This course teaches technicians how to select, test and process materials that are locally available and repairable. It covers metals, polymers, ceramics, composites, heat treatment, corrosion and the material-selection judgement needed to build appropriate technology for Zimbabwean conditions.
Organised into 6 weeks. Weekly quizzes and a final test consolidate learning.
