This article explores the impact of friction stir processing (FSP) on the surface modification of magnesium alloy AZ91D. The purpose is to enhance the alloy’s surface qualities and, consequently, improve its performance in various applications. Using FSP, the microstructure and mechanical characteristics of the magnesium alloy are improved through solid-state joining. The study assesses the impact of FSP parameters on the alloy’s surface properties. Researchers adjust parameters such as tool rotation speed and traverse speed to achieve accurate FSP conditions for the intended surface alterations. The surface characteristics of FSP-treated magnesium alloy AZ91D are evaluated through detailed analyses, including microstructure, surface roughness, hardness, and wear resistance. The study considers the effect of FSP on grain development and microhardness, which reflect the immediate impact on surface properties. The study also examines how nano-sized boron nitride (BN) particles are distributed and dispersed during FSP. The addition of BN particles to the alloy through FSP is intended to further improve surface characteristics and wear resistance. The research concludes that FSP has the potential to modify the surface of magnesium alloys, resulting in surfaces with improved properties such as increased hardness, reduced surface roughness, and greater wear resistance. This study contributes to the development of high-performance magnesium-based materials, particularly in the automotive, aerospace, and electrical engineering sectors. FSP can expand the range of applications for magnesium alloy AZ91D and improve its overall performance.
