A control system and method utilizing one or more processors that are configured to determine contaminant loading of blades of a turbomachinery compressor based on one or more environmental conditions to which the turbomachinery compressor is exposed and one or more atmospheric air inlet conditions of the turbomachinery compressor. The one or more processors then determine a corrosion contaminant concentration on the blades of the turbomachinery compressor based on the contaminant loading that is determined and determine an upper limit on or a distribution of potential corrosion of the blades of the turbomachinery based on the corrosion contaminant concentration, at least one of the environmental conditions to which the turbomachinery compressor is exposed, and the corrosion contaminant concentration that is determined.

Methods for repairing flange bolt holes and the resulting flange bolt holes are provided. The methods and products include the incorporation of a coating system comprising a corrosion resistant layer, which can be formed by resistance plug welding, slurry or sol-gel processing, or thermal/cold spray processing. The corrosion resistant layer can be a super alloy or ceramic material and is different than the base material of the flange bolt hole. Corrosion of the flange bolt hole can be reduced or prevented from occurring with the use of the coating system.

A compressor blade for use in a compressor section of a gas turbine engine, comprising: a martensitic stainless steel compressor blade and an abrasive coating having an anodic component. The compressor blade has a blade portion, a dovetail portion and a platform portion intermediate the blade portion and the dovetail portion, the blade portion terminating in a tip opposite the dovetail portion. A cobalt-based coating overlies at least the blade portion of the compressor blade. The cobalt-based coating comprises a cobalt based material that includes precipitates of tungsten carbide that provide erosion resistance and particles of a sacrificial metal-based material distributed through the cobalt-based coating that provide galvanic corrosion resistance to the system.

The present disclosure relates to methods for manufacturing porous mesh plates for use in ultrasonic mesh nebulizers, and the porous mesh plates manufactured by those methods. Cone-shaped dimples are first drilled in a substrate (e.g. a plate), but do not penetrate the bottom of the substrate. Next, the substrate (e.g. a plate) is subject to an electrochemical process to remove a layer of material from the surface of the substrate. Enough material is removed to allow the dimples to penetrate the substrate, thereby creating holes in the substrate. The size of the holes can be controlled by the conditions of the electrochemical process.

A composition is provided that includes a ternary electrolyte having a melting point greater than about 150 degree Celsius. The ternary electrolyte includes an alkali metal halide, an aluminum halide and a zinc halide. The amount of the zinc halide present in the ternary electrolyte is greater than about 20 mole percent relative to an amount of the aluminum halide. An energy storage device including the composition is provided. A system and a method are also provided.

Energy storage device and method

An article of electrochemical energy conversion is provided that includes a separator. The separator has a first surface that defines at least a portion of a first chamber, and a second surface that defines a second chamber, and the first chamber is in ionic communication with the second chamber through the separator. The energy storage device further includes a plurality of cathodic materials. The plurality includes at least a first cathodic material and a second cathodic material. Both of the cathodic materials are in electrical communication with the separator and both are capable of forming a metal halide. A proviso is that if either of the first cathodic material or the second cathodic material is a transition metal, then the other cathodic material is not iron, arsenic, or tin.
