THE BEHAVIOR OF MATERIALS IN MECHANICAL SEALS AND BEARINGS IN A SEA WATER ENVIRONMENT

A systematic examination of the behaviour of selected materials for use in mechanical seals and bearings is described. The advantages and limitations of various materials are discussed with particular reference to the inter-relation of wear and friction with surface and bulk properties, the corrosion of matrix elements in cermet coatings, porosity of coatings leading to corrosion of the substrate and transfer of material between mating surfaces. It is concluded that the load carrying capacity of a sprayed or co-electrodeposited coating may be considerably modified by the physical properties of its substrate. Thus coatings applied to phosphor bronze or gunmetal substrates will tolerate far higher loads than similar coatings applied to high-strength stainless steels.
