Microstructure, Hardness, and Wear Behavior Investigation of the Surface Nanocomposite Metal Matrix Reinforced by Silicon Carbide And Alumina Nanoparticles.

behaviour of Al/8wt.% TiB2 composite fabricated by liquid metallurgy technique. A statistical approach, known as the Taguchi method, was implemented to identify optimum wear parameters. The wear test has been conducted in a pin-on-disc (EN32 steel) wear testing machine. Analysis of variance (ANOVA) technique is applied to check the validity of the developed model. Wear loss and co-efficient of friction were measured in an applied load range of 30 - 50 N, sliding velocity range of 0.5- 2.5 m/s and sliding distance of 1200 - 1500 m. Micro structures of worn surfaces were characterized by scanning electron microscope (SEM).

1.INTRODUCTION The optimization of wear process parameters is a critical aspect in enhancing the performance of aluminum-based insitu formed Titanium Diboride (TiB2) Metal Matrix Composites (MMCs). These composites, known for their lightweight and high-strength characteristics, hold significant promise for applications in industries such as aerospace and automotive. This research endeavors to systematically investigate and optimize the wear process parameters, including factors such as applied load, sliding speed, and the concentration of TiB2 reinforcement, with the goal of improving the wear resistance of the composite. By delving into the intricate interplay of these parameters, this study aims to provide valuable insights into maximizing the durability and tribological properties of aluminum-based insitu formed TiB2 MMCs, thereby contributing to the advancement of materials engineering for cutting-edge industrial applications.

3. Problem Statement  In-situ formed composites represent an alternative way to overcome the current limitations of ex-situ composites and monolithic materials. The main issue faced during the ex-situ composites in the Al-MMCs is low mechanical, tribological properties.  In-situ formed (TiB2) is known to be an excellent material for the strength and better ability to transfer the load. Moreover, refine the grain boundaries results in better mechanical and tribological properties as compared with exsitu composites.
