Metallurgy

The course is divided into 4 parts. One concerns the metallurgy of iron / steel and their alloys The second reffers to the surface metal working techniques and their industrial applications in combination with examples of their theoretical study. The third concerns the protective coatings of metals and of the reasons for their application, advantages and give the divisions and their suitability. The latter refers to the Thermal and thermochemical processing steel fluidised bed.

Objectives

At the end of this course the student should: - Be able to apply physical and chemical methods of extracting metals from their ores - Be able to regulate the process variables such as temperature etc. mixtures of raw materials for the production of metals - Be able to conduct studies in metals and alloys before and during treatment to determine their properties - Be able to supervise / carry samples from various stages of processing for laboratory analyzes and tests - Be able to examine the metal processing techniques to verify the quality and improve the processing or the development of new methods - Be able to investigate whether the methods used are economical, efficient and environmentally acceptable

Prerequisites

The student should have knowledge of math, chemical thermodynamics and physical chemistry
