“…In this case, after 30 min of experiment the formation of micrometer-sized pits was visible; after 90 min, these pits propagated across the film surface producing large pores, whereas after 150 min most of the film was removed from the silicon substrate. The authors concluded that cavitation erosion resistance is inversely proportional to the roughness of the diamond film, which is in agreement with the findings by Deuerler et al [23] that nanocrystalline films are more resistant to cavitation erosion.…”

“…Therefore, the substantial degradation of the BDD surface shown in Fig. 1c and f brought about by the long cathodic pretreatment may have been exacerbated by the consequent increase of the temperature, analogous to what occurred in cavitation erosion tests [23]. Similar surface degradations are also found for 2000 and 8000 ppm BDD electrodes after the same cathodic pretreatments.…”

“…Deuerler et al [23] studied the adhesion and wear behaviour of micro-and nanostructured crystalline diamond films by a cavitation test, using the ultrasonic technique to stimulate their degradation. These authors showed that diamond surfaces might be effectively eroded under those conditions.…”

The electrochemical activation and physical degradation of boron-doped diamond (BDD) electrodes with different boron doping levels after repeated cathodic pretreatments are reported. Galvanostatic cathodic pretreatment passing up to -14000 C cm -2 in steps of -600 C cm -2 using -1 A cm -2 caused significant physical degradation of the BDD surface, with film detachment in some areas. Because of this degradation, a great increase in the electrochemically active area was observed in Tafel plots for the hydrogen evolution reaction (HER) in acid media. The minimum cathodic pretreatment needed for the electrochemical activation of the BDD electrodes without producing any observable physical degradation on the BDD surfaces was determined using electrochemical impedance spectroscopy (EIS) measurements and cyclic voltammetry: -9 C cm -2 , passed at -1 A cm -2 . This optimized cathodic pretreatment can be safely used when electrochemical experiments are carried out on BDD electrodes with doping levels in the range between 800 and 8000 ppm.

A technique to deposit titanium films with rutile-TiO 2 layer at the top was carried out in two steps: the deposition of titanium by means of cathodic vacuum arc (CVA) followed by a thermal oxidation technique was investigated. As a result, well adhering rutile films occurred in the near surface region. The uncoated and coated substrates were investigated using X-ray diffraction (XRD) and energy dispersive x-ray spectroscopy (EDX). The presence of rutile phase titanium dioxide and titanium metal was confirmed by XRD. Cavitation erosion was used to investigate the protective adhesion properties of these coatings. Cavitation erosion tests confirmed that rutile TiO 2 films with a Ti inter layer adhere well to stainless steel substrates and protect the substrate from erosion.
