Demonstrate advanced knowledge of engineering materials and identify types of corrosion.
- Learning Outcomes
- 1.Demonstrate knowledge of processing technology.
2.Identify standard types of corrosion.
3.Demonstrate knowledge of powder metallurgy
- Casting processes (including billet casting, direct chilled (DC) casting, continuous casting; foundry casting - sand, shell mould, die, permanent mould, lost wax) are described in terms of structural changes (including dendrites, grain size, phase type, segregation, super cooling, solidification).
Heat treatment processes (including annealing, homogenising, stress relieving, sub-critical annealing, normalising, hardening, tempering, solution and precipitation hardening)are described in terms of structural changes (including ferrous and non-ferrous equilibrium diagrams, phases and phase changes, transformation in micro structure, martensitic transformation, transformation diagrams, precipitation hardening, recrystallisation).
Mechanical processing of metals (including rolling, forging, extruding, drawing, bending, sintering) is described in terms of structural changes (including recovery, recrystallation, grain growth, texture, fibre, work hardening).
Metallic samples are selected, and types of aqueous corrosion are identified and differentiated by name (including general, galvanic, pitting, crevice, stress corrosion cracking, hydrogen embrittlement, selective leaching, intergranular, impingement).
Metallic samples are selected, and types of high temperature degradation are identified and differentiated by name (including oxide formation, adherence of oxide, oxide breakdown).
Systems for the prevention and control of corrosion on metals are selected (including cathodic protection, passivation, material selection, organic and inorganic coating systems).
