Electrochemical etching tailors topography of a nanocrystalline or amorphous metal or alloy, which may be produced by any method including, by electrochemical deposition. Common etching methods can be used. Topography can be controlled by varying parameters that produce the item or the etching parameters or both. The nanocrystalline article has a surface comprising at least two elements, at least one of which is metal, and one of which is more electrochemically active than the others.

Gas metal arc welding (GMAW) is a widely used process for joining metals. Its main advantage over its competition gas tungsten arc welding (GTAW) is its high productivity in depositing metals. However, to melt metal from the wire to deposit into the work-piece, additional heat is consumed and applied to the work-piece with an uncontrolled fixed proportion to the effective heat that melts the wire. Such additional heat is often in excess of the needed heat input for the work-piece. The side-effects include a waste of the energy, an increased distortion, and possible materials property degradation. This invention is to device a method to transfer this part of heat to melt the wire by adding two wires, which form a pair of arc spots, under a tungsten arc. It also devices a method to assure the arc between the two wires be maintained stable such that the transfer be successfully continuous. The successful continuous transfer improves the energy efficiency, eliminates the adverse effects on the distortion and materials property, and decouples the controls on mass input and heat input on the work-piece.

A system and method for reducing attractive forces between a deposition mask and a substrate is provided that enables high-resolution direct deposition of a patterned layer of material on a substrate using electrostatic chucks for holding the substrate and the shadow mask. A charge-dissipating shadow mask is utilized that comprises a thin conductive layer on the surface of the membrane of the shadow mask. The conductive layer helps to dissipate the charge that accumulates on the membrane of the shadow mask, thereby reducing the attractive forces between the substrate and the shadow mask. As a result, the shadow mask and substrate can be placed in closer proximity to each other than would be possible without the charge-dissipating shadow mask, thereby reducing feathering effects and enabling higher resolution direct deposition.
