Dr.-Ing. Klaus Löser studied Mechanical Engineering at TU Darmstadt, Germany. Then, a scientist in materials technology at TU Darmstadt with a focus on high-temperature materials. Since 1991, he has been with ALD Vacuum Technologies GmbH in Hanau, responsible for the heat treatment department. From 2021 until 2025, he was SVP R&D Heat Treatment and Metallurgy in ALD.
Water spray quenching achieves heat transfer coefficients up to 4,000 W/(m²K)—nearly double conventional oil quenching rates—enabling potential material substitution and tailored quench intensity for complex gear components.
