TRIBOLOGICAL CONSIDERATIONS ON RWL 34 TOOLS STEEL

Abstract

The paper presents an analyze of the tribological testing on the RWL 34 tools steels in diffrent stages: untreated, hardened and hardened and tempered. The wear tests were made by ball on disk, which is an oscilating sliding method. Two types of materials were used for the counterbody balls, namely: steel (100Cr6) and alumina (Al2O3). The coefficients of friction, worn track sections, worn cap diameters and samples wear rates at diffrent loads (4 and 6 N) were measured. A comparation between all three stages of the material and parameters of the wear tests was made.
