RISTribological Properties of Hot-Pressed SrSO4 Ceramic at Elevated Temperatures in Dry Sliding Against Alumina Ball
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: SrSO4 ceramic was prepared by hot-pressed sintering and its friction behavior was investigated against the Al2O3 ball under the dry sliding condition from room temperature to 800 °C. From room temperature to 400 °C, the ...
Tribological Properties of Spark Plasma Sintered NiCr–Cr2AlC Composites at Elevated Temperature
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, layered ternary Cr2AlC powders with high purity and a size of 0.5–1 μm were synthesized by solid-state reaction method. NiCr–Cr2AlC composites have been prepared by spark plasma sintering (SPS) process. The ...
