Wire and Arc Additive Manufacturing of Manganese Aluminium Bronze: Microstructure control for corrosion resistance

Wire and Arc based Additive Manufacturing (WAAM) processes are novel technologies that are seen as promising candidates for fabricating complex 3-Dimensional large scale components. These processes offer avenues to locally tailor metallurgy of the melt pool and thus produce functionally and compositionally graded components for improved...

Artefact biography 2.0: the information value of corroded archaeological bronzes

The different phases in the life of archaeological objects can be described by artefact biography. This dissertation defines an updated version: artefact biography 2.0, and the life phases of Early Iron Age bronze studs from Oss-Zevenbergen, the Netherlands, are elaborated. Throughout the thesis, the research revolves around information value....

Curly malachite on archaeological bronze: A systematic study of the shape and phenomenological approach of its formation mechanism

Curly malachite (CM) is found as a green cupric carbonate hydroxide corrosion product on archaeological bronze, mostly on artefacts retrieved from graves. In this paper, a morphological characterization approach is proposed, enabling the investigation of the formation process of CM. It is suggested that curly malachite precipitates from an...
