Abstract

The influence of high bonding coatings of TiAlN on textured titanium alloys to enhance tribological properties is investigated using a pin-on-disc tribometer at room temperature under the following range of loads [1] (80 N, 100 N, and 120 N), sliding velocities [2] (1.25 m/s, 2.1 m/s and 3.2 m/s) and sliding distances of (1125 m, 1890 m, and 2880 m). The predicted results are obtained using the design of experiments (DOE) technique response surface methodology (RSM) [3]. The results indicate that with an increase in the applied load and sliding velocities, the specific wear rate rises. On the other hand, as the sliding velocities of various sliding distances increase, the coefficient of friction drops. Microscopic images were taken to study the surface characterisation of actual and worn surfaces. The experimental results and the predicted results of RSM show close resemblance, and hence RSM is used for the prediction of wear characteristics.
