Interface Reaction between Nd₂O₃ and Alumina Single Crystal

Abstract:

A kind of high alumina content ceramic stand wear and tear has been designed. The interface chemical reaction between single crystal alumina (in order to eliminate the influence of grain boundaries) and Nd₂O₃ powder has been observed. Microstructure and wear rate of the ceramic were investigated by SEM and by a purposely designed experimental device for the measurement of wear rate. Perimental results showed that a rare earth aluminate formed on the interface and the wear rate of a sample has reduced by 34%. The newly formed compound and single crystal alumina formed a compact structure which could make the grain boundaries strengthened and also lead to a beneficial effect on the elimination of pore and the density of the ceramic, at the same time improve abrasive resistance.
