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.

This article intends to summarize our actual knowledge in plasma spraying with an emphasis on the points where work is still in progress. It presents successively: the plasma torches with the resulting plasma jets and their interactions with the surrounding environment; the powder injection with the heat, momentum and mass transfers between particles ...

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.

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.

In this volume it should be unnecessary to extol the virtues of beryllium. The aim is to show that the plasma-spray method of consolidating beryllium powder, usually followed by a densifying heat treatment, can produce high-strength material competitive in properties and cost with that made by any other route.

Plasma Spraying of Spray-Dried AI2O3 Powders
International Thermal Spray Conference, 2000Abstract Today, powder particles diameter used for thermal spraying is generally comprised between 5 and 100µm with a preferred range around 40µm for APS applications. Actually, the future trends in plasma spraying are directed to the use of fine or ultrafine powders and the reduction of the steps between raw materials and coatings.
