Analysis of Abrasive Wear Characteristics of Brass 60/40 Using MATLAB

Abrasive wear behavior of Brass 60/40 was investigated using pin on disc wear testing machine. The abrasive wear test of brass was conducted by taking two variables viz. orientation and normal load. The normal load varies from 5N to 35N with different orientation angles (0°, 30°, 45°, 60°, and 90°), the speed of rotating abrasive disc kept constant at 1500 rpm. The experimental data was obtained from 5N to 20N only, by using pin on disc wear testing machine, however the data beyond 20N were validated with help of MATLAB. For proper validation of result for wear (mass loss), the exploratory data analysis (EDA) and regression analysis (RA) are used. These two analyses were conducted on MATLAB by using curve fitting tool and surface fitting tool. After the completion of experimental work, the results showed reduction in wear (mass loss) under constant loading condition with increase in orientation angle while increased in wear (mass loss) under constant orientation angle with increase in normal load.
