Abstract:

Thermal spraying technology is a coating deposition process used to modify and repair the surface of materials, which is characterized by the shorter process, simplicity of operation, flexible equipment and ability for large-scale production. With the development of thermal spraying technology and biomaterials, thermal spraying shows huge potential to prepare coatings with good biocompatibility and unique properties (e.g., corrosion-resistance, wear-resistance and bacteriostasis) on orthopedic implant devices, such as hip, knee, ankle and shoulder joints. Due to the advantages of flexibility and versatility in thermal spray processes, thermal sprayed materials can be applied in a broad range of applications in orthopedic implants. This paper first introduces the deposition method used for biomaterials in thermal spraying technology, with a focus on the characteristics, advantages and disadvantages of the three types of spraying techniques. Then, it introduces four commonly used biomedical coating materials and elaborates on the characteristics and limitations of each material in detail, including hydroxyapatite, Ti, ceramics (TiO2, ZrO2 and Al2O3) and bioactive glass. Finally, it discusses the current challenges and proposes the future development direction for thermal sprayed coating in the orthopedic implant devices.
