Brake disc coating:

The adoption of EU Regulation 2024/157, commonly referred to as the Euro 7 standard, increases the requirements for new car models in many respects. The core objective of the regulation is to reduce exhaust gases and particulate matter emissions.

For the first time, particulate emissions caused by tyre and brake wear are also included and regulated.

With regard to cast-iron brake discs, the aim was to make the surface of these components more wear-resistant. This increase in wear resistance is to be achieved by coating with suitable metal powders and carbides.

As a supplier of customised metal powders, Steel Service Krefeld GmbH is a partner in several development projects. Stainless steel powders such as 430L, 318LN, manganese steel powders such as 1.3820 and carbides in various designs are already being supplied.

ECO-HARD.ONE:

ECO-Hard.ONE is a mixture of two alloyed metal powders that is used for coating brake discs. The primary application purpose is wear protection.

The purpose of coating with ECO.Hard.ONE is to reduce the fine dust emissions that are produced during a conventional braking process. The application of this metal powder mixture to a standard, cast-iron brake disc results in increased hardness, wear resistance and corrosion resistance with minimally reduced thermal conductivity. This optimisation of properties results in a longer life cycle for the brake disc and the brake pad without compromising braking performance.

In contrast to other competitor technologies for brake disc wear protection, ECO-Hard.One does not use any external carbides.
