The disclosure relates to a method and apparatus for preventing oxidation or contamination during a circuit printing operation. The circuit printing operation can be directed to OLED-type printing. In an exemplary embodiment, the printing process is conducted at a load-locked printer housing having one or more of chambers. Each chamber is partitioned from the other chambers by physical gates or fluidic curtains. A controller coordinates transportation of a substrate through the system and purges the system by timely opening appropriate gates. The controller may also control the printing operation by energizing the print-head at a time when the substrate is positioned substantially thereunder.

An embodiment relates to an ultrasonic additive manufacturing process, comprising joining a foil comprising a bulk metallic glass to a substrate; and forming a cladded composite comprising the foil and the substrate; wherein a thickness of the cladded composite is greater than a critical casting thickness of the bulk metallic glass, wherein the cladded composite comprises a cladding layer of the bulk metallic glass on the substrate and the bulk metallic glass comprises approximately 0% crystallinity, approximately 0% porosity, less than 50 MPa thermal stress, approximately 0% distortion, approximately 0 inch heat affected zone, approximately 0% dilution, and a strength of about 2,000-3,500 MPa.

This invention relates to thermal spray coatings and processes onto non-smooth surfaces. The coating and processes can coat non-smooth surfaces without substantial degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The ability for coating fractional coverage to maintain the surface profile while maintaining wear resistance is unprecedented by conventional thermal spray processes.

There is provided a method of performing a surface treatment with respect to a metal mounting table for mounting a substrate to be plasma-processed, the mounting table functioning as a lower electrode configured to generate a plasma by a high frequency power applied between an upper electrode and the lower electrode. The method includes: performing a first surface treatment by spraying a non-sublimation blast material as a non-sublimation material onto a mounting surface of the metal mounting table on which the substrate is mounted, followed by a second surface treatment by spraying a sublimation blast material as a sublimation material onto the mounting surface.
