Analysis of Scoring Resistance on Coated Spur Gears by Considering Surface Roughness

Abstract

G ears are often used as power and motion transmission elements in the automotive industry. The ability of the gears to operate comfortably at high power and speed depends on determining the factors causing the wear and obtaining the appropriate conditions. Scoring is a case of rapid separation of little particles which are adhered to each other by metallic contact from gear surface in gear systems that work simultaneously [1]. There are many ways to prevent scoring (profile correction, use of coating materials, lubrication, etc.). Coating materials are made for increasing the wear resistance of the material, preventing the discontinuity on metals (scratches, pores) and gaining functional quality [2]. The facing of gears by coating materials is a usual improvement of strength method Theoretical and experimental studies have been
