Diffusion Barriers Minimizing the Strength Degradation of Reactive Air Brazed Ba0.5Sr0.5Co0.8Fe0.2O3-δ Membranes during Aging

The separation of oxygen from air by means of inorganic ceramic membranes requires gas-tight ceramic–metal joints that enable reliable permeation operation in the oxygen partial pressure gradient at 850 °C. Reactive air brazing is a promising method to solve this challenge. However, reactive air brazed BSCF membranes suffer from a significant strength degradation that is caused by unhindered diffusion from the metal component during aging. In this study, we investigated how diffusion layers applied on the austenitic steel AISI 314 influence the bending strength of BSCF-Ag3CuO-AISI314 joints after aging. Three different approaches were compared as diffusion barriers: (1) aluminizing via pack cementation, (2) spray coating with NiCoCrAlReY, and (3) spray coating with NiCoCrAlReY and an additional 7YSZ top layer. Coated steel components were brazed to bending bars and aged for 1000 h at 850 °C in air prior to four-point bending and subsequent macroscopic as well microscopic analyses. In particular, coating with NiCoCrAlReY showed low-defect microstructures. The characteristic joint strength was raised from 17 MPa to 35 MPa after 1000 h aging at 850 °C. In addition, the dominant delamination fracture between the steel and the mixed oxide layer, observed in the reference series with uncoated steel, could be replaced by mixed and ceramic fractures of higher strength. The effect of residual joint stresses on the crack formation and path is analyzed and discussed. Chromium poisoning could no longer be detected in the BSCF, and interdiffusion through the braze was effectively reduced. Since the strength degradation of reactive air brazed joints is mainly caused by the metallic joining partner, the findings on the effect of the diffusion barriers in BSCF joints might be transferred to numerous other joining systems.

Die Nichtinanspruchnahme von Grundsicherung als Bewältigungsstrategie

Der Weite Weg Zum Bürgergeld

View full text Add to dashboard Cite

ZusammenfassungGrundsicherungsleistungen sollen ein menschenwürdiges Existenzminimum sicherstellen und gesellschaftliche Teilhabe ermöglichen. Doch viele Anspruchsberechtigte verzichten auf ihre Leistungen. Der Beitrag untersucht das Phänomen der Nichtinanspruchnahme von Grundsicherungsleistungen und fragt nach den Implikationen der Bürgergeld-Reform. Mithilfe eines qualitativen Studiendesigns wird die Perspektive der Verzichtenden rekonstruiert und aufgezeigt, dass es verschiedene Strategien gibt, um ohne Grundsicherungsleistungen den Alltag zu bewältigen. Das Ziel ist es, die subjektiven Deutungen und alltagsweltlichen Logiken hinter der Nichtinanspruchnahme von Grundsicherungsleistungen zu verstehen. Aus den im Jahr 2022 geführten episodischen Interviews im Raum Thüringen wurden vier Idealtypen der Nichtinanspruchnahme entwickelt. Im Ergebnis lässt sich die Nichtinanspruchnahme als Möglichkeit der Bewahrung von Vorläufigkeit, der Abkehr von Normalitätsvorstellungen im Zusammenhang mit Autonomiebestrebungen, der Entlastung von bürokratischen Hürden und der Abgrenzung von einem stigmatisierendem System rekonstruieren. Die subjektzentrierte Perspektive lässt vermuten, dass die Neuerungen des Bürgergeldes nur wenig am Inanspruchnahmeverhalten ändern.
