Amongst the applications for surface coatings used by these industries, different kinds of rolls feature very importantly. Here, it is essential that a good surface finish is maintained on the rolls in order that the quality of the product is maintained whatever the function.

Steam heated dryer cylinders and rolls are surface coated by thermal spraying and these may be treated in house by the applicator or, as in the case of the famous Yankee Drier Drums, which are typically 5 metres or more in diameter, have to be treated in situ.

Large Calender rolls which may be used in the final stages of production of special paper are required to have a high surface finish and are sprayed with hard wear resistant coatings such as Tungsten Carbide. After diamond wheel grinding and in some cases polishing, WC coatings may be finished to 2 micro inches (0,05 microns) or better.

In the print industry, Anilox rolls are sprayed with a ceramic material and laser engraved to produce a surface profile which will deliver a controlled amount of ink to the paper being printed.

Such rolls, and many other applications will be described by the speakers during the conference, illustrating how worn or scarred components may be salvaged to provide the surface texture required. Such repair operations not only save money by extending component life but also conserve natural resources and energy required in producing replacement components.

Other surfacing technologies such as Welding are also used extensively where coating strength and resistance to shock loading are required and applications using this technology are also covered in this conference.
