Analysis of corrosion on sintered stainless steel: Mechanical and physical aspects

The experimental results demonstrate that both the weight and density increase when Ev is increased. The corrosion tests exhibited slightly different corrosion behaviors as a function of the Ev used. Samples deposited at the maximum energy generally exhibited less corrosion and the highest tensile properties owing to the low distribution of defects inside the sample. However, improved tensile properties continued to emerge following each exposure time interval in the corrosion process. It was found that the influence of the “exposure time interval” factor is non-existent for the ultimate tensile strength, yield stress, and strain at fracture, as these did not change with the accelerated corrosion exposure time.
