The significant increase of the compressive stress and the changes in the mechanical properties hardness and elastic modulus observed at 50% nitrogen concentration in the plasma may be

The behaviour observed in both samples under different conditions suggests that the wear mechanism during the test is the same, and to increase the wear and friction resistance of

In order to evaluate the effect of temperature and dynamic strain aging on the fatigue life, simple tensile tests were carried out on the material at 350C, which corresponds to the high

The tests have shown a reduction in the cutting force, and have highlighted the impact of laser assistance on the integrity surface roughness, appearance, residual stress and the tool
