A gas turbine component for use in a gas turbine engine includes a substrate a ceramic-based thermal barrier coating (TBC), and a diffusion chromide bond coat between the base material and the TBC. A thermally grown oxide (TGO) layer can be formed on the bond coat prior to application of the TBC. The TBC and the TGO include a common metal oxide. The oxide can be sacrificially in use and soluble in a molten sulfate salt, make the coating system particularly suitable for use in a marine environment.

Disclosed is a novel moisture permeation barrier system for substrates and devices and method of making the same. The permeation barrier system includes two barrier layers. The first barrier layer is disposed over the substrate or an electronic device. The second barrier layer is then disposed over the first barrier layer. This system has relatively low permeability to moisture and is flexible. It may cover particles and provide moisture protection with a relatively small width edge seal.

摘要:
A bearing for an internal combustion engine may include a ferrous base material onto which a primary layer of a bronze alloy is disposed and a deposited layer applied over the primary layer. A bonding layer may be applied onto the primary layer between the primary layer and the deposited layer. The bonding layer may include nickel and chrome, and the deposited layer may include a metal alloy composed of aluminum and tin. A sliding layer may be disposed on the deposited layer and include a polymeric polyamide-imide matrix provided with a soft metal and at least one of a fluoropolymer and a silane-based material. The ferrous base material, the primary layer, the bonding layer, the deposited layer and the sliding layer in combination may be capable of standing a gripping load higher than 85 MPa.
摘要:
To apply a thermal barrier coating (10), a plasma jet (5) is generated by a plasma torch in a work chamber (2) and is directed to the surface of a substrate (3) introduced into the work chamber, and a ceramic coating material is applied to the substrate surface by means of PS-PVD, wherein the coating material is injected into the plasma jet as a powder and is partly or completely vaporized there. On applying the thermal barrier coating, in a first workstep the feed rate of the injected powder is set so that a large part of the injected powder vaporizes, wherein the coating material condenses from the vapor phase on the substrate surface and forms mixed phases with the material of the substrate surface. In a second workstep, the feed rate of the injected powder it increased by at least a factor of 5, whereby the portion of the powder which vaporizes is reduced and the coating material is deposited in the form of elongate columns which form an anisotropic microstructure and which are aligned substantially perpendicular to the substrate surface.
