The corrosion characteristics of newly synthesized (ATOMET 4601 + 2%TiC) high strength alloy steels through powder metallurgy (P/M) technique has been under taken in the present research work. The green compacts of 0.5 aspect ratio (h/d) were sintered at 1100 ± 10 °C for 30 min in nitrogen purged electric muffle furnace. The sintered compacts were cold forged to obtain various densities of alloy steels preforms. Electrochemical and aqueous immersion corrosion tests were carried out on the cold forged alloy steels using pickling acid medium at various time periods. The experimental results show that the addition of TiC to the ATOMET 4601 decreases the corrosion rate of alloy steel and the corrosion rate is found to decrease with increase in density in the alloy steel compositions. Surface morphology, SEM, and XRD were also corroborated with the corrosion characteristics of the P/M alloy steels.
The authors express their sincere gratitude to the Vice Chancellor, SASTRA Deemed To Be University, for granting permission to publish their research work. The authors are highly indebted to M/S Rio Tinto Metal Powders (formerly QMP), Europe, Middle East & Africa for providing ATOMET 4601 prealloyed powder.
