Abstract: Clamping device including sheet metal, wedge-washers, and fastening members. Sheet metal includes first segments and second segment, where each of the first and second segments include conduit-facing end and outwardly-extending end. Conduit-facing ends are joined to each other and wrapped around conduit in opposite directions. Outwardly-extending ends extend in opposite direction to outwardly-extending end. Each outwardly-extending end is bent at bend angle towards a respective conduit-facing end. Wedge-washers are disposed on first and second segments. Each wedge-washer includes sidewall inclined in a direction opposite to bend angle and in contact with a respective outwardly-extending end. Fastening members are disposed on respective wedge-washer.

Abstract: A system and method are disclosed. The system includes an assembly with a base, and a coating disposed on the base, wherein the coating has a density greater than 98 percent of a theoretical density of the coating, and a dilution less than 0.5 volume percent of the coating. In an embodiment, the assembly includes a shaft and a journal bearing coupled to the shaft, wherein at least one of the shaft and the journal bearing includes the base. In another embodiment, the assembly includes a valve coupled to a valve seat, wherein at least one of the valve and the valve seat includes the base, and the base includes a plurality of dimples, the coating disposed on at least some dimples. The method is for disposing a coating on a base of the assembly using a friction surface process.

Abstract: In accordance with one embodiment, a system is presented. The system includes a casing, a combustor disposed within the casing, and a sensing device located on the casing and configured to sense a plurality of acoustic emission waves and generate an electrical signal based on the sensed plurality of acoustic emission waves. The system further includes a processing subsystem operationally coupled to the sensing device and configured to determine one or more features based on the electrical signal, and determine a presence or an absence of fretting wear in the combustor based at least on the one or more features.
