“…In addition, some studies have used lower velocities (~300 m/s). These techniques have been called "low velocity oxyfuel (LVOF)" [256] or "flame spraying" [257]; in the case of LVOF spraying, the specific energy and power consumption required to melt the CaPO4 powder is lower than in HVOF; thus, LVOF is considered more economical. At the end of this section, mention should be made of the existence of the High Velocity Suspension Flame Spraying (HVSFS) process, developed at the Institute for Manufacturing Technology of Ceramic Components and Composites at the University of Stuttgart, Germany, which appears to be an improvement on HVOF spraying.…”

A The present overview describes various production techniques for biocompatible calcium orthophosphate (abbreviated as CaPO4) deposits (coatings, films and layers) on the surfaces of various types of substrates to impart the biocompatible properties for artificial bone grafts. Since, after being implanted, the grafts always interact with the surrounding biological tissues at the interfaces, their surface properties are considered critical to clinical success. Due to the limited number of materials that can be tolerated in vivo, a new specialty of surface engineering has been developed to desirably modify any unacceptable material surface characteristics while maintaining the useful bulk performance. In 1975, the development of this approach led to the emergence of a special class of artificial bone grafts, in which various mechanically stable (and thus suitable for load-bearing applications) implantable biomaterials and artificial devices were coated with CaPO4. Since then, more than 7500 papers have been published on this subject and more than 500 new publications are added annually. In this review, a comprehensive analysis of the available literature has been performed with the main goal of finding as many deposition techniques as possible and more than 60 methods (double that if all known modifications are counted) for producing CaPO4 deposits on various substrates have been systematically described. Thus, besides the introduction, general knowledge and terminology, this review consists of two unequal parts. The first (bigger) part is a comprehensive summary of the known CaPO4 deposition techniques both currently used and discontinued/underdeveloped ones with brief descriptions of their major physical and chemical principles coupled with the key process parameters (when possible) to inform readers of their existence and remind them of the unused ones. The second (smaller) part includes fleeting essays on the most important properties and current biomedical applications of the CaPO4 deposits with an indication of possible future developments.

“…A 0.5 bar air pressure gauge was available to supply combustion gas. The HA coating's thickness, which ranged from 56 μm to 70 μm, resulted in an adhesive strength of 4.12 MPa [22]. Further research needs to consider variations in spray gun shooting distance and other pre-heat temperatures.…”

“…For biomedical implant applications, green mussel shells have promising prospects. However, there is a large difference in the elastic modulus of green mussel shells and metal biomaterials, so the adhesion strength is low [22]. Therefore, this research aims to examine the AISI 316L biomaterial coated with HA originating from waste using the flame spray method.…”

This study aimed to determine the effect of preheating AISI 316L metal substrate on the adhesion strength of the hydroxyapatite (HA) layer derived from green mussel shell waste deposit by the flame spray method. The deposition experiment was carried out in a spray gun with a distance of 10 mm with preheat of 200°C, 400°C, and 600°C. A sample without preheating was also a comparison. An optical microscope was for assessing the thickness and uniformity of the HA surface layer. The adhesion strength of the coatings followed the ASTM D4541 Standard. As a result, the adhesion strength of the HA coating increases with increasing preheat temperature. However, using Image-J software, at an initial heating temperature of 600 °C, the adhesion strength of the coating changed from adhesion- to adhesion-cohesive strength, leading to an increase in coating strength noted. The result can add knowledge to understanding the flame spray method for the HA-coated from green mussel shell waste on AISI 316L. The results obtained can increase knowledge to understand the method of flame spraying on HA-coated green mussel shell waste on AISI 316L. Preheat temperature, spray gun shooting distance, HA powder release, oxygen gas pressure, and LPG gas pressure can be used as references.

“…The synthesis of HAp can vary in material and method, for example using green mussel shell (Perna viridis) waste with the hydrothermal method, which has already been conducted in the previous study [12]. This green mussel shell HAp has been coated on metallic implant material to improve its biocompatibility properties [13].…”

The use of biogenic waste for multipurpose materials has started to be encouraged in the current decade to support the world’s environmental sustainability campaign. Biogenic calcium phosphate-derived materials are potential biomaterials because of their similar properties to human bone. This paper used hydroxyapatite (HAp) powder derived from green mussel shells (Perna viridis) to coat the AISI 316L metallic implant material using the electrophoretic deposition coating method. In this study, the post-deposition withdrawal speeds of 5mm/s, 3mm/s, and 1mm/s were varied to find their effect on the quality of the HAp coating layer. Crystallography, micrography, and image processing were used to characterize the coating and calculate the percentage of HAp layer and cracks. The crystallographic data shows the HAp peaks, which conclude that the green mussel shells HAp successfully coat the substrate and can be used to coat the AISI 316L implant material. However, the appearance of the substrate crystal peaks and color difference on high withdrawal speed specimens conclude that the coating layer has cracks. In conclusion, the emergence of cracks can be minimized using 1mm/s post-deposition withdrawal speed and eventually produce high-quality HAp coating.
