Corrosion characteristics of basalt short fiber reinforced with Al-7075 metal matrix composites

This paper reports a study of the corrosion characteristics of al 7075/ basalt short fiber metal matrix composites in 1 m hcl solution at room temperature as a function of percentage of reinforcement. the percentage of reinforcement was varied from 2.5 to 10 wt.% in steps of 2.5% and the composites were prepared by the liquid metallurgy technique. the weight loss method was used to determine the corrosion rate. the durations of the tests ranged from 24 to 96 hrs in the steps of 24 hrs. both the unreinforced matrix alloy and the composites were subjected to identical test conditions to study the influence of the reinforcement on al 7075/ basalt corrosion behavior. the corrosion rates of both the unreinforced matrix alloy and the composites decreased with the exposure time. the corrosion rate of mmcs was lower than that of matrix al 7075 alloy under the corrosive atmosphere. scanning electron microscopy (sem) was used to study the corroded surface of the specimens. © 2015 jordan journal of mechanical and industrial engineering.
