Abstract: A method and class of bond coat is provided that physically and chemically bonds solid layer lubricants and other functional coatings to a substrate by burnishing, for example, selected soft materials, including oxides such as antimony trioxide, against the substrate. The new method and bond coat is a major improvement over conventional bonding or coating methods. The process is non-vacuum at ambient temperatures, requiring no binders, adhesives, curing or baking. Lubricant performance can be enhanced by orders of magnitude compared to when the bond coat and burnishing process are not applied. The method is inexpensive, environmentally friendly, applicable to any substrate material, and scalable.

Abstract: A filtered cathodic-arc plasma source of lower plasma losses and higher output plasma current to input current efficiency is disclosed. Plasma filtering is accomplished in a right angle bend magnetic filter arranged to include the effects of at least three added magnetic coils located at the right angle bend of the filter path. These magnetic coils and other filter attributes, including an array of transverse fins and a magnetic cusp trap in the filter path, achieve desirable magnetic flux paths, lower plasma collision losses and reduced undesired particle output from the plasma filter. Multiple cathode sources, multiple plasma output ports, Larmour radius influence, equipotential magnetic flux lines and electron/ion interaction considerations are also included in the plasma source. Application of the plasma source to film coating processes is included.

Abstract: Formation of for example yttria stabilized zirconia films of significant 001 orientation on a variety of substrates including amorphous material and room temperature limited material is disclosed. The yttria stabilized zirconia film formation is achieved using pulsed laser ablation of a polycrystalline yttria stabilized zirconia target source while the substrate is electrically biased, disposed at a selected angle and maintained at substantially room temperature in the presence of an argon atmosphere. The film formation uses low bias voltage, requires no ion beam apparatus and employs low temperatures sufficient only to enable process stabilization. Film formation is accomplished in a step sequence wherein each step responds to temporal and spatial component segregations occurring in a laser-ablated ion plume.

Abstract: Process control for generating graded multilayer films repetitively and consistently using both pulsed laser sputtering and magnetron sputtering deposition techniques. The invention includes an apparatus which allows for set up of an ultrahigh vacuum in a vacuum chamber automatically, and then execution of a computer algorithm or "recipe" to generate desired films. Software operates and controls the apparatus and executes commands which control digital and analog signals which control instruments.
