“…The influence of coatings structure on the electrical conductivity and consequently on the electrochemical behavior of DLC coatings has been previously reported by Wang et al [23]. The R P and CPE values obtained for Ti/TiN/TiCN interlayer suggest that this coating presents a poor protective behavior, which has been previously reported by other authors in similar coatings (SS316L/Ti/TiN) [36,37,40]. Moreover, regarding that the first layer of this coating is titanium, the contact between SS316L and Ti, results in the formation of a galvanic couple, which can also exert a strong influence in the electrochemical response.…”

“…Therefore, fabrication processes in the inert atmosphere, e.g. physical vapor deposition (PVD) or low-pressure plasma spraying (LPPS) have been the most promising process for forming titanium coatings with low oxygen content [28,29]. It would be much more advantageous if it becomes possible to coat Ti in air for the following reasons: higher operation efficiency, no limitation to the size of the work, and more freedom in the fabrication site.…”

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.

In this work the corrosion resistance of AISI 316L biomedical stainless steel was assessed through electrochemical impedance spectroscopy (EIS) measurements in Hanks' solution at 37 °C. Specimens were immersed in the electrolyte during 21 days. Semi‐conducting properties of the passive film naturally formed on the surface of the metallic material during the test were evaluated through the Mott–Schottky approach. The aim was to investigate the correlation between corrosion resistance and semi‐conducting properties in the physiological solution. The corrosion resistance was found to decrease with the immersion time. The density of defects in the passive film increased accordingly as indicated by the Mott–Schottky plots. The passive film presented a semi‐conducting behavior with a duplex character. Above the flat band potential the behavior was typical of an n‐type semiconductor whilst below such value it was typical of a p‐type semiconductor. The results from EIS measurements and Mott–Schottky were in good agreement, suggesting that the corrosion resistance of biomedical stainless steels may be associated with the semi‐conducting properties of the passive films formed during immersion in physiological medium.
