Abstract

Abstract 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.

ATOMET 4601+TiC合金钢腐蚀特性的实验研究

本文主要研究了粉末冶金（P/M）新合成的（ATOMET 4601+2%TiC）高强度合金钢的腐蚀特性。长径比为0.5（h/d）的生坯在1100±10°C下在氮气吹扫的马弗电炉中烧结30分钟。烧结压块被冷锻以获得不同密度的合金钢预制件。采用酸洗介质对冷锻合金钢在不同时间段进行了电化学腐蚀和水浸腐蚀试验。实验结果表明，在ATOMET 4601中添加TiC降低了合金钢的腐蚀速率，并且发现腐蚀速率随着合金钢成分密度的增加而降低。表面形貌、SEM和XRD也证实了P/M合金钢的腐蚀特性。
