The integrity, and especially, the cohesive strength of alumina plasma-sprayed coatings
prepared from a range of precursor powders of different size and crystallinity has been …

Plasma-sprayed alumina coatings are widely used as wear resistant coatings on a variety of
metallic substrates. However, the particular structures of plasma-sprayed coatings (lamellar …

The mechanical properties of a series of plasma sprayed ceramic coatings made from
alumina, chromia and alumina–titania precursor powders have been evaluated in particle …

Plasma-sprayed coatings are built up from individual overlapping solidified droplets, and the
nature of boundaries between these “splats” influences their mechanical and wear …

A series of plasma sprayed alumina coatings was evaluated regarding their erosion and
abrasion characteristics. The coatings were deposited under different spraying conditions …

A set of plasma sprayed coatings were obtained from three alumina based top coat and two
bond coat powders. Scratch test was undertaken on these coatings, under constant and …

The objective of this study is to compare the tribological properties of alumina coatings with
two different structural scales, a micrometer-sized one manufactured by atmospheric plasma …

The paper concerns the use of traditional and depth-sensing indentation (DSI) for
investigation of deposits produced from powders based on conventional and nano-sized …

A test method has been developed which allows the determination of the shear stress
necessary to cause adhesive or cohesive failure of plasma-sprayed coatings. The shear …

This paper discusses the influence of 40 wt% TiO 2 addition to Al 2 O 3 and the selection of
plasma spray parameters on the morphology, microstructure, microhardness and adhesion …
