CHEMMAT 754 : Materials Performance Enhancement
Engineering
2020 Semester Two (1205) (15 POINTS)
Course Prescription
Course Overview
This is a NZQF Level 9 elective paper after CHEMMAT 121, 204 and 305. Materials are often needed 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 including chemical processing industry. This paper also covers new development of materials including Nanomaterials and Nanotechnology, and Advanced Manufacturing Technologies such as Additive and Sustainable/Green Manufacturing.

Student should be able to evaluate and analyse various coating and thin film technologies, including traditional techniques and modern physical and chemical vapour deposition methods. Building on the knowledge from CHEMMAT 121 and 204, students should be able to use surface microstructure characterisation and microanalysis methods to analyse the surface properties and application cases. (Capability 1.1, 2.1, 2.2, 3.1, 3.2, 4.1, 4.2 and 6.1)
- Demonstrate and apply knowledge on Tribology, Friction and Wear of Materials: Students 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, 3.1, 3.2, 4.1 and 4.2)
- Understand and critically evaluate Nanomaterials and Nanotechnology: Students are required to understand 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 and 5.1)
- Understand and apply knowledge of Powder Metallurgy: Student will be able to understand the basic principles of the powder metallurgy part production, its importance and limitations, and use the key parameters of powder metal processing, in particular metal injection moulding; Understand the fundamentals of solid-state sintering; understand and analyse 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 and 4.2)
- Learn and understand 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, 3.1, 4.1 and 6.1)
- Learn and understand Sustainable manufacturing: Students will be able to describe the difference between traditional manufacturing and sustainable manufacturing, 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, 3.1, 4.1 and 6.1)

Learning Resources
Digital Resources
Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).
Please remember that the recording of any class on a personal device requires the permission of the instructor.
Academic Integrity
The University of Auckland will not tolerate cheating, or assisting others to cheat, and views cheating in coursework as a serious academic offence. The work that a student submits for grading must be the student's own work, reflecting their learning. Where work from other sources is used, it must be properly acknowledged and referenced. This requirement also applies to sources on the internet. A student's assessed work may be reviewed against online source material using computerised detection mechanisms.
Learning Continuity
In the event of an unexpected disruption we undertake to maintain the continuity and standard of teaching and learning in all your courses throughout the year. If there are unexpected disruptions the University has contingency plans to ensure that access to your course continues and your assessment is fair, and not compromised. Some adjustments may need to be made in emergencies. You will be kept fully informed by your course co-ordinator, and if disruption occurs you should refer to the University Website for information about how to proceed.
