a Significant micro-morphological differences are observed with different sintering materials (with different ratios of SiC:W) and different sintering energy (Ed). With an increase in the content of W NPs, the porosity of the sintered body decreases, indicating that W serves as the laser absorber that facilitates sintering. b A unique “rock-embedded" dense morphology is formed in the case of SiC:W = 1:1, Ed = 45 J/mm2 and 60 J/mm2. The EDS image reveals that the spherical “rock" is enriched with element W. c The uniformity of the “rock-embedded" pattern should be induced by the mixing in the “melting pool" during the sintering.
