MTE5883 · Environmental durability and protection of metals and engineering materials

Overview

This unit covers the manifestations and types of corrosion usually found in the field in areas such as marine, chemical, manufacture, transport and offshore industries. Emphasis will be placed on identification and recognition of the types of corrosion likely to occur and then develop strategies to mitigate corrosion. The mechanisms of corrosion in some environments will also be studies. This includes stress corrosion cracking, microbiologically-induced corrosion and corrosion in reinforced concrete structures. Corrosion mitigation mechanisms will be discussed. This includes materials selection, cathodic protection, coatings and inhibitors. The unit will also cover cement and concrete, including reinforced concrete and topics related to durability of non-metals.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains threshold hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

1. Assess corrosion mechanisms that are prevalent in engineering alloys used in diverse service environments in order to develop methods to mitigate corrosion.
2. Evaluate corrosion and environmentally-assisted cracking performance of engineering alloys used in industrial applications to recognise alloy design principles.
3. Draw on advanced electrochemical methods to predict durability of coatings that protect engineering alloys.
4. Engage with peers in a team and analyse complex theories related to corrosion of engineering alloys, and appreciate how they guide material testing standards and materials selection in various industries.
5. Manage workload and reflect upon the effectiveness of a team's performance in problem-solving tasks.
6. Interpret advanced concepts/theories/methods related to corrosion and communicate them to a broader audience.
7. Reflect on classical corrosion and environmentally-assisted cracking mechanisms and apply them in the context of materials selections for engineering applications.

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours of independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.
