Mechanical properties of suspension plasma sprayed hydroxyapatite coatings submitted to simulated body fluid

Calcium orthophosphate deposits: Preparation, properties and biomedical applications

“…Namely, there are atmospheric [149][150][151], vacuum and/or lowpressure [152,153], powder [10,123], suspension [154][155][156][157][158][159][160], liquid and/or solution [156], gas [161,162], gas tunnel type [163][164][165], radio frequency [166,167], low energy [168], etc. plasma spraying techniques and all of them are used to deposit CaPO 4 .…”

Atmospheric plasma sprayed silica–hydroxyapatite coatings on magnesium alloy substrates

“…The amorphous material and other phases are significantly more soluble than hydroxyapatite, therefore these are preferentially dissolved in vitro [32]. The advantage of this method is that plasma spraying is a well-established tool to deposit HAP on metallic implants [7]; also, many studies were performed to investigate the microstructure, phase transformation, influence of post-treatment on the properties of sprayed HAP in vitro and in vivo [33,34].…”

Effect of heat treatment on microstructures and mechanical behavior of porous Sr–Ca–P coatings on titanium

“…The coating adhesion was measured using the scratch test to be about 13.1 N. The HA coating, which was prepared using electrochemical deposition, was scraped off from the titanium substrate at a load of 20 N [3]. A study [24] synthesized HA powder via a wet method using Ca(NO 3 ) 2 and (NH 4 ) 2 HPO 4 and then used the powder to form a suspension with water and alcohol. An HA coating was then deposited onto titanium using plasma spraying technique.…”
