Investigation of Cooling Media on Wet Tribology Behavior of Mild Steel Treated at Various Temperatures

In the design of tools, gears, machines, and other engineering applications, it is important to understand the principles of tribology. This manuscript investigates the effect of cooling media (water, oil and air) and compare the wear rate and coefficient of friction of a mild steel treated at 500 and 900°C with the aim of selecting the best heating and cooling media. ASTM G99 test standard was followed for wet tribology. It was observed that parent sample exhibited lower wear rate of 4.999E-9 mm

/N/m and the higher wear rate was noticed under water cooling media heated at 500°C. During 900 °C heat treatment, the best media was found to be air during 10 N and oil during 20 N load.
