“…[6][7][8][9] HAp-coated materials tend to show better biocompatibility, bone-forming ability, and osteoconductivity when compared to materials without a HAp coating. [10][11][12][13] Various HAp coating methods, such as sol-gel coating, [14][15][16] dip coating, [17,18] electrochemical deposition, [19,20] electrophoretic deposition, [21,22] plasma spraying, [23,24] sputter coating, [25,26] hot isostatic pressing, [27][28][29] and biomimetic coating, [30,31] have been developed in the past. However, most of the existing methods require a separate synthesis process for HAp coating.…”

Owing to enhanced biocompatibility and osseointegration, hydroxyapatite (HAp) coatings are often applied to biomedical devices that are implanted directly on the bone. Although various HAp coating techniques have been developed, they are restricted due to the time-consuming HAp synthesis and additional coating processes. Herein, the development of a rapid single-step method for simultaneous synthesis and coating of HAp via nanosecond laser surface treatment is described. In the conventional HAp-coating method, the resulting interface between the HAp layer and the base material is clearly distinguished. However, in this method, HAp synthesis and coating occur simultaneously via the melting of the base material (i.e., titanium, polyetheretherketone, and polycaprolactone) to form a gradient HAp-base material composite coating layer. The resultant coating layer on a titanium surface exhibits a binding force of 31.7-47.2 N, which is sufficient for medical implant applications. Changing the laser irradiation conditions provides quantitative adjustment of the HAp formation process and coating layer thickness. Furthermore, the resulting HAp coating layer better facilitates the attachment of bone cells. These results offer a breakthrough in the surface treatment of bone-bonding sites of metal and polymer biomedical devices.

“…It was reported that plasma sprayed ceramic coatings are able to increase performances in bonding strength, hardness, wear and corrosion resistance, etc. There is no doubt that the improvements of bioceramic coating are mainly related to thermal stability, phase and chemical composition, as well as microstructure [45]. Plasma sprayed bi-layer coating containing Al 2 O 3 -13 wt.% TiO 2 and ZrO 2 layer was successfully deposited on Ti-13Nb-13Zr substrate, and the corrosion and wear resistance properties of the coatings were significantly increased due to its lower porosity and higher adhesion strength [46,47].…”

Surface Modification of Biomedical Titanium Alloy: Micromorphology, Microstructure Evolution and Biomedical Applications

With the increasing demand for bone implant therapy, titanium alloy has been widely used in the biomedical field. However, various potential applications of titanium alloy implants are easily hampered by their biological inertia. In fact, the interaction of the implant with tissue is critical to the success of the implant. Thus, the implant surface is modified before implantation frequently, which can not only improve the mechanical properties of the implant, but also polish up bioactivity and osseoconductivity on a cellular level. This paper aims at reviewing titanium surface modification techniques for biomedical applications. Additionally, several other significant aspects are described in detail in this article, for example, micromorphology, microstructure evolution that determines mechanical properties, as well as a number of issues concerning about practical application of biomedical implants.
