Content This unit addresses the damage and failure of materials and structures due to corrosion and wear, and relevant methods used to prevent such damage and failures. The unit covers topics including electrochemical fundamentals of corrosion; forms of corrosion; corrosion testing methods; corrosion control and prevention; corrosion-resistant materials; types of wear; wear mechanisms; wear-resistant materials; and control of wear through materials selection and design. The main contents include uniform, pitting, galvanic and crevice corrosion; intergranular corrosion and selective leaching; stress corrosion cracking and corrosion fatigue; high temperature oxidation and hydrogen embrittlement; corrosion testing methods and standards, corrosion control and prevention strategies and techniques; abrasive, adhesive, and erosion wear; and materials selection and design against corrosion and wear.
Outcomes Students are able to (1) work effectively in teams in projects to solve engineering problems; (2) write concise technical reports; (3) develop and practise enquiry-based thinking relevant to the discipline; (4) demonstrate information literacy and critical thinking (e.g., locate and evaluate sources of information for projects and some of the relevant unit contents); (5) apply problem-solving and logical thinking skills; (6) learn and understand the fundamental science of corrosion and wear degradation of engineering materials; (7) identify and understand common forms of corrosion and wear occurring in industrial environment, and use fundamental knowledge to analyse and diagnose corrosion and wear problems; (8) understand testing techniques and testing data interpretation for corrosion and wear; (9) design and evaluate cathodic protection systems; and develop corrosion protection strategies; (10) evaluate performance and conduct selection of materials for corrosion and wear resistant applications; and (11) formulate a solution to rectify/prevent the identified damage.
Assessment Typically this unit is assessed in the following ways: (1) team projects; (2) laboratory report; and (3) final examination. Further information is available in the unit outline.

Supplementary assessment is only available in this unit in the case of a student who has obtained a mark of 45 to 49 and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
