“…74 The powder metallurgy technique has four basic steps to produce FGMs: mixing, stacking, compaction, and sintering. 75 The very first step in powder metallurgy is mixing. During this step, different compositions of powders are mixed based on the required grading.…”

Functionally graded materials (FGMs) are specially designed composite materials that gradually change their material properties. This distinctive property of materials comes with new challenges in the design and manufacturing sector. For such challenges, the best options are material property computation and material modelling using different computational materials science (CMS) algorithms. This review paper provides enriched information on CMS with an overview of the available FGM production techniques with a detailed study of FGM use in biomedical applications based on the available literature over the past couple of decades.

“…Furthermore, an oxygen concentration gradient exists on the substrate side, and as a result, the hardness gradually increases from the metal substrate toward the oxide layer near the interface [12]. It is suggested that the relaxation of the interfacial stress by the oxygen concentration gradient is one of the reasons for the remarkable increase of the interfacial strength in addition to the high exfoliation resistance of the oxide layer itself by the above-mentioned dense structure and the interfacial structure continuity.…”

The authors proposed an oxide coating on Ti alloys for the dental abutment tooth, and they had reported that Ti–29Nb–13Ta–4.6Zr (TNTZ) alloy forms a dense oxide layer by high-temperature oxidation. On the other hand, CP Ti forms a multilayered oxide consisted of rutile monolayers and the void layer. This morphological change by alloying is supposed to be mainly caused by Nb addition in Ti since the dense oxide layer of TNTZ mainly consists of rutile TiO2 and TiNb2O7. Therefore, in this study, oxidation behaviors of various range of Nb content of Ti-xNb alloys (x = 1 ~ 32 mol%) were investigated, and exfoliation resistance was evaluated. And in this paper, the oxide/metal interfacial microstructure of oxidized CP Ti, TNTZ alloy, and Ti-Nb alloy was studied by a transmission electron microscopy (TEM) and by a scanning transmission electron microscopy with an electron dispersive spectroscopy (STEM-EDS). The cross-sectional observations suggested that the substrate was gradually oxidized during heat treatment, and nucleation and grain growth of TiO2 and TiNb2O7 proceed at the metal/oxide interface. Consequently, the gradual oxidation process in TNTZ and Ti-Nb alloys could lead to its continuous interfacial microstructure and dense oxide structure, which can achieve high exfoliation resistance.

“…Over the past years, many promising examples of using SPS technology in manufacturing functionally graded coatings were presented. One of the most studied topic in that field concerns bioactive coatings [40]. Cattini et al studied in the Universities of Limoges and of Modena bioactive glass/hydroxyapatite (HA) functional coatings with various designs, namely: composite, duplex, and graded coatings [41,42].…”

The paper briefly describes major thermal spray techniques used to spray functionally graded coatings such as atmospheric plasma spraying, high velocity oxy-fuel spraying, suspension and solution precursor plasma spraying, and finally low and high pressure cold gas spray method. The examples of combined spray processes as well as some examples of post spray treatment including laser and high temperature treatments or mechanical one, are described. Then, the solid and liquid feedstocks used to spray and their properties are shortly discussed. The reviewed properties of functional coatings include: (i) mechanical (adhesion, toughness, hardness); (ii) physical (porosity, thermal conductivity and diffusivity, thermal expansion, photo-catalytic activity), and; (iii) bioactivity and simulated body fluid (SBF) corrosion. These properties are useful in present applications of functionally graded coatings as thermal barriers, the bioactive coatings in prostheses, photo-catalytic coatings in water treatment, coatings used in printing industry (anilox and corona rolls). Finally, some of the future possible fields of functional thermal sprayed coatings applications are discussed, e.g., to coat polymer substrates or to use the cheap technology of low pressure cold gas spray method instead of expensive technology of vacuum plasma spraying to obtain bond coatings.
