INVESTIGATION OF BONDING IN OXIDE-FIBER (WHISKER) REINFORCED METALS.
Abstract
Special binary alloys of pure Ni containing 1 at.-% of Al, Cu, In, Ti, Zr and Cr were prepared and were used in sessile drop experiments, which were conducted at temperatures ranging between 1460 and 1510 C and at pressures of 5 x 10 to the -5th power Torr. It was found that the additions of Al, Cu, and In had little effect in lowering the contact angle between pure Ni and single crystal substrates of alpha-Al2O3. However, the Ti, Zr and Cr additions, which reacted chemically with the substrate, lowered the contact angle significantly. Future studies are planned which will study the effect of interfacial reactions on the bond strength between the Ni/Ni alloys and alpha-Al2O3. (Author)
