Al 2 O 3 /TiC ceramic composites with the additions of CaF 2 solid lubricants were produced by hot pressing. Sliding wear tests against cemented carbide were performed on these ceramic composites using the ring-block method. The friction coefficient and wear rates were measured. Results showed that the friction coefficient and the specific wear rate decreased with the increase...
The corrosion behaviour of a pitch-bonded magnesia-carbon refractory by an Al 2 O 3 rich (∼15wt.%) stainless steelmaking slag was investigated by rotating finger tests in a vacuum induction furnace at high temperature (>1650°C) and low oxygen partial pressure (1.5–4.3×10 −10 atm). This study confirms the poor slagline behaviour of MgO-C bricks industrially observed in VOD...
