Effect of Ageing on the Tribological Behavior of Inconel 690 Using Taguchi’s Method

Many of our modern technologies in the present day require materials with different combinations of properties that can be used for various applications. One such material is the Inconel 690 possessing various properties like high strength at elevated temperature, toughness, resistance to degradation in corrosive or oxidizing environment, etc. The present work is mainly focused on the study of Tribological properties of Inconel 690 at As Forged condition and at ageing conditions of 725°C for 4 hours respectively. The influences of process parameters like normal load, sliding distance and sliding velocity on the wear loss was studied using pin-on-disc apparatus. The experiments show that normal load is the most significant factor that influencing the wear loss. The work concluded that the combination of parameters that yields to minimum wear loss is not affected by ageing of the Inconel specimen to 725°C.
