- In this study, analysis on the oxidation behavior was conducted by a series of high-temperature oxidation tests at both 800°C, 900°C and 1000 in the air with sintered STS 316L. The weight gain of each oxidized specimen was measured, the oxidized surface morphologies and composition of oxidation layer were analyzed with Scanning Electron Microscope-Energy Dispersive x-ray Spectroscopy (SEM-EDS), finally, the phase change and composition of the oxidized specimen were shown by X-Ray Diffraction (XRD). As a result, the weight gain increased sharply at 1000°C when oxidation test was conducted for 210 hours. Also, a plentiful of pores were observed in the surface oxidation layers at 900°C for 210 hours. In addition, the following conclusions on oxidation behavior of sintered STS 316L can be obtained: Cr_2O_3 can be formed on pores by influxing oxygen through open-pores, (Fe_0.6Cr_0.4)_2O_3 can be generated on the inner oxidation layer, and Fe_2O_3 was on the outer oxidation layer. Also, NiFe_2O_4 could be precipitated if the oxidation time was kept longer.

- In this study, STS 316L powders with 3 wt.% Cu and 1 wt.% Sn known as corrosion-resistance reinforcement elements, are prepared to make different kinds of specimens, in which, 3 wt.% Cu and 1 wt.% Sn are added in different forms by mixing, alloying and fully alloying. After sintering in the same condition, the corrosion resistance, wear resistance and their mechanical properties of specimens are tested respectively. According to the comparison, STS 316L specimen sintered at 1270°C showed the most excellent mechanical property: HRB 78 (hardness), 1130.7 MPa (RCS), 26.6% (Fraction Wear), It was similar with the specimen made of STS316L and fully alloyed Cu and Sn powders, meanwhile, the latter one appears the best corrosion resistance, 75hrs-salt immersion test results. In addition, the specimens with Cu and Sn powders additive showed relatively worse wear resistance in compared with STS316L specimen.
