US Patent:

6348687, Feb 19, 2002

Filed:

Sep 10, 1999

Appl. No.:

09/394185

Inventors:

John E. Brockmann - Albuquerque NM
John R. Torczynski - Albuquerque NM
Ronald C. Dykhuizen - Albuquerque NM
Richard A. Neiser - Albuquerque NM
Mark F. Smith - Albuquerque NM

Assignee:

Sandia Corporation - Albuquerque NM

International Classification:

H01J 4104

US Classification:

250251, 250288, 436173

Abstract:

A new type of aerodynamic particle beam generator is disclosed. This generator produces a tightly focused beam of large material particles at velocities ranging from a few feet per second to supersonic speeds, depending on the exact configuration and operating conditions. Such generators are of particular interest for use in additive fabrication techniques.

International Classification:

B05D 108

US Classification:

427449, 427453, 427456

Abstract:

The cylinder walls of light metal engine blocks are thermally spray coated with a ferrous-based coating using an HVOF device. A ferrous-based wire is fed to the HVOF device to locate a tip end of the wire in a high temperature zone of the device. Jet flows of oxygen and gaseous fuel are fed to the high temperature zone and are combusted to generate heat to melt the tip end. The oxygen is oversupplied in relation to the gaseous fuel. The excess oxygen reacts with and burns a fraction of the ferrous-based feed wire in an exothermic reaction to generate substantial supplemental heat to the HVOF device. The molten/combusted metal is sprayed by the device onto the walls of the cylinder by the jet flow of gases.

International Classification:

C25D 1302

US Classification:

204484

Abstract:

Electrophoretically active sol-gel processes to fill, seal, and/or density porous, flawed, and/or cracked coatings on electrically conductive substrates. Such coatings may be dielectrics, ceramics, or semiconductors and, by the present invention, may have deposited onto and into them sol-gel ceramic precursor compounds which are subsequently converted to sol-gel ceramics to yield composite materials with various tailored properties.
