Abstract Scope |
High temperature oxidation of 316L austenitic stainless steel manufactured by the selective laser melting (SLM) was investigated. Oxidation tests of 316L and 316L made by SLM were conducted in a horizontal heating tube in experimental air at 600 ℃ up to 500 h. Multi characterization techniques including X-ray diffraction, scanning electric microscope, Raman spectra, and energy dispersive spectrometer were used to confirm the compositions and distribution of corrosion products. Results show that oxidation kinetics of investigated materials followed a sub-parabolic oxidation law. The weight gain of 316L made by SLM was slightly higher than that of 316L. Original surfaces of 316L and 316L made by SLM were attributed to the higher weight gains. Surface grinding of investigated materials was beneficial for their corrosion resistance by developing an intact Cr-rich oxide scale. |
