“…Moreover, remelting of the coatings also influenced the surface roughness of the cold-sprayed deposits, as reported in Table 3. Phase analysis of the powder and as-sprayed coatings are reported in our previous work [15]. Laser treatment of cold-sprayed coatings leads to a change in the phase of the coatings, which is reported in Figure 4.…”

“…Similarly, a larger beam diameter will distribute heat in relatively more area leading to a lesser heating effect and lower temperature. Our previous work discussed the microstructural characterization of as-sprayed coatings [15]. The cross-sectional SEM/EDS micrographs of the laser-treated coatings are shown in Figure 2.…”

“…Commercially available titanium (Ti) and baghdadite (BAG) were used as the starting powdered materials for cold spraying. As discussed in our previous work, four distinct compositions were prepared and coated [15]. Once the coatings were deposited, laser post-treatment was performed using a continuous-beam fiber-laser source.…”

“…Composite powders are deposited on various substrates, including aluminum, copper, and steel, using cold-spray technology [12][13][14]. Kumar et al [15] deposited a metal matrix coldsprayed composite coating on austenitic stainless-steel (316L SS) substrate for biomedical applications and discussed their microstructure and mechanical and electrochemical behavior. The retention or fracture of ceramic particles into the coatings in cold spray leads to high porosity, which sometimes adversely affects the performance of the cold-spray deposits.…”

This study aims to enhance the corrosion performance of cold-sprayed titanium/baghdadite (Ti/BAG) bio-composite coatings. Laser post processing was performed to reduce porosity and improve mechanical properties. The process parameters for laser treatment of cold-sprayed coatings were verified experimentally using scanning electron microscopy (SEM) and a thermal imaging camera. The laser-treated coatings are analyzed with SEM, energy-dispersive spectroscopy (EDS), ImageJ software, and X-ray diffraction (XRD). Furthermore, electrochemical analysis of the laser-treated and as-sprayed coatings was conducted in Ringer’s solution. The results of this study revealed that laser treatment helps significantly in enhancing resistance to corrosion for Ti/BAG composite coatings in a Ringer’s solution. The reduction in porosity and surface roughness is ascribed as the reason for their superior performance relative to as-sprayed coatings.

“…BAG has better biological as well as mechanical properties. Corrosion resistance is enhanced by increasing the BAG content and thickness of coating beyond 200µm act as a barrier to corrosion [27].Further, Ti-15%BAG has lowest wear rate where wear debris and plastic deformation is less. The micro hardness at this composition is best and is recommended for orthopedic implants [28].…”

The use of orthopedic implants is increasing worldwide as the population of older people is growing. Metals and their alloys like stainless steel, cobalt-chromium alloys, and titanium alloys are widely used as implant biomaterials for the treatment of orthopedic joint failure because of their biocompatibility and good mechanical properties. However, these materials offer poor osseointegration due to their bio-inert nature. Hydroxyapatite, a bioactive material, has similar properties to bone tissue and helps in improving bone regeneration. It has good osseointegration properties, but it lacks mechanical properties. It has low fracture toughness, wear resistance and poor tensile strength. The carbon reinforced hydroxyapatite can have better mechanical properties as well as biocompatibility. The addition of graphene and carbon nanotubes in HA can also provide antibacterial effects and induce osteogenic differentiation of stem cells. The surface modification process like surface coatings involves the addition of composite materials to have desirable properties. The hydroxyapatite coatings produced by thermal spray are commercially accepted by FDA (Food and Drug Administration). Thermal spray materials can play a vital role in enhancing orthopedic implants' biocompatibility, wear, and corrosion resistance. The coatings can improve the optimal integration to the surrounding tissues and result in increasing the life of implants. The study will focus on the various thermal spray techniques like flame spray, HVOF (High-Velocity Oxygen Fuel), cold spray, and plasma spray that are commonly used in bio-implant applications. The paper will also discuss the different types of biomaterial coatings produced with thermal spray processes by the researchers. Moreover, the comparison of various thermal spray coatings for biomedical applications are also covered.
