ABSTRACT |
|
|
|
Weight loss corrosion studies of
ZA-27/red mud metal matrix composites are studied in this research
work. Metal matrix composites show improved corrosion resistance
than meals and alloys. They find their application in automobile and
air craft industries. ZA-27 is a commercially available alloy. Red
mud is a waste obtained after the removal of ZA-27 from its ore.
ZA-27 is reinforced with 2, 4, and 6 weight percentage of red mud
particulates by liquid melt metallurgy technique using vortex
method. Machined specimen was subjected to microstructural studies.
Weight loss corrosion tests were carried out according to ASTM
standards G-69 in sodium chloride and sodium hydroxide mediums.
Tests were conducted up to 96 h with 24 h interval. Corrosion rate
was found to be decreased with increase in exposure time in both
mediums. Effect of exposure time and presence of increased
percentage of reinforcement red mud is discussed in detail |
