Higher in-flight particle velocities enhance in vitro tribological behavior of plasma sprayed hydroxyapatite coatings
Khun, Nay Win; Li, Zhong Alan; Khor, Khiam Aik; Čížek, Jan (Elsevier, 2016-11-01)Hydroxyapatite (HA) coatings were deposited onto Ti6Al4V substrates via atmospheric plasma spraying under systematically varying spray parameters, leading to different in-flight particle velocities. Morphology, composition, ... -
In-Flight Temperature And Velocity of Powder Particles of Plasma Sprayed TiO2
Čížek, Jan; Khor, Khiam Aik; Dlouhý, Ivo (Springer, 2013-10-25)This paper relates to the in-flight temperature and velocity of TiO2 particles, an integral part of the systematic research on atmospheric plasma spraying of the material. Initial powder feedstock (32-45 um, 100% rutile ... -
Influence of Cold-Sprayed, Warm-Sprayed and Plasma Sprayed Layers Deposition on Fatigue Properties of Steel Specimens
Čížek, Jan; Matějková, Michaela; Dlouhý, Ivo; Šiška, Filip; Kay, Charles; Karthikeyan, Jeganathan; Kuroda, Seiji; Kovářík, Ondřej; Siegl, Jan; Loke, Kelvin; Khor, Khiam Aik (Springer, 2015-03-10)Titanium powder was deposited onto steel specimens using four thermal spray technologies: plasma spray, low-pressure cold spray, portable cold spray, and warm spray. The specimens were then subjected to strain controlled ... -
Influence of plasma and cold spray deposited Ti Layers on high-cycle fatigue properties of Ti6Al4V substrates
Čížek, Jan; Kovářík, Ondřej; Siegl, Jan; Khor, Khiam Aik; Dlouhý, Ivo (Elsevier, 2013-02-25)This paper presents a summary of the research on the influence of plasma and cold spray deposition of bio-grade Ti powder on the high-cycle fatigue properties of Ti6Al4V substrates. Four sets of flat specimens (as-received, ... -
Modification of Plasma Sprayed TiO2 Coatings Characteristics via Controlling the In-flight Temperature and Velocity of the Powder Particles
Čížek, Jan; Dlouhý, Ivo; Šiška, Filip; Khor, Khiam Aik (Springer, 2014-08-27)The study presents a comprehensive research on the plasma spray fabrication of TiO2 coatings with microstructural properties adjustable via controlling the respective in-flight properties of the feedstock particles. The ... -
Role of In-flight Temperature and Velocity of Powder Particles on Plasma Sprayed Hydroxyapatite Coating Characteristics
Čížek, Jan; Khor, Khiam Aik (Elsevier, 2012-01-15)This paper presents a systematic research on the process of thermal spraying of HA encompassing all stages of layer deposition: powder production and characterization (optimized production led to spherical 29.29 - 50.51 ...
