Abstract :
[en] The wear characteristics of three high speed steel grades were studied, one of them being obtained from a conventional casting process and two others originated from a laser cladding route. Tribological tests were carried out at room temperature using a “pin-on-disc” device. The setting of the wear test parameters together with the microstructure of the studied materials seems to strongly influence the subsequent abrasion and wear mechanisms. The results show that the laser cladded high speed steel materials resist better to wear thanks to their ultrafine microstructure compared to the conventional cast material.
