Brake disc coating:

With the adoption of EU Regulation 2024/157, colloquially referred to as the Euro 7 standard, the requirements for new car models are increasing in many respects. The core objective of the regulation is to reduce exhaust gases and particulate emissions. For the first time, particulate emissions from tire and brake wear are also being taken into account and regulated.

With regard to cast iron brake discs, work has therefore been carried out to make the surface of these components more wear-resistant. This increase in wear resistance is to be achieved by coating them with suitable metal powders and carbides.

As a supplier of metal powders manufactured to customer requirements, 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 today.

ECOHARD.One:

ECOHARD.ONE is a mixture of two alloyed metal powders used in the coating of brake discs. Its primary purpose is wear protection. The ECOHARD.ONE coating serves to reduce

fine dust emissions generated during conventional braking. Applying this metal powder mixture to a standard cast iron brake disc results in greater hardness, wear resistance, and corrosion resistance with minimally reduced thermal conductivity. This optimization of properties results in a longer life cycle for the brake disc and brake pad without compromising braking performance.

Unlike other competing technologies for wear protection of brake discs, ECOHARD.ONE does not use any external carbides.
