Corrosion: Mechanism and Protection
About The Course
Corrosion naturally takes place in everyday life, including in industry equipment. Without protection it will cause hard financial loss. The course is conducted with two objectives: firstly, provides understanding on why and how corrosion occurs and secondly provides know how in controlling and preventing corrosion. This 3-days course provides an excellent avenue for participants and those who involved in failure analysis to update their appreciation of corrosion and the awareness of the emerging technologies for corrosion control, prevention, testing and monitoring.
Design for
Corrosion practitioners, designers, technical managers, inspection and maintenance engineers, and quality control personnel.
