John Institute of technology, Bangalore (INDIA) <p style="text-align: justify;">Metal matrix composites are heterogeneous systems containing matrix and reinforcement. Their physical and mechanical properties can be tailored according to requirement. They are used in automobile, aircraft and marine industries because of their increased corrosion resistance. In this paper weight loss corrosion tests are conducted on ZA-27/ TiO₂ metal matrix composites in different concentrated neutral chloride solutions like sodium chloride solutions. ZA-27 is the matrix and the reinforcement is TiO₂. Composites are prepared by liquid melt metallurgy technique using vortex method. Matrix alloy is also casted in the same way for comparison. Composites containing 2, 4 and 6 percent of TiO₂ are prepared according to ASTM standards. Cylindrical specimens of 20mm length, 20 mm dia are machined. Weight loss corrosion studies are carried out in 0.035%, 0.352% and 3.5% solutions of sodium chloride according to ASTM standards G69-80. Specimens are dipped in the corrodent and removed at every 24 hours of interval. Using the weight loss of the specimen the corrosion rate is calculated using the formula 534W/DAT. The corrosion rate decreases with increase in the exposure time for all specimens in all corrodents. Corrosion rate also decreases with the increase in reinforcement content of the composites.</p> <p dir="ltr">&nbsp;</p> <p dir="ltr" style="text-align: justify;">&nbsp;</p> https://journalofchemistry.org/paper/633/ ZA-27 TiO2 Vortex Corrodent Neutral chloride
