“…PM methods are widely used in the production of FGM parts, specifically ceramic FGMs. One of the important advantages of these methods is their ability to produce intricate and complicated shapes out of any metallic or ceramic powders, and it is the best method to produce FGMs out of solid constituents (Tripathy et al, 2017). Shahrjerdi et al (2011) produce metal-ceramic composite FGM by a pressurless sintering method using pure Ti and HA; the compositional gradation was from the metallic (Ti) end to the ceramic (HA) end.…”

Functional gradient materials (FGMs), as a modern group of materials, can provide multiple functions and are able to well mimic the hierarchical and gradient structure of natural systems. Because biomedical implants usually substitute the bone tissues and bone is an organic, natural FGM material, it seems quite reasonable to use the FGM concept in these applications. These FGMs have numerous advantages, including the ability to tailor the desired mechanical and biological response by producing various gradations, such as composition, porosity, and size; mitigating some limitations, such as stress-shielding effects; improving osseointegration; and enhancing electrochemical behavior and wear resistance. Although these are beneficial aspects, there is still a notable lack of comprehensive guidelines and standards. This paper aims to comprehensively review the current scenery of FGM metallic materials in the biomedical field, specifically its dental and orthopedic applications. It also introduces various processing methods, especially additive manufacturing methods that have a substantial impact on FGM production, mentioning its prospects and how FGMs can change the direction of both industry and biomedicine. Any improvement in FGM knowledge and technology can lead to big steps toward its industrialization and most notably for much better implant designs with more biocompatibility and similarity to natural tissues that enhance the quality of life for human beings.
