A heat exchanger is disclosed for transferring heat from a first material to a second material comprises a structural heat transfer member having a first surface in contact with the first material and a second surface in contact with the second material. The heat exchanger also has a coating on the first surface, the second surface, or on the first and second surfaces. The coating comprises filler particles dispersed in a polymer resin matrix.

Coated heat exchanger

An embodiment of an article includes a substrate and a conformal coating. The conformal coating includes a first particulate layer between a first matrix layer and a second matrix layer. The first particulate layer includes a first plurality of ordered inorganic particles spaced and distributed substantially uniformly throughout the first particulate layer, and a ceramic matrix material disposed between individual ones of the first plurality of particles.

Conformal composite coatings and methods

A method of joining includes bringing a bulk metallic glass (BMG) material to a temperature lower than the crystallization temperature of the BMG material and depositing the BMG material onto a first substrate with interlock surface features such that the BMG material interlocks with the interlock surface features of the substrate. The method includes joining a second substrate to the BMG material, wherein the second substrate includes interlock surface features such that the BMG material interlocks with the interlock surface features of both the first and second substrates, joining the first and second substrates together to produce a fully amorphous joint between the first and second substrates.

Material joining

There is a gear set. The gear set has a) a first gear having a first surface and b) an intermeshing second gear having a second surface. The first and second surfaces each, independently, have an isotropic arithmetic mean roughness, Ra, of about 0.0762 micrometers/3 microinches or less and are lubricated. There is also a method for increasing the contact surface-fatigue life of a gear set.

A method for depositing a protective coating on a complex shaped substrate includes the steps of: (1) dipping a complex shaped substrate into a slurry to form a base coat thereon, the slurry comprising an aqueous solution, at least one refractory metal oxide, and at least one transient fluid additive present in an amount of about 0.1 percent to 10 percent by weight of the slurry; (2) curing the dipped substrate; (3) dipping the substrate into a precursor solution to form a top barrier coat thereon; and (4) heat treating the dipped, cured substrate to form a protective coating.

A method for making a membrane electrode assembly includes the steps of providing a membrane electrode assembly including an anode including a hydrogen oxidation catalyst; a cathode; a membrane disposed between the anode and the cathode; and depositing a peroxide decomposition catalyst in at least one position selected from the group consisting of the anode, the cathode, a layer between the anode and the membrane and a layer between the cathode and the membrane wherein the peroxide decomposition catalyst has selectivity when exposed to hydrogen peroxide toward reactions which form benign products from the hydrogen peroxide. The peroxide decomposition catalyst can also be positioned within the membrane. Also disclosed is a power-generating fuel cell system including such a membrane electrode assembly, and a process for operating such a fuel cell system.

A seal assembly for a solid oxide fuel cell stack, includes at least two fuel cell stack components having opposed surfaces and a seal member disposed between the surfaces, wherein the seal member is a compliant seal member that is mechanically compliant in both in-plane and out-of-plane directions relative to the surfaces. The seal member is advantageously formed of one or more substantially continuous fibers. Further, preferred materials for the seal member are provided which advantageously allow for a desired level of impermeability while preventing contamination of the fuel cell stack.

A durable catalyst support/catalyst is capable of extended water gas shift operation under conditions of high temperature, pressure, and sulfur levels. The support is a homogeneous, nanocrystalline, mixed metal oxide of at least three metals, the first being cerium, the second being Zr, and/or Hf, and the third importantly being Ti, the three metals comprising at least 80% of the metal constituents of the mixed metal oxide and the Ti being present in a range of 5% to 45% by metals-only atomic percent of the mixed metal oxide. The mixed metal oxide has an average crystallite size less than 6 nm and forms a skeletal structure with pores whose diameters are in the range of 4-9 nm and normally greater than the average crystallite size. The surface area of the skeletal structure per volume of the material of the structure is greater than about 240 m/cm. The method of making and use are also described.
