CHEMMAT 754 : Materials Performance Enhancement

Engineering

2021 Semester Two (1215) (15 POINTS)

Course Prescription

Materials under extreme service conditions – surface engineering, high-temperature corrosion/oxidation. Nanomaterials and nanotechnology – special properties, synthesis and processing techniques, applications in sensing, catalysis and biomedical areas. Advanced manufacturing technology – additive manufacturing, powder metallurgy, and sustainable/green manufacturing. Selected advanced concepts in materials performance enhancement are taught through research based individual projects.

Course Overview

This is a NZQF Level 9 elective paper after CHEMMAT 121, 204 and 305. Materials are the base of modern technology and decide the functions, working efficiency, and cost of a machine/devoce.  However, materials often need to work under extreme service conditions including high temperature and severe wear, especially in chemical process engineering and energy related industries.  Understanding of materials failure mechanisms under these conditions and protection of materials with surface technologies are important for engineers working in a wide range of manufacturing industries.  This paper also covers new development of materials including Nanomaterials and Nanotechnology, and Advanced Manufacturing Technologies such as Additive and Sustainable/Green Manufacturing.

(Capability 1.1, 2.1, 2.2, 3.1, 3.2, 4.1 and 5.2)
  3. Demonstrate an understanding of on Tribology, Friction and Wear of Materials. Student will understand the generic features inherent to a “surface” and how these are quantified, as well as how these contribute to the definition of a “tribological system”. Students should understand the generic concept of “friction” and be able to interpret/apply the three laws of frication in a practical context. From this understanding the student should be familiar with the different mechanisms of lubrication and where these apply in a wear system. Finally, the student should know the generic mechanisms of sliding, adhesive and erosive wear, the key variables that influence the extent of wear in each regime, and how the wear rates for these mechanism are quantified. (Capability 1.1, 2.1, 2.2, 3.2, 4.2 and 5.2)
  4. Demonstrate an understanding of Nanomaterials and Nanotechnology: Student will be introduced to the history and development of nanomaterials and nanotechnology, and the impact of size minimisation to a wide range of modern technologies. Using the nanostructure concept, students should be able to analyse the special mechanical, physical and chemical properties of nanomaterials. Students will also have the opportunity to evaluate and analyse the synthesis and processing techniques of nanomaterials, and master the methods to apply nanomaterials and nanotechnology in energy and environment industries. (Capability 1.1, 2.1, 2.2, 3.1, 3.2, 4.1, 4.2, 5.1 and 6.2)
  5. Demonstrate an understanding of Powder Metallurgy: Student will understand the basic principles of powder metallurgy parts production, its importance and limitations; Understand the key parameters of powder metal processing, in particular metal injection moulding; Understand the fundamentals of solid-state sintering; understand the relationship between the microstructure and mechanical properties of powder metallurgy components. (Capability 1.1, 2.1, 2.2, 3.1, 3.2, 4.1, 4.2 and 5.2)
  6. Demonstrate an understanding of Advanced Manufacturing Technology: Students should learn the general work process for digital design and material transformation, e.g. the additive manufacture (AM). Understand its advantages and limitations over the traditional subtractive manufacturing. Learn the different forms of materials and solidification method/process of 7 types of additive manufacturing, post processing and quality control, especially the process strategy for powder-based systems in AM. (Capability 1.1, 2.1, 2.2, 3.1, 4.1 and 5.2)
  7. Demonstrate an understanding of the Sustainable manufacturing: Student will be able to describe the difference between traditional manufacturing and sustainable manufacturing technologies, and three dimensional aspects of sustainable manufacturing. Evaluate the sustainability of manufacturing technologies, and understand how to transfer a linear economic system to a circular economic system with incorporating 6R methodology. Describe four layers of sustainable manufacturing. Understand basic steps of product life-cycle assessment, and its application. (Capability 1.1, 2.1, 2.2, 3.1, 3.2, 4.1 and 5.2)
