Optimization and ballistic evaluation of SS410-Al2O3-SiC functional gradient armor material by laser cladding (PDF)

Scientific Study from the year 2023 in the subject Engineering - Metal Engineering, Metal Processing, Metal Structure, grade: A, University of Melbourne (Indian Institute of technology), course: PhD, language: English, abstract: The primary objective of this scientific study is to analyze the development and ballistic testing of a SS410-Al2O3-SiC-based functionally graded material (FGM) produced by laser cladding and hot pressing. The study focuses on optimizing the manufacturing parameters to maximize the quality of the composite cladding and compare its ballistic performance against traditional ceramic armor.

In this study, the fabrication of a functionally graded material (FGM) consisting of SS410, Al2O3 and SiC by laser cladding is investigated. The focus is on analyzing the influence of laser parameters on the microstructure and mechanical properties of the composite system, including hardness and elastic modulus, which are determined by scanning electron microscopy (SEM) and nanoindentation tests. Furthermore, the ballistic performance of the composite will be evaluated and compared to traditional ceramic armor. Future testing will include penetration and fracture toughness studies to confirm the material's suitability for ballistic protection applications.
