Method for Combined Edge Layer Treatment of Components Made from Lightweight Construction Materials
Simple SummaryContent extracted from patent full text and abstract with AI.
This invention describes a process for combined surface layer treatment of lightweight components, especially those made from materials like aluminum alloys. The method involves melting and alloying the surface layer of the component using an energy beam and adding alloying elements to bond with the base material. The surface is kept molten until the additives are fully dissolved or dispersed, then cooled to form a fine-grained solid layer. Afterward, a hard coating is applied using a physical vapor deposition (PVD) process.
Use CasesContent extracted from patent full text and abstract with AI.
- Improving wear resistance and lifespan of lightweight automotive or aerospace parts
- Enhancing corrosion resistance of aluminum alloy machine components
- Extending durability of lightweight structures in transportation or consumer electronics
- Optimizing performance of lightweight mechanical parts in industrial equipment
BenefitsContent extracted from patent full text and abstract with AI.
- Significantly enhances the surface properties (like hardness and resistance) of lightweight materials without adding excessive weight
- Combines metallurgical bonding with hard coating for superior durability compared to conventional coatings alone
- Enables use of lightweight metals such as aluminum in demanding applications by improving their surface robustness
- Potentially reduces component wear, maintenance needs, and operational costs

Patent Abstract
Die Erfindung betrifft ein Verfahren zur kombinierten Randschichtbehandlung von Bauteilen aus Leichtbauwerkstoffen, wie Aluminiumlegierungen, mit folgenden Verfahrensschritten: Randschicht-Umschmelzlegieren unter Aufschmelzen einer Randschicht des Bauteiles durch einen Energiestrahl in Verbindung mit Zusatzstoffen zu deren metallurgischer Verbindung mit dem Basismaterial, Aufrechterhalten einer flüssigen Phase in der Randschicht bis die Zusatzwerkstoffe zumindest teilweise in der flüssigen Phase in Lösung gegangen oder in dieser dispergiert sind, Abkühlen der Randschicht und Umwandlung der flüssigen Phase in einen feinkörnigen feindendritischen, festen Zustand und anschließende Hartstoffbeschichtung des mit einer umschmelzlegierten Randschicht versehenen Matrixmateriales mittels PVD-Verfahren und ein entsprechendes Bauteil aus Leichtbauwerkstoffen.
