Wear and Hardness of Multidirectionally Forged Silicon Carbide Reinforced ZA27 Alloy Composite Materials

CODEN: MPCACD

Abstract

The goal of the current study is to determine how the wear and hardness parameters of 5 % silicon carbide reinforced ZA27 alloy composites are impacted by multidirectional forging (MDF). The composites were made using stir casting, a liquid metallurgy process. Under stresses of 1.10, the MDF process was applied to composite samples at 200°C, and 1,000 rpm was used as the counter disc rotation speed during the wear experiment, which was performed using pin-on-disc wear test equipment. In this investigation, wear test was conducted using sliding distances of 1,000, 1,500, and 2,000 m with weights of 30, 40, 50, and 60 N. The sample was examined using scanning electron microscopy (SEM) to study the worn surfaces. Investigation results demonstrated that MDF composites wore out far less frequently than non-MDF materials. At a load of 40 N and sliding speed of 1.25 m/s, the non-MDF sample showed a wear rate of 149 mg/m, whereas the MDF sample showed a wear rate of 138 mg/m. With an increase in applied load but a drop in speed, the wear rates of the matrix alloy and composites both increase. At low loads, the composite specimens showed abrasion wear, but at high loads, delamination wear was discovered to be more prevalent.
