David Allen

Emeritus Professor of Micro Engineering

Cranfield University

Abstract

A superalloy is a metal specifically designed for applications requiring a high level of resistance to elevated temperatures, high tensile strength, and resistance to corrosion. Superalloys are therefore often used in chemical conversion plants, industrial and aerospace turbines, medical implants and devices containing precision springs and diaphragms.

These materials are extremely difficult to machine by conventional cutting methods as the materials work-harden when being machined. Fabrication by chemical machining is therefore a preferred technique. However, as these materials are also corrosion-resistant, they can also be difficult to etch.

This presentation reviews how a wide range of nickel-based and cobalt-based superalloys can be etched by aggressive chemical etchants or electrolytic photoetching techniques with reduced health, safety and environmental impacts.

Abstract

This presentation will highlight the advancements in direct imaging, coming a long way from its “standard” resolutions down to single-digit figures, focusing on the developments in the light source and imaging technology itself, but also the interdependencies between equipment capabilities and existing processes aimed to evolve towards generating finer structures and features.

Miniaturization as a determined goal does not only address higher resolution but also higher accuracy requirements.

The importance of highly accurate front-to-back alignment, especially for metal etching applications, along with increased complexity due to higher demand for automation and traceability functions, will be answered in this presentation showcasing intelligent solutions to today’s equipment and the approach of diverse challenges from an application’s / process perspective.

As the host of this year’s Facility Tour, a short introduction to what visitors can expect from the visit at Schmoll Maschinen will be given.
