Wear Behavior Analysis On Cu-Al-Be Shape Memory Alloy Through Taguchi Approach

Abstract

The preparation of Cu-Al-Be SMA’s is the focus of this experimental work. The goal was to economically prepare them using
Gravity die casting and an induction furnace. The martensitic phase was obtained by subjecting the casts to a suitable thermal
procedure. The shape memory effect and hardness were evaluated using the Bend test and Vickers hardness equipment,
respectively. We Observed that an increase in the small addition of Be increases the hardness of the alloy. After confirmation of
SME, the wear test of Cu-Al-Be SMA's was performed using pin on disc equipment. The three discrete parameters, sliding
speed, applied load, and sliding distance, were analyzed using the Taguchi technique. The experiment plan is generated by
Taguchi's method, and based on the L27 orthogonal array, the experiments were conducted. ANOVA and regression models
were used to find the optimum wear characteristics for three discrete parameters: sliding distance, load, and speed. The
"smaller the best” is chosen, finally evaluated dry sliding wear resistance, and performed validation by experimental findings.
SEM is used to study the morphology of worn surfaces and their wear mechanisms. Microstructural studies showed that
adhesive, abrasive, brinelling, and surface fatigue wear mechanisms contribute to this SMA alloy wear.
