“…The estimated theoretical thickness of the electrodeposits was 18 μm. In a previous work it has been demonstrated that the theoretical thickness value match well with the experimental values obtained from cross-section SEM images [24], which points to high current efficiencies [5]. The as-deposited Ti/Zn and Ti/Zn-TiO 2 films were annealed in air at 450°C, using a heating rate of 5°C min −1 , held for 6 h, and then cooled to room temperature.…”

“…The nanocomposite coatings were prepared by the occlusion electrodeposition method, where high surface area TiO 2 nanoparticles are incorporated within the metal matrix, while simultaneously reduction of the metal ions occurs at the interface electrode solution [4,5]. This method has been selected for its versatility and simplicity.…”

“…In 1977, Celis et al, used atomic-absorption spectrometry to determine the amount of alumina in a copper matrix and have shown that this technique can be applicable "with reasonable accuracy" down to 0.02 wt% for 1 g samples . More recently ICP technique was used to estimate the amount of TiO 2 in Zn-TiO 2 composites (Deguchi et al, 2001;Frade et al, 2010). However, it is a rather tedious and time consumption approach, since in most cases the sample has to be dissolved.…”

“…37 Este fato poderá ser atribuído à presença das partículas de TiO 2 incorporadas na matriz metálica. Estudos realizados anteriormente comprovaram que a presença de nanopartículas incorporadas numa matriz metálica promove a diminuição do tamanho de cristalite 38 que, por sua vez, irá permitir uma conversão de uma matriz de Zn a ZnO bem sucedida. 39,40 Segundo Lin et al, 40 a presença das partículas de TiO 2 afeta o crescimento do tamanho de grão da matriz metálica, impedindo o aumento deste durante o processo de recristalização por ação do aquecimento.…”
