Abstract: An ink jet printing system includes: a print head including multiple fluid ejectors, each fluid ejector including a corresponding nozzle defined in a bottom surface of the print head, each nozzle configured to eject a liquid onto a substrate. The nozzles can be arranged in an array including four or more parallel rows, the rows extending along a direction that is perpendicular to a process direction of the ink jet printing system. The process direction is the direction of relative motion between the print head and the substrate during operation of the print head. A spacing between adjacent nozzles in each row can be such that a nozzle density in each row is less than 75 nozzles per inch. A spacing between adjacent rows in the process direction can be less than the spacing between adjacent nozzles in each row.

Abstract: Methods for applying an amorphous metal alloy to a substrate, comprising the steps of vaporizing an amorphous metal alloy composition, in a plasma spray gun to form a metal alloy vapor plasma plume, directing the metal alloy vapor plume onto a cooled substrate, maintained and condensing and rapidly solidifying the amorphous metal alloy composition vapor on the substrate, to form an amorphous metal layer deposit of high density and strength.

Abstract: Methods and compositions relating to powder metallurgy in which an amorphous-titanium-based metal glass alloy is compressed above its glass transition temperature Tg with a titanium alloy powder which is a solid at the compression temperature, to produce a compact with a relative density of at least 98%.
