WATER EFFECT ON CORROSION BEHAVIOUR OF STRUCTURAL CERAMICS
MRS bulletin, Vol.19(10), pp.39-45
01 Jan 1994
Abstract
The effects of water on the stability and mechanical behaviour of typical oxide (Al2O3,ZrO2) and non-oxide (SiC,Si3N4,B4C,AlN,BN) structural ceramics are considered. Some deleterious effects of water are chemical corrosion near ambient temperature, stress corrosion, water-assisted degradation of zirconia, high-temperature oxidation of non-oxide ceramics in water vapour and hydrothermal corrosion. Mechanical properties can be affected by chemisorption of water, dissolution of the grain-boundary phase, or preferential dissolution of stressed regions around a crack tip. Beneficial effects of water include improved tribological behaviour and reduced wear and friction coefficients, and the production of carbon films on reinforcements for composites by hydrothermal leaching of SiC. 69 refs.
