A compression apparatus includes an outer shell; a first plate and second plate, where the first plate and the second plate are located within the outer shell and a face of the first plate opposes a face of the second plate The compression apparatus also includes a compression mechanism which retractably moves the face of the second plate into contact with the face of the first plate. The face of the first plate or the face of the second plate includes a substrate layer, and a coating layer over the substrate layer, where the coating layer includes a plasma-enhanced chemical vapor deposition material.

Compression apparatus and methods of making and using the same

According to an aspect of the present disclosure, a porous plate is provided. The porous plate includes a body having an upper surface, a lower surface opposite the upper surface and sidewalls extending between respective entireties of the upper surface and the lower surface, the body being formed of porous material, and a metallic coating, which is thermally deposited onto an entirety of the sidewalls to form a high-strength mechanical bond with the entirety of the sidewalls.

A disclosed method of hard coating a wear surface of a valve of an aircraft air management system is performed by depositing a hardface alloy powder onto the wear surface, heating the wear surface and the hardface alloy powder to transform the hardface alloy powder into a molten liquid mass, and subsequently cooling the molten liquid hardface alloy mass to solidify the hardface alloy onto the wear surface. The disclosed process provides for localized application and subsequent bonding of the hardface alloy to discrete portions of the wear surface. The solidified hardface alloy coating may then be machined to obtain specific wear surface geometries.

A thrust plate for a butterfly valve includes a thrust plate body that defines a recess. The recess extends between a bottom thrust surface, side walls and an open top. A wear-resistant coating is located on the bottom thrust surface.

Thrust plate for butterfly valve

A butterfly valve comprises a housing including a bore, a rotatable shaft passing through the bore, a disc mounted to the shaft for controlling the flow of a fluid through the bore, a thrust load reacting section and a wear interface. The thrust load reacting section includes a thrust plug assembled in a thrust reacting end of the shaft and a thrust plate secured to the housing. The thrust plate has a well for axially retaining the thrust plug and the thrust reacting end of the shaft. The wear interface includes a first contact region on the thrust plug with a first contact surface and a second contact region at the base of the well with a second contact surface. A portion of the first contact surface is spherical and in contact with a portion of the second contact surface.

Wear interface for butterfly valve

An article includes a titanium substrate, a metallic layer diffusion bonded with the titanium substrate and a residual stress region that extends through the metallic layer and at least partially into the titanium substrate.

Article for improved adhesion of fatigue-prone components

A method of processing an article includes mechanically working an article having a metallic layer disposed on a titanium substrate and establishing a residual stress region that extends through the metallic layer and at least partially into the titanium substrate.
