In recent years, coating processes based on the impact of high-velocity solid particles such as cold spraying and aerosol deposition have been developed and attracting much industrial attention. A novel coating process called 'warm spraying' has been developed, in which coatings are formed by the high-velocity impact of solid powder particles heated to appropriate temperatures below the melting point of the powder material. The advantages of such process are as follows: (1) the critical velocity needed to form a coating can be significantly lowered by heating, (2) the degradation of feedstock powder such as oxidation can be significantly controlled compared with conventional thermal spraying where powder is molten, and (3) various coating structures can be realized from porous to dense ones by controlling the temperature and velocity of the particles. The principles and characteristics of this new process are discussed in light of other existing spray processes such as high-velocity oxy-fuel spraying and cold spraying. The gas dynamics of particle heating and acceleration by the spraying apparatus as well as the high-velocity impact phenomena of powder particles are discussed in detail. Several examples of depositing heat sensitive materials such as titanium, metallic glass, WC-Co cermet and polymers are described with potential industrial applications.

“…There are various types of SFF innovations, even so, the laser based forms are mostly utilized in creating functional graded material [6]. Laser based SFF process for FGM [7] include: (i) laser cladding based strategy [8,9], and (ii) Selective Laser Sintering (SLS) [10,11]. SFF includes five essential steps [12].…”

Abstract.Material engineering has become one of the corner stones in various engineering applications. The scientific alteration of base materials into various inorganic and organic compounds has resulted in the development of Functionally Graded Material (FGM). FGM can be described as a cutting edge material in which the particular material's properties could be made varied as the dimension changes. The aims of this study was to review on FGM's applications and its manufacturing processes. In addition, the mathematical idealization of the FGM was also reviewed. Based on the review, since FGMs are highly heterogeneous, it can be idealized as their mechanical properties changes smoothly with respect to their spatial coordinates. Nonetheless, in order to analyze FGMS in an efficient manner, the homogenization schemes are needed to be simplified from their complicated heterogeneous microstructures. Closed-form solutions of some fundamental solid mechanics' problems can be obtained by this idealization. Conclusively, FGM is unique in relation to any of the individual materials that structures it. Suggestively, this provide a limitless possibility for future engineering applications.

Oxidation behavior of plasma-sprayed stabilized zirconia/Al coated polymer matrix composites

The stabilized zirconia/Al coatings were fabricated on the polymer substrate via plasma spraying. Thermal shock resistance and thermal oxidation resistance of the specimens at different temperatures were evaluated. Due to the increased interface stress and substrate oxidation, the coating lifetime reduced with increasing the temperature. The Al-YSZ coatings provided good oxidation resistance, the weight loss and weight loss rate of the specimens decreased greatly and the service lifetimes were prolonged. After oxidation at 673K or 723K, the coatings exhibited a clean interface bonding without visible defects, while the weight loss was primarily attributed to oxygen penetration and heat transfer. 15 decrease as compared with those of substrate, and the oxidation time for 5.0 wt.% weight loss is prolonged during oxidation in air at 673K.Similarly, no apparent defects or other destructions derived from oxidation can be discovered from the specimens coated with Al-YSZ coatings by comparing the specimens before and after thermal oxidation test at 723K for 13 h (Figure 6c and d). Figure 8 displays the curves of weight loss and weight loss rate of the specimens uncoated and coated with Al-YSZ coating during oxidation in air at 723K. As noted from Figure 8a and b, the weight loss and weight loss per unit area of the specimen coated with Al-YSZ coating are also greatly decreased in comparison with that of substrate. From these curves, after oxidation in air at 723K for 13 h, the weight loss and weight loss per unit area of substrate are 20.76 wt.% and 38.89 mg cm -2 , while that of the specimen coated with Al-YSZ coating are reduced to 4.73 wt.% and 13.17 mg cm -2 respectively. It is obvious that the weight loss and weight loss per unit area of the specimen are sharply lessened during oxidation at 723K, which is resulted from the protection of Al-YSZ coating. As shown in Figure 8c, however, the weight loss rates of specimens represent different trends during oxidation at 723K as compared with that of specimen oxidized at 673K. From Figure 8c, the weight loss rate of substrate displays an increase tendency along with the oxidation time extending. Nevertheless, owing to the protection of Al-YSZ coating, the weight loss rate of specimen is decreased after oxidation for the same time and it also slowly increases with the raise in oxidation time. After oxidation at 723K for 13 h, the weight loss rates of the specimens uncoated and coated with Al-YSZ coating are calculated to be 2.99 mg cm -2 h -1 and 1.01 mg cm -2 h -1 , respectively.Correspondingly, by comparing with oxidation behaviors of specimens during oxidation at
