A compressor is disclosed, including an outer casing and a fluid guide around a cavity within the casing. An inlet is in operative fluid communication with the cavity, and an outlet is also in operative fluid communication with the cavity. A prime mover includes an actuator disposed in the cavity. The actuator includes a surface arranged to receive fluid in the cavity from the inlet, impart compression to received fluid in the cavity, and discharge compressed fluid to the outlet. A surface of the compressor includes a cladding of a second aluminum alloy over a core of a first aluminum alloy, wherein the second aluminum alloy is less noble than the first aluminum alloy and includes an alloying element selected from tin, indium, gallium, or combinations thereof.

Aluminum compressor with sacrificial cladding

A heat transfer system is disclosed that includes a heat transfer fluid circulation loop, and also a heat exchanger that includes an aluminum alloy exterior surface having thereon a top surface coat derived from a composition comprising a trivalent chromium salt and an alkali metal hexafluorozirconate.

Aluminum heat exchanger

A sealing process includes applying a first reactant to a substrate having a porous structure, the first reactant comprising a chromium (III) precursor and a transition metal precursor and applying a second reactant to the first reactant, the second reactant comprising a rare earth element precursor and an alkaline earth element precursor to form reservoirs of trivalent chromium in pore space of the porous structure, and a physical barrier over the substrate and the reservoirs.

Sealing process for an anodized aluminum-alloy surface

A heat exchanger is disclosed. The heat exchanger includes a hollow tube extending from a tube inlet to a tube outlet. The hollow tube includes a wall that includes a core of a first aluminum alloy, and a cladding over the core of a second aluminum alloy. The second aluminum alloy is less noble than the first aluminum alloy and includes an alloying element selected from tin, indium, or gallium, or combinations thereof. A first fluid flow path is disposed along an inner surface of the wall from the tube inlet to the tube outlet, and a second fluid flow path is disposed across an outer surface of the wall.

A method is disclosed for treating an anodized metal surface. According to the method, polynuclear clusters comprising aluminum oxide hydroxide are applied to the anodized metal surface.

Treated anodized metal article and method of making

An additive manufactured workpiece includes one or more cavities having an inner surface. A dielectric interface is formed in the cavity, and conforms to the inner surface. The additive manufactured workpiece further includes an in-situ electrode in the cavities. The dielectric interface is interposed between the in-situ electrode and the inner surface of the workpiece.

Electrical discharge machining system including in-situ tool electrode

A method of applying a protective coating with improved adhesion on an aluminum alloy component includes first pretreating the surface of a component by depositing a sacrificial protective immersion layer using a zincating or similar process. Portions of the protective immersion layer as well as portions of the underlying aluminum alloy substrate are then electrolytically etched off in an ionic liquid. A protective aluminum coating is then electrodeposited on the component in an ionic liquid.

Sacrificial coating and procedure for electroplating aluminum on aluminum alloys

A method of growing a hierarchically structured anodized film to an aluminum substrate including growing a Phosphoric Acid Anodizing (PAA) film layer to an aluminum substrate and growing a multiple of Tartaric-Sulfuric Acid Anodizing (TSA) film layers under the Phosphoric Acid Anodizing (PAA) film layer.

Hierarchically structured duplex anodized aluminum alloy

A heat exchanger is disclosed. The heat exchanger includes a hollow tube including a first aluminum alloy extending along an axis from a tube inlet to tube outlet. A first plurality of fins including a second aluminum alloy extends outwardly from an outer surface of the tube. A second plurality of fins including a third aluminum alloy extends outwardly from the outer surface of the tube, interspersed along the axis with the fins including the second aluminum alloy. The third aluminum alloy is less noble than each of the first aluminum alloy and the second aluminum alloy, and includes an alloying element selected from tin, indium, gallium, or combinations thereof. A first fluid flow path is disposed through hollow tube from the tube inlet to the tube outlet. A second fluid flow path is disposed across an outer surface of the hollow tube through spaces between adjacent fins.

Aluminum heat exchanger with fin arrangement for sacrificial corrosion protection

A method of disposing a corrosion resistant system to a substrate may comprise applying a plating material to the substrate; forming a chemical conversion coating solution by combining a solvent, at least one corrosion inhibitive cation comprising at least one of zinc, calcium, strontium, magnesium, or aluminum, at least one corrosion inhibitive anion comprising at least one of phosphate, molybdate, or silicate, and a complexing agent; and applying the chemical conversion coating solution to the plating material on the substrate.
