Friction Force Behavior in Dry Sliding of Inconel 600 Alloy Using Taguchi Method and Regression Analysis

The aim of the paper is to study friction force behavior by experimental investigation in the sliding of Inconel 600 alloy. The Inconel alloys are high-temperature Ni-Based alloy which have various applications like gas turbines, heat exchangers, condensers etc. The sliding tests are performed on a pin-on-disc tribometer. The Design of experiments technique is used to find out the number of experiments by using Taguchi’s L27 orthogonal array which is developed in MINTAB 14 software. The experiments were reduced for the various combinations to get the optimal parameters. The results showed that the friction force increases with the increase of load and speed. Also it is found that the speed was most significant parameter affecting frictional force. The regression model helps us to model the values for the responses.
