In-House Training Corrosion Courses

If you are concerned with corrosion in your company, in-house training or on-site training is a great solution to train a group of employees from design, production, operation, quality assurance, inspection and maintenance, and technical sales and support on corrosion control and corrosion prevention technology. The contents of all our corrosion courses can be customized to fit your organization's needs.

There is no limit to the number of participants required for in-house training corrosion courses. We conduct the in-house training corrosion course at your company's premises worldwide, and at a time convenient to your company.

Corrosion Course-On-Demand

All our publicly scheduled corrosion short courses are conducted once a year. However, you do not need to wait for one year if you have missed any of the publicly scheduled corrosion courses as we have this unique corrosion course-on-demand scheme: we will conduct the course just for you (on an one-on-one basis) or for a small group from your company at a time and in a location convenient to you. This option costs significantly less than a full-scale in-house or on-site corrosion training program.

PowerPoint Slides and Test Banks for Trainers, Instructors, Tutors, University Lecturers and Professors

If you are involved in teaching corrosion courses, you may wish to purchase a complete set of PowerPoint slides and the computerized test banks (in MicroTest format) with solutions. These presentations are suitable for teaching corrosion courses at different levels (from undergraduate to postgraduate) and durations (from 6 hrs to 40 hrs). These ready-to-use corrosion PowerPoint slides contain high quality color photographs, illustrations, animations and video clips. They can also be easily edited and customized to your own styles. The corrosion test banks contain over 1,000 corrosion questions for your use in tutorials, tests or examinations. These questions are conveniently grouped into 4 categories in the test bank: (1) true or false, (2) multiple choice, (3) calculation, and (4) reasoning and open-ended discussions).
