Study on the fundamental causes of metal corrosion in animal buildings: Field and chamber tests
This thesis discusses in detail the corrosion mechanisms of metal products exposed for a period of two years in three animal buildings and one environmentally controlled building based on the analyses of the surface corrosion products using advanced surface analysis techniques. It includes not only research on the classic corrosion of metals but on the microbial-induced corrosion, which is a new area in the study of metal corrosion in animal buildings. Another feature of the thesis is a thorough study of the test environments that makes it possible to relate the corrosion mechanisms to the environments where the metals were placed. In order to conduct more controlled studies on the effect of either individual or combined factors on corrosion, a two-month simulation chamber test was carried out with ammonia being the variable, which yielded valuable information that ammonia might retard, instead of enhancing, corrosion process for uncoated 1010 carbon steel.
