Metallography & Microscopy

The National Composites Centre (NCC) is delighted to work in collaboration with the AMRC to deliver this course.

This course is being run at The National Composites Centre by AMRC - BOOK HERE

Course aims
This course provides an insight into the techniques used for sample preparation and the operation of optical and scanning electron microscopes. It describes the equipment and methods for extracting samples from metal items, for producing flat surfaces and etching to reveal surface features. The principles on which both types of microscope operate and examples of the images and information that can be obtained are explained.

Who should attend
The course is suitable for after-sales professionals, laboratory staff, marketing and sales professionals in all sectors of engineering. Sectors include, for example, aerospace, automotive, conventional powergen, nuclear and renewable energy. A basic understanding of science and engineering principles is assumed.

Course Duration: One day

Price: £400
