An article includes a ceramic-based substrate and a barrier layer on the ceramic-based substrate. The barrier layer includes a matrix of barium-magnesium alumino-silicate or SiO, a dispersion of silicon oxycarbide particles in the matrix, and a dispersion of particles, of the other of barium-magnesium alumino-silicate or SiO, in the matrix.

Silicon oxycarbide environmental barrier coating

An article includes a silicon oxycarbide-based layer that has Si, O, and C in a covalently bonded network. The silicon oxycarbide-based layer has first and second opposed surfaces. A calcium-magnesium alumino-silicate-based layer is interfaced with the first surface of the silicon oxycarbide-based layer.

A method is disclosed for removing ozone from a gas. According to this method, the gas is contacted with an adsorbent that includes a transition metal oxide or metal organic framework to form a treated gas. The treated gas is contacted with a noble metal catalyst to catalytically decompose ozone in the treated gas, thereby forming an ozone-depleted treated gas.

A vapor compression system () has: a centrifugal compressor () having an inlet () and an outlet (); and an electric motor () having a stator () and a rotor (). A plurality of bearings () support the rotor. A refrigerant charge comprises a base refrigerant and one or more oils. The one or more oils are present at a total concentration of 80-5000 parts per million (ppm) by weight.

Low-oil refrigerants and vapor compression systems

A heat transfer system is disclosed that includes a circulation loop of a heat transfer fluid that comprises a halocarbon. The circulation loop includes a compressor or pump that includes bearing rolling surfaces in contact with the heat transfer fluid. The bearing contact surface has a substrate a layer thereon that includes a polymer or oligomer having polar side groups and a tribofilm.

A cost-effective method of forming a hydrophobic coating on a substrate and coated substrates are disclosed. Specifically, the method comprises applying amorphous powders of an alloy to the substrate through a cold spray process. Also provided is a novel type of hydrophobic coating made of metallic glasses or amorphous alloys. The hydrophobic coatings offer advantages such as, low cost, low maintenance, and high corrosion resistance.

Corrosion resistant hydrophobic coatings and methods of production thereof
