Application
This unit of competency defines the skills and knowledge required to apply engineering metallic/ceramic coatings to ferrous and non-ferrous metals and some non-metallic materials, e.g. plastics.
It applies to producing engineering coatings designed to promote wear resistance, protect against corrosion, and reclaim worn components. It also applies to manufacturing components (electroforming).
Where pre-treatment operations only are required unit MEM08002 Pre-treat work for subsequent surface coating should be selected.
Where straightforward operation of electroplating process is required unit MEM08003 Perform electroplating operations should be selected.
Where surface preparation operations are required unit MEM08011 Prepare surfaces using solvents and/or mechanical means and unit MEM08012 Prepare surfaces by abrasive blasting (basic), should also be selected as appropriate.
Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.
Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.
Where basic inspection of completed or partly completed products produced by others is required unit MEM15004 Perform inspection should also be selected.
Where the selection and use of power tools/hand held operations is required unit MEM18002 Use power tools/hand held operations should also be selected.
Where construction of anodes, shields/robbers is required appropriate fabrication units should also be selected.
Where dogging/lifting is required appropriate materials handling units to suit regulatory requirements should also be selected.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
