Permeability Study of Austenitic Stainless Steel Surfaces Produced by Selective Laser Melting (open access)

Permeability Study of Austenitic Stainless Steel Surfaces Produced by Selective Laser Melting

In this article, permeability properties and surface roughness of stainless steel (SS316L) surfaces were evaluated through experimentation with three different laser scanning patterns (chessboard, meander, and stripe), and different sloping angles between the fabricated surface and the laser beam incident on the process. Results showed that for each scanning pattern, the roughness decreased as the sloping angle increased consistently in all experimental trials.

Effect of surfactants on pressure-sensitivity of carbon nanotube filled cement mortar composites (open access)

Effect of surfactants on pressure-sensitivity of carbon nanotube filled cement mortar composites

In this article, the pressure-sensitivity of CNT filled cement mortar composites with different concentrations of MWNT and different surfactants is investigated under repeated loading and impulsive loading, respectively. Experimental results indicate that the response of the electrical resistance of composites with NaDDBS to external force is more stable and sensitive than that of composites with SDS. Therefore, NaDDBS has higher efficiency than SDS for the dispersion of MWNT in cement mortar, and it is an effective surfactant for fabricating MWNT filled cement mortar composites with superior pressure-sensitivity.
