Solid State Reactions in Al-Ni Composites Made by Mechanofusion

Abstract

means of different methods: electron probe microanalysis (EPMA), transmission electron microscopy (TEM), electron diffraction (ED), energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD). The presence of the intermetallic phases confirmed that phase forming solid state reactions start during the mechanofusion treatment.

The Influence of Dry Particle Coating Parameters on Thermal Coatings Properties

“…Consequently, deposits are built with a homogeneous distribution of phases and the appearance of intermetallic phases formed during spraying (Ito et al, 1991;Kim, 1997;. Several authors have evaluated different configurations of powdered systems for plasma spraying including: NiAl/TiC/ZrO 2 (Herman et al, 1992a;Herman et al, 1992b), AlCuFe and AlCuCo (Csanády, 1997), NiAl or NiCrAl-TiC-ZrO 2 (Bernard, 1994), and 316L stainless steel -α-Al 2 O 3 (Ageorges & Fauchais, 2000;Cuenca-Alvarez et al, 2003a, 2003b.…”

Mechanofusion Processing of Metal-Oxide Composite Powders for Plasma Spraying

“…Similar results are found when resin particles are coated by a carbon film [5]. The powder system is chosen by considering a review of the bibliography oriented towards a wear resistance application [9][10][11][12][13][14][15]. Some fuel cells components are prepared by the MF process for instance based on nickel-cobalt oxide helping to decrease nickel dissolution when melting of carbonate occurs [8].…”

Nanoanalyse der Frühstadien der Interreaktion im System Al/Ni mittels 3D-Atomsondentomographie

“…Gleichgewichtsphasen von der Al reichen Seite, unter Auslassung der Phase Al 3 N i 5 , hin zu Phasen höheren Ni Gehaltes an[30,8,31,32,11]. Diese Sequenz stimmt mit der Sequenz überein, die nach dem Modell von Pretorius vorhergesagt worden ist (vgl.…”
