Received 18 July 2020 Revised 29 July 2020 Accepted 30 July 2020 Available online 31 August 2020 The effect of siliconizing on the corrosion behavior of heat-treated low carbon steel was analyzed. The steel was siliconized from 800C to 1000C with siliconizing time of 1 to 5hours. Hardness test was carried out to determine the optimized condition. The corrosion behavior was studied by varying HCl from 0.5 to 2.5M with time of 15 to 90days. The results obtained showed that optimized hardness values were obtained by siliconizing at 1000C for 3hours. Corrosion rate increased with increase in concentration of HCl from 0.5 to 2.0M. The siliconized sample showed lower corrosion rate when compared with the unsiliconized sample. The surface treatment (siliconizing) offer some corrosion protection to the mild steel. The wear rate was raised with increase in applied load and sliding speed.
