Industrial Wear Applications of Advanced Ceramics
International Syalons has utilised the outstanding wear resistant properties of advanced silicon nitride and sialon ceramics for diverse industrial wear applications for over 30 years.
Sialons are silicon nitride based ceramic alloys and can be tailor-made to suit a vast range of applications where wear resistance is required. Syalon 101 is possesses an outstanding set of physical properties such as high strength, toughness and hardness and is pre-eminently suitable for couples used in sliding wear or as dewatering foils in paper manufacture, whilst the superior hardness of Syalon 050 allows it to be of particular benefit in many wear applications, such as sand blast liners.
Zircalon, a partially stabilised zirconia, although generally not as wear resistant as Syalon, possesses superior toughness making it the material of choice for many wear applications where impact is experienced. For example, Zircalon has found wide use as weld locations pins in resistance welding of captive nuts to sheet metal.
Below are a selection of common industrial wear applications of our sialon and zirconia fine ceramics.
-
Milling Media
When used as grinding vessels for the preparation of industrial and analytical samples, weight losses for Syalon 101 bowls are about 14 per cent of the reported weight loss for agate, alumina, zirconia and tungsten carbide. Milling efficiencies are also in general improved.
-
Shot Blast Nozzles
In shot blasting applications, particularly with aggressive grits, Syalon 050 out-performs conventional nozzles with a useful life of about eight times that of conventional nozzles. Syalon nozzles are light weight and easy to handle.
-
Paper Dewatering Foils
During the dewatering stage of modern paper manufacture, the paper travels over the de-watering foils at speeds approaching 100km⁄min, making only the most wear and thermal shock resistant materials, such as Syalon 101, applicable.
