Abstract: A workpiece and associated method includes fabricating, employing an additive manufacturing process, a raw workpiece from aluminum alloy that includes silicon; heat-treating the raw workpiece to produce an intermediate workpiece, including subjecting the raw workpiece to a first temperature environment, wherein the first temperature environment agglomerates silicon particles disposed on a surface of the raw workpiece; cleaning the intermediate workpiece without removing the silicon particles agglomerated on the surface thereof; and applying a conversion coating onto the surface of the intermediate workpiece.

Abstract: A method for processing a raw workpiece into a final workpiece is described, wherein the raw workpiece includes a metallic structure including silicon particles dispersed therein. The raw workpiece is fabricated employing an additive manufacturing process, in one embodiment. The method includes heat-treating the raw workpiece to produce an intermediate workpiece, wherein the heat-treating includes subjecting the raw workpiece to a first temperature environment for a time period to produce an intermediate workpiece to form agglomerated silicon particles, wherein the agglomerated silicon particles are disposed on a surface of the raw workpiece. The method further includes removing the agglomerated silicon particles that are disposed on the surface of the intermediate workpiece.

Abstract: A surface treatment method for aluminum parts to improve adhesion of organic finishes to be applied to the aluminum parts is described. The method includes cleaning the aluminum part, deoxidizing the aluminum part, applying a conversion coating to the part, and rinsing the part in hot de-ionized water.

Abstract: A tank arrangement particularly adapted for processing parts in chemical milling operations, especially for circulation of water-base maskant fluid. The system includes a tank containing up-flow and down-flow draft tubes, each containing a low speed, high volumetric displacement impeller which minimizes shear stresses imparted on the maskant liquid. The up-flow tube provides circulation and establishes rapid surface flow velocities to prevent congealing of maskant liquid and the down-flow tube provides localized circulation and produces a fluid elevation change. A weir is provided at the top of each of the draft tubes, the use of which combined with the low speed impellers break up and disperse entrained air. The draft tubes include baffle plates suitably located to prevent the formation of vortices above, within and below the tubes. Adjustable fluid flow deflector plates are provided adjacent to the lower ends of the draft tubes to eliminate "dead spots" in the tank work zone.
