What is Metal Finishing?

The Institute has retained its title of The Institute of Metal Finishing despite numerous discussions at Council and elsewhere aimed at finding an alternative title that would be more appropriate to cover the whole field of activities in which the Institute is involved.

The IMF logo is so well known that change has always been rejected. Surface Technology, Surface Engineering, Materials Finishing are all examples of alternative suggestions that have been considered as fashion has changed.

Regardless of the title, the Institute is concerned with any process that modifies the surface of a material or any process that applies a coating to the surface of a material to confer new properties. Coating processes can also be used to produce freestanding articles e.g. by electroforming. The most well known processes are shown here.
