The invention relates to a steel component comprising a steel substrate having an anticorrosion coating present at least on one side of the steel substrate. This anticorrosion coating comprises a manganese-containing alloy layer. The manganese-containing alloy layer here forms the closest alloy layer of the anticorrosion coating to the surface. Moreover the manganese-containing alloy layer comprises iron and a further metal.

A manufacturing method is provided. During this method, a preform component is provided for a turbine engine. The preform component includes a substrate. A preform meter section and a preform diffuser section are formed in the substrate. An internal coating is applied to at least the preform meter section to provide a meter section of a cooling aperture. External coating material is applied over the substrate. The applying of the external coating material forms an external coating over the substrate. The applying of the external coating also builds up the external coating material within the preform diffuser section to form a diffuser section of the cooling aperture.

The object of the method is to obtain rolling mill rolls with a coating of tungsten carbide or of the alloys thereof, wherein the coating is a single layer and is carried out by means of high velocity thermal spraying.

In some embodiments, a coating applied to steel reinforcement bar (e.g., steel rebar) that could considerably extend the lifetime of concrete structures by reducing steel rebar corrosion is disclosed. The coating includes a thin, passivating steel (e.g., stainless steel) layer that is applied to the outside of conventional steel rebar. The coating can be applied in-line through metal cold spray manufacturing, which is a high throughput coating technique that can be integrated into existing steel manufacturing plants. Furthermore, a novel, high performance ferritic steel with tailored resistance to corrosion from chlorides is described. The new ferritic steel is distinct from other commercial and experimental steels, and is better suited for coating low-cost steel structures like rebar. Multiple alloying elements including Cr, Al, and Si will each form protective oxides independently, increasing the total amount of protection and extending it over much wider ranges of pH and electrical potential.

Provided are solar collection energy storage and energy conversion or chemical conversion systems. Also provided are tubing components, such as for solar receivers, including Mo and having a MoSiB coating on an external surface. The systems can include a solar receiver containing a heat transfer material or chemically reacting material and can operate at temperatures of 700° C. or higher. The solar receiver can include tubing components selected from a Mo tubing component, a MAX phase material tubing component, a MoSiB composite tubing component, or a combination thereof. The Mo component, when present, can include a coating on surfaces of the Mo component that operate above 700° C.

An abradable powder composition is includes a metal component, a lubricant component, and a polymer component. A portion of the metal component is wrapped in the lubricant component to achieve high lubricity and abradability. The abradable powder composition can be used to form an abradable seal coating provided for use in a turbo machinery having a housing and a wheel having multiple blades. The housing houses the wheel which rotates therein. The seal coating is formed on the inner walls of housing adjacent where the wheel blades pass during their rotation. When the wheel is rotated such that, the blades contact the seal coating, it is abraded to form a close fit gap. The abradable seal coating preferably does not produce significant wear of the blade tips or transfer abradable material significantly to the blade tips upon being abraded.
