Abstract

The paper presents experimental research regarding the wear evolution of some steels obtained by GAS-CARBURIZING process function the composition of steel and compacting pressure. For the experimental work six mixtures of iron were used: Fe powder, Fe+0,2%Gr, Fe+1,5%Cu, Fe+3%Cu, Fe+1,5%Cu+0,2%Gr, Fe+3%Cu+0,2%Gr. The mixtures were pressed at three pressures 400, 500 respectively 600 MPa and the green compacts were gas carburizing for 90 minutes and sintered in the same cycle. To determine the wear behavior a CSM Instruments ball on disk tribometer was used..
