Silicon Carbide Whisker/Alumina Matrix Composites: Effect of Whisker Surface Treatment on Fracture Toughness Author: Joseph Homeny Wallace L. Vaughn Mattison K. Ferber

Journal: Journal of the American Ceramic Society

Issue Date: 1990

Abstract(summary):
The fracture toughness of a 30 vol.% SiC whisker/Al 2O 3 matrix composite was evaluated as a function of whisker surface chemistry. Two types of SiC whiskers (Silar-SC-9 and Tateho-SCW-1-S) were investigated. Modification of the whisker surface chemistry was achieved by subjecting the whiskers to thermal treatments under controlled atmospheres. Whisker surface chemistry, as determined by X-ray photoelectron spectroscopy, was correlated to the fracture toughness of the composites
