“…The hightemperature enables the use of coating materials with a high melting point such as ceramics, cermets, and refractory materials. Materials can be processed as long as there is a temperature difference of at least 300 K between the melting temperature and decomposition or evaporation temperature [53].…”

Plasma-surface modification (PSM) is an effective and economical surface treatment technique for many materials and of growing interests in biomedical engineering. This article reviews the various common plasma techniques and experimental methods as applied to biomedical materials research, such as plasma sputtering and etching, plasma implantation, plasma deposition, plasma polymerization, laser plasma deposition, plasma spraying, and so on. The unique advantage of plasma modification is that the surface properties and biocompatibility can be enhanced selectively while the bulk attributes of the materials remain unchanged. Existing materials can, thus, be used and needs for new classes of materials may be obviated thereby shortening the time to develop novel and better biomedical devices. Recent work has spurred a number of very interesting applications in the biomedical field. This review article concentrates upon the current status of these techniques, new applications, and achievements pertaining to biomedical materials research. Examples described include hard tissue replacements, blood contacting prostheses, ophthalmic devices, and other products. #

“…Particles land on the substrate where they spread and solidify forming a coating layer. [15] TBCs are essential for increasing the operation temperature in gas turbines, making them more efficient. Usually, PYSZ (ZrO 2 þ 7-8% Y 2 O 3 ) is used as material for TBCs because of its phase stability up to high temperatures and its low thermal conductivity.…”

The paper gives an overview on the modeling activities on plasma sprayed thermal barrier coating in the frame of TFB 63. In the first part, through‐process modeling of the APS deposition of a ZrO2 based TBC is described. Starting from simulation of the plasma jet, heat transfer into the powder particles, particle melting, particle impact on the substrate surface, and solidification is simulated. A homogenization method is introduced to describe the mechanical properties of the resulting TBC. The second part shows simulation of interdiffusion and phase transformations of MCrAlY and intermetallic oxidation protection coatings on several cast Ni‐base alloy substrates. Finally, FEM‐based damage simulation of oxidation protection coatings by transversal fatigue cracks during thermomechanical fatigue loading as well as by delamination of the TBC during thermocyclic loading is discussed.

“…For zinc wires, their surface tension r at molten state can be related to their instantaneous temperature T x and melting temperature T m in°K [21] as r=r o +r T (T x )T m ), which can be rearranged as (T x )T m )=(r)r o )/r T (where r o and r T are some constant values). In spraying, the melt rate of metal wires is controlled by the wire-feeding rate that is in turn governed by the applied electrical potential across the wires and the speed of wire driving motor.…”

Repetitively prototyping several prototypes of the same component using currently available rapidprototyping equipment can be very costly. Substantial savings can be attained with the use of a metal spray process to produce a crust shell on a rapid-prototyping pattern coated with mould release agent (PVA), and then backing the crust with aluminium granules so as to form rapid mould/tooling (RT). The smoothness of the innermost spray layer and its dimensional accuracy in relation to the RP prototype are factors that ensure good quality of parts replicated by RT. This paper establishes a preliminary model for predicting the upper bound of the former and the lower bound of the latter, which have been experimentally verified by arc spraying zinc onto PVA. The theoretical model permits the prediction of spraying parameters for controlling the achievable surface finishing and dimensional accuracy of a spray in RT production.
