Journal ArticleDOI
Optimization and Characterization of High Velocity Oxy-fuel Sprayed Coatings: Techniques, Materials, and Applications
TL;DR: In this article, the main differences in spray conditions in terms of particle kinetics and thermal energy are rationalized and methods and tools for controlling the spray process are presented as well as their use in optimizing the coating process.
Journal ArticleDOI
Parameter optimization of HVOF sprayed nanostructured alumina and alumina-nickel composite coatings
Erja Turunen,Tommi Varis,Tom E. Gustafsson,Jari Keskinen,Teppo Fält,Simo-Pekka Hannula,Simo-Pekka Hannula +6 more
TL;DR: In this paper, a high velocity oxy-fuel (HVOF) spraying of nanocrystalline Al 2 O 3 -Ni-coating has been described, where up to ten percent of nickel has been added in order to toughen the coating and the resulting microstructure of the coatings and effect of it on the coating properties is discussed.
Journal ArticleDOI
On the role of particle state and deposition procedure on mechanical, tribological and dielectric response of high velocity oxy-fuel sprayed alumina coatings
Erja Turunen,Tommi Varis,Simo-Pekka Hannula,A. Vaidya,Anand A. Kulkarni,J. Gutleber,Sanjay Sampath,Herbert Herman +7 more
TL;DR: In this paper, an integrated approach to establish processing-microstructure-property correlations in order to optimize coatings for high velocity oxy-fuel (HVOF) sprayed alumina coatings is presented.
Journal ArticleDOI
Residual stresses in HVOF-sprayed ceramic coatings
Giovanni Bolelli,Luca Lusvarghi,Tommi Varis,Erja Turunen,Matteo Leoni,Paolo Scardi,Cristy Leanor Azanza-Ricardo,Massimilano Barletta +7 more
TL;DR: In this paper, the residual stress state of thermally sprayed ceramic coatings was examined by combining different experimental and analytical techniques, in order to provide a thorough characterisation of through-thickness stress profiles and a cross-verification of results.
Journal ArticleDOI
Behavior of HVOF WC-10Co4Cr Coatings with Different Carbide Size in Fine and Coarse Particle Abrasion
Arash Ghabchi,Arash Ghabchi,Tommi Varis,Erja Turunen,Tomi Suhonen,Xuwen Liu,Simo-Pekka Hannula +6 more
TL;DR: In this paper, a modified ASTM G 65 rubber wheel test was employed in wet and dry conditions using 220nm titania particles and 368μm sand particles, respectively, and it was shown that the wear mechanism depends on the relative size of the carbide and abrasive particles.
