Tiivistelmä
The objective of the thesis is to study corrosion of the screws in a base station after 720 h salt spray test. Screws with different coatings were tested and the performance is compared to the current solutions.
The corrosion in general has both economical and quality influence on the final product. By se-lecting proper screws to the right environment, lots of costs are saved. Additionally possible qual-ity problems are minimized, which enhances the competitiveness of the product in many levels.
The testing of the screws cover both mechanical and visual tests in order to secure the selection of the best possible solution. The possible failure analysis of each solution takes place as well. It is important to have a systematic approach to recognize and mitigate corrosion problems.
The target of the thesis is also to make sure that the test results support the screw selection. It is also important that the test results correlate with the requirements
