“…The graphite morphology of the cast irons had a strong influence on the melting behavior. As already shown by the authors, [ 23 ] the beam guidance technique (multispot or meander technique) and the EB parameters used (acceleration voltage, beam current, focus position) determined the material‐specific results. The overall objective of the treatment was to achieve a remelting depth of approximately 1 mm and a crack‐ and pore‐free microstructure with the lowest possible surface deformation.…”

“…The surface deformations that occurred during this process, as well as the individual graphite particles that had floated up in the melt, were removed during subsequent surface grinding of the remelted surface. [ 23 ] After surface grinding, a mean remelting depth of t EBR = 0.92 ± 0.04 mm was measured for the 2.5Si–0.1Cu, and t EBR = 0.62 ± 0.04 mm for the 2.2Si–0.7Cu.…”

“…As descontinuidades em camadas podem ter origem nos nódulos de grafita dos ferros fundidos nodulares. Buchwalder e Zenker [63] produziram separadamente camadas de nitretos e boretos por nitretação e boretação, respectivamente. Na Figura 9(a-c) foram observadas descontinuidades nas camadas, decorrentes dos nódulos de grafita na superfície que, consequentemente, influenciaram a resistência ao desgaste da superfície.…”
