Amorphous Steel Coating for Concrete Delivery Wear

The patent applies composite materials by combining a lightweight substrate (aluminum, magnesium, or steel alloy) with a hard wear-resistant coating (metallic glass or ceramic). This composite structure allows the component to benefit from the low weight of the substrate while the coating provides the necessary wear resistance, thus resolving the contradiction between weight reduction and wear life extension.

The patent changes the physical and chemical parameters of the surface layer by applying a coating with different material properties than the substrate. The coating layer has high hardness and wear resistance parameters, while the substrate maintains low density. This parameter differentiation allows the component to achieve both light weight and long wear life.

Instead of using plain carbon steel throughout the entire component, the patent uses a composite structure where a lightweight substrate is combined with a hard coating. This allows wear resistance to be achieved at the surface level without compromising the overall weight of the component, as the lightweight substrate provides sufficient structural support when combined with the protective coating.

The patent applies local quality by providing different material properties at different locations within the component structure. The substrate provides lightweight structural support while the surface coating provides localized wear resistance. This spatial differentiation of material properties allows the component to achieve both low weight and high wear resistance without requiring the entire component to be made of heavy steel.

The patent uses a composite material system where the coating layer (metallic glass or ceramic) provides non-stick properties that prevent concrete residue buildup. While the manufacturing process becomes slightly more complex due to the coating step, the coating is applied using established thermal spray or deposition techniques, maintaining reasonable manufacturing simplicity while effectively eliminating the harmful residue buildup issue.

The patent converts the potential harm of concrete residue buildup into a benefit by using a coating material that actively prevents adhesion. The coating transforms the surface properties from concrete-adhesive (harmful) to concrete-release (beneficial), eliminating maintenance downtime and preserving payload capacity without significantly complicating the manufacturing process.
