Semester 1UWA (Perth)Face to face
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.
Students are able to (1) describe the fundamental mechanisms of corrosion and wear damage of engineering materials; (2) explain the common forms of corrosion and wear that occur in various industrial environments; (3) describe common laboratory and field testing techniques for corrosion and wear; (4) design and evaluate cathodic protection systems for simple engineering structures; (5) conduct materials selection and evaluate performance for corrosion and wear resistant applications; (6) work effectively in teams and as an individual to solve engineering problems; and (7) write technical reports to a professional standard and format.
Indicative assessments in this unit are as follows: (1) group assignment and field; (2) mid-semester test; and (3) a 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 via the Booktopia Textbook Finder, which has the functionality to search by course code, course, ISBN and title, and may also be posted or available at the appropriate school's administrative offices. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
