Design, and fabrication of Pin on disc apparatus for investigation of tribological performance of base metal, Alloy, and Polymers against Mild Steel for sliding wear

As the test is been carried out for base metal copper, brass alloy and nylon, and Teflon from the polymer category. With this study, there is more change in volume, reduction in length, and weight of brass alloy for all the test parameter conditions at applied loads compared to other pin materials. Pitting arose when the load is increased. Although for polymers, Nylon has shown fewer deviations in length and weight compared to Teflon. Thus, showing that the material is a good alternative in the application again the material which has characteristics or BHN similar to Mild Steel. The wear volumes are thus appreciatively identified with the loading forces when speed is constant. Pin-on-disc wear apparatus is the crucial approach and underlying means for carrying the wear performance evaluations, additionally with details study the plasticity of material in the application can also be estimated. POD test results provide great benefactions for gauging innovation methodologies for increasing the life cycle of the component in service and achieving greater service efficiency and effectiveness of the materials as there is an increase in force on it. Hence, wear testing is the system for analyzing the friction or erosion due to rotation or action of rubbing of two surfaces which leads to the relegation of the materials from their primary form. Material which doesn’t work well in friction and wear phenomena is important for this mechanical test as the factual results can be witnessed. As there is an increase in weight the load also increases between the pin and disc; The pin and disc get pressed and thus the effects of load on adhesive wear were egregious due to this friction prevailing in such conditions giving rise to pits. The openness of a wear and tear testing machine and its practical results are the step towards effectual quality control and sound manufacturing practice with acceptable materials in application.
