20190194799 · 2019-06-27 ·

An embodiment of a line-of-sight coating fixture includes a support structure, a spindle, and a shadow structure. The support structure includes a plurality of compartments disposed below a platter, each compartment having an opening on a periphery of the support structure. Each compartment is adapted to receive and secure a base of a workpiece such that a body of each workpiece to be coated is disposed about a periphery of the support structure and extends above the platter. The spindle is disposed through a center of the platter or support structure for rotating the workpieces thereabout. The shadow structure is disposed about the spindle, inside of the periphery, the shadow structure sized and adapted to shield a portion of each workpiece from line-of-sight coating material.

Metal sheet and method for its treatment

A method for treating sheet metal is disclosed in which a material containing at least one alloying element is applied onto a first area of at least one surface of the metal sheet. A second area of the surface is kept free of the material. The metal sheet is subsequently heat treated in order to diffuse the alloying element into the first area of the metal sheet. The temperature of the first area is lower than the melting temperature of the metal sheet during the diffusion.

Multi-layer feature fill

Described herein are methods and apparatuses for filling semiconductor substrate structures with conductive material. The methods involve depositing multi-layer bulk metal films in structures with one or more deposition conditions changed when transitioning from layer-to-layer. The methods result in high fill quality, high throughput, low precursor consumption, and low roughness. Multi-station chambers to perform the methods are also provided.

METHOD FOR COATING A COMPONENT FOR THE HOT GAS DUCT OF A TURBOMACHINE

The invention relates to a method for coating a component, which is provided for the hot gas duct of a turbomachine, wherein the coating material is applied onto the uncoated component surface in the form of particles in mixture with a binding agent, and the component with the particle-treated binding agent thereupon then undergoes thermal treatment in such a way that the binding agent is released and the coating material remains on the component.

Methods of applying chromium diffusion coatings onto selective regions of a component

Unique and improved chromizing processes are disclosed. The processes involve forming localized chromizing coatings onto selected regions of a substrate. The chromium diffusion coatings are locally applied to selected regions of substrates in a controlled manner, in comparison to conventional chromizing processes, and further in a manner that produces less material waste and does not require diffusion-stop-off masking. Prior to or after a localized slurry chromizing process of the present invention, a layer of a platinum-group-metal (PGM) is applied to produce a PGM-modified chromium diffusion coating onto selected regions of a substrate. A second coating can be selectively applied onto other regions of the substrate.

Maskant for use in aluminizing a turbine component

A mask is used in aluminizing of superalloy turbine component, such as a turbine blade, where a region exposed to relatively high operating temperature is aluminized to form a diffusion aluminide coating and another region exposed to relatively lower operating temperatures is masked to prevent aluminizing of the masked region while concurrently being enriched in Cr and/or retaining a pre-existing Cr-content from the superalloy chemistry itself or from a previous chromizing operation.
