Evaluation of titanium plasma-sprayed and plasma-sprayed hydroxyapatite implants in vivo
Biomaterials, 2004In this study, bone interfacial strength and bone contact length at the plasma-sprayed hydroxyapatite (HA) and titanium plasma-sprayed (TPS) implants were evaluated in vivo. Non-coated titanium (Ti) implants were used as controls. Cylindrical coated or non-coated implants (4.0mm diameter by 8mm long) were implanted in the dogs' mandibles.

Plasma sprayed coatings of hydroxylapatite
Journal of Biomedical Materials Research, 1987AbstractThe technique of plasma spraying has been applied to deposite a thin, dense layer of hydroxylapatite onto a titanium substrate. Bond strength of such apatite coatings with the substrate have been measured, as well as the (absence of) influence of the coating process on fatigue properties of the substrate.

Comparison of plasma-sprayed alumina coatings by RF and DC plasma spraying
Journal of Thermal Spray Technology, 1995Splat size and shape- factor distributions for plasma- sprayed alumina particles on various substrates were studied using a setup derived from the line- scan test. Direct- current (dc) and radiofrequency (rf) plasma torches were used to study the influence of particle velocity at impact. The influence of substrate temperature prior to spraying also was

Zircon, ZrSiO4, is a natural mineral used for various applications as a refractory bulk material. It is an excellent feedstock for the plasma spraying of protective coatings and free-standing bodies. Zircon decomposes on spraying into t-ZrO2 and glassy SiO2, which can be preserved in deposits by fast cooling.

Spraying of MgO films with a well-controlled plasma jet [PDF]
Surface and Coatings Technology, 2003 With the use of our original thermal plasma reactor, spraying of MgO films was studied. Under some experimental conditions, MgO films were well prepared, although spraying of MgO is usually said to be difficult due to its particular properties.

Plasma-sprayed zirconia electrolytes
Solid State Ionics, 1988Yttria stabilized zirconia is widely used as an electrolyte in electrochemical devices such as high temperature solid oxide fuel cells (HTSOFC) (1) and oxygen sensors (2). In order to reduce the ohmic resistance it is interesting to obtain electrolyte layers as thin as possible.
