of the friction area of powder model composites based on Hadfield steel (Γ13 grade) and processed steel are determined under the conditions of sliding electrical contact at a current density of above 100 A/cm2. The structure of materials and the three-dimensional image of the friction surface are presented. The composite based on Γ13 steel is shown to form a contact area with high electrical resistance and roughness. It is found that the transition of the composite material on a steel counterbody occurs under the effect of electric erosion within the friction area. It is determined that the mode of catastrophic wear happens at a current density of ∼200 A/cm2.
