All oxide composites (reinforcement and matrix both being oxides) exhibit high temperature oxidation resistance in addition to high strength and hardness. A major drawback of these materials is that the oxide fiber and oxide matrix tend to react, whi

Earlier studies indicated that implantation of zirconium into sapphire at room temperature produced an amorphous layer at a critical composition of approximately 6.5% (cation). Further insight into the amorphization of sapphire has been provided by i

A new parameter, hardness/modulus2 (H/E2), has been derived from the equations used to calculate the hardness and elastic modulus from data taken during continuous depth-sensing microindentation tests. This paper discusses the use of this parameter t
Two ion implantation conditions were evaluated for improving the mechanical performance of sapphire IR window material. Both increased the average strength as measured by 4-point bend tests and were effective in preventing the propagation of surface

The principal features of the elevated temperature deformation processes of creep and superplasticity are reviewed. The features that may be strongly influenced by the ultra-fine microstructure are emphasized. It is concluded that creep resistance wi

Ion beam mixing of thin oxide films, Cr2O3 and ZiO2, on sapphire substrates has been studied. The systems were chosen according to their solubilities in α-Al2O3: Cr2O3 is completely soluble, while ZrO2 is insoluble. Mixing experiments were performed

Ion implantation of ceramics such as Al2O3 and SiC may produce a highly damaged but crystalline surface layer or an amorphous surface. The specific structure depends upon the implantation parameters. Studies using microindentation techniques show tha

Analytical electron microscopy (AEM) has been used to study ion beam mixing in an oxide-oxide system: ZrO2 thin films on α-Al2O3. This mixing process is useful in applications such as adhesion enhancement.Films of ZrO2 (∼80 nm thick) were deposite

Amorphous carbon films variously designated as i-C, α-C:H diamond-like or hard carbon films, have interesting optical and mechanical properties and are candidates for wear and corrosion protection in a wide range of applications. Because the depth o

In recent years, thin films and ion implanted layers have been the focus of much research. Such surface layers are used for a variety of applications in industry. For example, thin metallic films are used for electrical contacts and for diffusion bar
