Abstract

Systems and methods are described for rapidly forming precision metallic and intermetallic alloy net shape parts directly from liquid metal droplets. A directed droplet deposition apparatus includes a crucible with an orifice for producing a jet of material, a jet destabilizer, a charging structure, a deflector system, and an impact zone. The systems and methods provide advantages in that fully dense, microstructurally controlled parts can be fabricated at moderate cost.

Process for forming one or more substantially pure layers in substrate material using ion implantation

Patent Musket, Ronald G. ; Brown, David W. ; Munir, Zuhair A.

A process is disclosed for forming a substantially pure layer of an implantable element in a substrate material by (a) selecting an implantable element and a substrate material to be implanted which, at the temperatures to be used, have limited mutual solubility in one another and do not form any intermediate phases with one another; (b) implanting a sufficient amount of the implantable element in the substrate material to permit formation of the desired substantially pure layer of the implantable element in the substrate material; and (c) annealing the implanted substrate material to form the desired layer.

Patent Musket, Ronald G. ; Brown, David W. ; Munir, Zuhair A.

A process is disclosed for forming a substantially pure monocrystalline layer of an implantable element in a monocrystalline substrate material by (a) selecting an implantable element and a monocrystalline substrate material to be implanted which, at the temperatures to be used, have limited mutual solubility in one another and do not form any intermediate phases with one another; (b) implanting a sufficient amount of the implantable element in the substrate material to permit formation of the desired substantially pure layer of the implantable element in the substrate material; and (c) annealing the implanted substrate material to form the desired layer.more »« less

Highly porous ceramic material and method of using and forming same

Patent Weimer, Alan W. ; Liang, Xinhua

The present invention generally relates to porous ceramic material and to methods of making and using the material. More particularly, the invention relates to methods of forming ceramic materials by depositing material, using atomic layer deposition, onto a sacrificial substrate and to ceramic materials having controlled wall thickness, relatively large pores, and high surface area by weight.

Methods and apparatus for altering material using ion beams

Patent Bloomquist, Douglas D. ; Buchheit, Rudy ; Greenly, John B. ; ...

A method and apparatus for treating material surfaces using a repetitively pulsed ion beam. In particular, a method of treating magnetic material surfaces in order to reduce surface defects, and produce amorphous fine grained magnetic material with properties that can be tailored by adjusting treatment parameters of a pulsed ion beam. In addition to a method of surface treating materials for wear and corrosion resistance using pulsed particle ion beams.
