Nano-Crystalline Diamond Films Synthesized at Low Temperature and Low Pressure by Hot Filament Chemical Vapor Deposition.

Relevancy:  

Nano-crystalline silicon thin films grown by the inductively coupled plasma assisted CFUBM at low temperature.

Relevancy:  

Nano-crystalline Zr2ON2 thin films deposited by reactive magnetron sputtering.

Relevancy:  

Nano-crystalline, homo-metallic, protective coatings.

Relevancy:  

Orthopaedic prosthesis having at least one metallic component that includes a metallic substrate on which an integrally formed nano-crystalline coating is formed. The coating and the substrate have at least one metallic constituent in common having an average atomic concentration in the coating that differs from an average atomic concentration in the substrate by less than about 10 percent. Further, the nano-crystalline coatings includes crystalline grains with an average size in a range of about 1 to 999 nanometers, and more preferably in a range of about 10 to 200 nanometers. A transition region that exhibits a graded reduction in average grain size separates the coating from the substrate. The coating advantageously exhibits an enhanced hardness, and a high degree of resistance to corrosion and wear. In one application, the nano-crystalline coatings of the invention are utilized to form articulating surfaces of various orthopedic devices.

Nano-dispersion hardened chromium coatings - an alternative to electroplating

Relevancy:  

Composite coating of PVD in which second phase consists of Cr nitride nanoparticles. Graph shows hardness of "cerid 6i as function of heat treatment, where HV (0.1) is virtually constant at 1100 to 700°C. By contrast, electroplated Cr is formed at HV1400, softening such that at 250°C it has decreased to 700 HV. Table lists main features of title coating incl. excellent adhesion and resilience to bending & stretching. Comments on corrosion resistance. Typical applications incl. roller bearings. gearwheels. high pressure pumps, valve stems and coating for knives and cutting edges, use in truck engines etc. Table lists applications, materials, coating, hardness, thickness. Mass production methods in combination with plasma processes are noted.

Nano-dispersion hardened chromium deposits with tailored properties

Relevancy:  

Composite coatings, formed either by PVD or CVD or by electrodeposition of electroless deposition in which nano-particles are incorporated such as titanium nitride, carbonitride, chromium nitride, carbide, diamond & related carbon-based substrates (vacuum coated) or nickel, chromium, gold, platinum, cobalt, tin, palladium, silver with second phase particles such as silicon carbide or alumina. The means by which second phase particles can be chosen for given hardness, toughness etc is described with simple theory. Graph shows hardness increasing with ceride particle content to 1700 HV 0.1. General discussion of hardness, bending & stretching (tensile); effects of operating temperature (chromium-matrix) on hardness. Examples of applications, incl. high pressure pumps, cutting tools, diesel engine components.

Nano-fiber arrayed surfaces.

Relevancy:  

Surfaces are provided comprising an array of partially embedded nano-fibers. Two such surfaces may contact each other such that the respective nano-fibers contact at orthogonal angles, resulting in ultra-low friction and ultra-low adhesion contact. Such configurations are useful in several NEMS or MEMS applications, as well as macro-sized applications. Alternatively, the surfaces may contact each other such that the respective nano-fibers are parallel. These configurations are useful in micro-stage or high-order three- dimensional self assembly applications.

Nano-Grain Structure of Nickel Films Prepared by Emulsion Plating using Dense Carbon Dioxide.

Relevancy:  

SURF A nanocrystalline nickel film was prepared by electrodeposition in a constantly agitated ternary system of dense carbon dioxide (CO2) and electrolyte with a surfactant. The average grain size of the plated Ni film was 11.1 nm. In contrast, a nickel film prepared from an electroplating solution by a conventional method without the use of surfactant had an average grain size of about 19.8 nm. The Vickers hardness of the film obtained by the new method was about 680 Hv, while that prepared from the electroplating solution alone was only about 550 Hv. It is deduced that grain-size strengthening was observed in the electroplated film obtained using this emulsion system.
