On Monday, Nov 18 at 11:00 a.m. in the CAES auditorium, KN Krishnan from the Charles Darwin Institution will present his work in materials related corrosion and friction stir welding research for advanced manufacturing. While the increase in demand for additive manufacturing, or 3D metal printing grows, one of the critical issues in the process is defects during fabrication. Krishnan will discuss how he’s working to improve the quality control process and defect detection methods.

Seminar Description
Materials underpin the performance of products and, more importantly, the manufacturing processes. Melting temperatures, deformation characteristics, crystal structure, oxide behaviour, density will influence the manufacturing processes that can be selected to fabricate parts. These properties have become important in additive manufacturing. Additive Manufacturing (AM), also known as 3D printing, is a rapidly evolving manufacturing process to produce complex and custom-made parts using layer-by-layer fabrication techniques. The increasing demand for high-quality parts has led to the need for developing methods to improve the quality control processes in AM. One of the critical issues in AM is the presence of defects. Defects can significantly affect the quality, mechanical properties, and functionality of the part, resulting in performance issues or product failure. Detecting defects in the initial stages of the manufacturing process is essential to prevent production of low-quality products and to minimise the risk of product failure. Research is underway to address a critical research gap by conducting a comprehensive investigation of the performance of different supervised learning algorithms for defect detection and quality prediction in AM. Some nuances of cold spray additive manufacturing will be discussed with respect to anti-microbial coatings and production of nickel aluminium bronze. Materials related corrosion work and Friction stir welding research at Charles Darwin University will also be presented.
