The present invention concerns the field of vehicle technology and industrial-plant technology and relates to a brake disc provided with protection from wear and corrosion and to a method for production thereof. The known solutions have the disadvantage that the coating for providing protection from corrosion and wear is applied to the frictional surfaces of the brake disc and is rubbed off straight away during the first braking operations. The present invention addresses the problem of providing a brake disc that has improved and durable protection from corrosion and wear. The significantly improved properties of the brake disc in terms of protection from corrosion and wear are achieved according to the invention by at least the region of the frictional surfaces (2) having an AlSi-based diffusion layer (3), which has a layer thickness of 0.1 mm to 0.6 mm and is formed in the process of interaction with the steel or grey cast iron of the metal main body (1). The brake disc according to the invention can be used for example in vehicles or as a braking system for industrial brakes or in wind turbines.

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.
