The present paper refutes this common perception by examining the structural changes in MCrAlY as induced by cold spraying (CS). The cold-sprayed coatings were characterized for phase composition and microstructural features using X-ray diffraction, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) techniques. These results are compared with those obtained from the feedstock powder, as well as those obtained from ball-milled powder. An extensive phase transition from bcc to fcc is observed after both CS and after ball milling. In CS, in addition, there is evidence for substantial grain refinement, which is not observed after ball milling."],["dc.identifier.doi","10.1002/adem.201400174"],["dc.identifier.isi","000354417300019"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37231"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.relation.issn","1527-2648"],["dc.relation.issn","1438-1656"],["dc.relation.orgunit","Institut für Materialphysik"],["dc.title","Strain-Induced Phase Transformation of MCrAlY"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Cold spraying is a well-established method for metal on metal coatings. In cold spraying, the required heat for bonding is provided by plastic deformation of the impacting ductile particles. In contrast, few authors have investigated the impact phenomena and layer formation process for spraying brittle ceramic materials on ductile metal surfaces. In this study, the formation of TiO2 coatings on aluminum, copper, titanium, and steel substrates was investigated by SEM, TEM, XRD, and Raman spectroscopy. The results show that the deposition efficiency depends on spray temperature, powder properties, and in particular on substrate ductility, even for impact of ceramic particles during a second pass over already coated areas. Ceramic particles bond to metallic substrates showing evidence of shear instabilities.

In the shock front the powder is deformed under high strain rates, which under suitable conditions results in high-strength bonding of the particles. Thus, the microstructural features obtained by both techniques should be similar.
