An investigation into phenomena which influence the optimisation of ion plating systems
Ion plating involves the transportation of vapour through a low pressure glow discharge to form solid coatings on negatively biased substrates. Although the method has gained commercial acceptance, particularly for engineering applications, much of the underlying science of the process is poorly …

Optical absorption and anisotropy of refractory oxides fabricated by ion-assisted deposition and ion plating.
… determines their performance. Thickness variation due to the deposition process is well understood and correctable. Variation in the refractive index due to the deposition process is a considerably more complex problem. In this work two important members of the class of high index refractory …

Ion plated carbon films and their tribological properties
The conventional ion plating technique is described and the physicalmechanism and energies involved in the technique reviewed. The triode(assisted discharge) ion plating is studied and it is shown to increasethe ionization several times.Ion plating with a hollow cathode discharge is studied. The …

Microstructural studies of vapor-deposited nickel/ceramic composites
… fundamental aspects of metal/ceramic interactions through the analysis of model composites produced by plasma-assisted physical vapor deposition (ion plating) and consisting of thin ($<$1 micrometer) metallic films on a ceramic substrate. The two major aspects of this research are: (1) the …

Structure and properties of titanium nitride-strengthened microlaminate metal matrix composites
This investigation examines the structure and properties of titanium nitride strengthened microlaminate metal matrix composites. Reactive ion plated titanium nitride (TiN) was deposited onto titanium, nickel, and aluminum foils which were subsequently hot pressed to form microlaminate composites. …
