Christof Ziegler finished university in 1999 with a degree in process engineering. He worked for eight years at bifa GmbH in Augsburg and joined ALD Vacuum Technologies in 2007, where he worked in heat treatment for research and development, process optimization, and the worldwide commissioning of ALD heat treatment plants.
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.
