10131969 · 2018-11-20 · ·

Method for forming an oxide dispersion strengthened alloy. An alloy material (24) is melted with an energy beam (28) to form a melt pool (30) in the presence of a flux material (26), and particles (36) of a metal oxide are directed into the melt pool such that the particles are dispersed within the melt pool. Upon solidification, an oxide dispersion strengthened alloy (44) is formed as a layer bonded to an underlying substrate (20) or as an object contained on a removable support.

Method for the fabrication of corrosion resistant electrodes
10119935 · 2018-11-06 · ·

An electrode for use in instruments capable of measuring the electrophoretic mobility of particles in solution is disclosed. The electrode is comprised of an inexpensive support member, generally made of titanium, onto a flat surface of which has been connected, generally by microwelding, a flat electrically conductive but chemically inert foil member, preferably platinum. A uniform texture can be generated on the exposed surfaces of the electrode by various means including tumbling the electrode with an abrasive. An oxide layer can be generated on the support member by soaking the composite electrode in an appropriate medium, protecting the exposed surface of the support member from fluid contact with the sample solution, while the foil member, unaffected by the oxidation process, is able to contact the sample solution.
