A procedure for the study of wear of high strength (spheroid) cast iron under conditions of dry friction on surfaces with fixed abrasive following the kinematics scheme %26apos;pin-on-cylinder%26apos; with spiral movement has been developed. Five type specimens of high strength cast iron without and with micro-alloy of various Sn contents -0.08, 0.02, 0.06 and 0.12 mass.% were studied. The experimental results lead to graphs and diagrams of the relationships for the parameters mass and linear wear, wear rate and intensity, and wear resistance depending on process time, sliding way and normal load. %26lt;br%26gt;This study is connected with the completion of a PhD thesis and of the tasks under the Project %26apos;University R%26D Complex for Innovation and Transfer of Knowledge in Micro/Nano-technologies and Materials, Energy Efficiency and Virtual Engineering%26apos; funded by the Bulgarian Ministry of Education and Science.
