Microstructure and abrasive wear resistance of cast Ni …

The abrasive wear behaviour of directionally solidified Ni-Cr-C alloys was investigated using a pin-type test. M 7 C 3 carbide volume fractions (CVF) were varied from 0 to 40%. Two sets of alloys with different carbide and dendrite spacings were abraded with bonded SiC and corundum particles, varying the grit size and applied load.

Effect of Tin on the corrosion of Mg-5Al based alloy in …

The corrosion resistance of a Mg-5Al alloy was improved by the addition of tin up to 3.0 wt.% due to grain refinement, formation of a protective corrosion product layer, and the lower hydrogen evolution rate. On the other hand, the addition of 4.0 wt.% tin has a deleterious effect on the corrosion resistance of the Mg-5Al alloy in 3.5 wt.% NaCl solution as a result of the higher hydrogen
