Tribological properties of ADI material

Abstract

After certain duration of contact, tribological properties of materials are relative and dependent both on the methods that determine them as well as on the conditions under which the contact between elements of the tribomechanical system is realised. In the paper are presented experimental results of tribological properties of 2 types of austempered ductile iron (ADI) pins in contact with carbon steel and grey iron discs. Study was performed on device with rotating disc and stationary pin and width, accompanied instruments for on-line measurements and data storing. During the study were obtained topology parameters of contact, friction coefficients of materials, width of wear trace and depth of the pin trace.
