Emissionen von Bremsabnutzung, wie Bremsstaub und Feinstaub, geben der Automobilindustrie zunehmend Anlass zur Sorge und stellen angesichts immer strengerer und umweltpolitischer Vorschriften ein Problem dar.
Grauguss mit eingebettetem Graphit ist der gängigste Werkstoff, aus dem Bremsscheiben hergestellt werden. Grauguss-Bremsscheiben sind nicht nur günstig in der Herstellung, sie verfügen auch über alle notwendigen mechanischen Eigenschaften, die benötigt werden.
Da für KFZ-Bremsscheiben aus Kostensicht noch kein Werkstoff mit Grauguss konkurrieren kann, stellt die Beschichtung von Grauguss-Bremsscheiben eine praktikable und kostengünstige Lösung dar.
Herkömmliche thermische Beschichtungsverfahren sind jedoch noch sehr material- und kostenintensiv und die geforderten Eigenschaften hinsichtlich Schichthaftung, Korrosionsbeständigkeit und Rissverhalten können noch nicht erfüllt werden. Im Gegensatz zum Laserauftragschweißen gibt es für das Coldspray-Verfahren keinen Patentschutz eines großen Automobilherstellers.

Brake wear emissions, encompassing brake dust and particulate matter, have emerged as a mounting concern for the automotive industry in light of stricter environmental regulations set by the EU.
Brake discs predominantly originate from gray cast iron infused with embedded graphite. These gray cast iron brake discs not only offer cost-effective manufacturing but also encompass the essential mechanical attributes required.
While no other material currently matches the cost efficiency of gray cast iron for vehicle brake discs, coating such discs provides a practical and budget-friendly solution.
However, traditional thermal coating methods remain costly in terms of both materials and expenses, and they are unable to consistently meet the required criteria for coating adhesion, corrosion resistance, and resistance to cracking. In contrast, the cold spray process, unlike laser cladding, is unencumbered by patent restrictions from any major automotive manufacturer.
