| Abstract | ||
| The aim of present work is to study the effect of different heat treatments [full annealing ,normalizing ,and hardening and tempering at (300C° ,600C°)] on general corrosion and erosion-corrosion for a carbon steel type (C35) in 3.5wt% NaCl solution as corrosive medium for general corrosion while in erosion-corrosion ,slurry with 1wt% SiO2 sand was added to 3.5wt% NaCl solution as the erodent. The experimental work tests were done using special device which was designed and manufactured according to (G73 ASTM) using traditional weight loss technique to measure weight loss rate or corrosion rate in (gmd) unit. It was found that the general corrosion rates for all heat treated specimens were lower than erosion-corrosion rate. The erosion-corrosion rate of specimen which was quenched and tempered at 600C° was found smaller than other heat treated specimens The normalizing heat treatment of low carbon steel improves the general pure corrosion resistance after immersion 20 day in 3.5 wt% NaCl solution. | ||
