“…The ED involves the following steps: (i) surface treatment, (ii) catalytic activation, (iii) electroless process, and (iv) annealing treatment [11]. The deposition bath is formed by a metal salt, a complexing and reducing agent, a stabilizer, an inhibitor, and others (pH regulators, wetting and polishing agents) [11,12]. Factors such as temperature, time, pH, and chemical composition directly influence the morphology, composition, and final structure of electroless coating, as well as the electrical and magnetic properties [12][13][14].…”

Factors such as temperature, time, pH, and chemical composition directly influence the morphology, composition, and final structure of electroless coating, as well as the electrical and magnetic properties [12][13][14]. For example, thickness and size grain dependence were observed with immersion duration of the substrate in the deposition bath [15]; pH has a direct relation with the reaction rate [14]; the activation process was shown to control the rate and mechanism of coating deposition [16], while substrate morphology affects the roughness, hydrophobicity, and thermal conductivity of the electroless coating [17].…”

Electroless Ni-Mo-P coatings were deposited onto ceramic tiles in order to be employed as electrodes for the electrodeposition of ZnO and Cu2O heterojunction layers. Varying conditions, such as duration, annealing of the electroless coating and applied potential, and duration for ZnO electrodeposition were studied in order to optimize the properties of the ZnO/Cu2O heterojunctions toward improved photoelectrical performance. The coatings were evaluated in terms of morphology, crystalline structure, and by electrochemical and photoelectrical means. The obtained results indicated that a prolonged annealing treatment at low temperature is beneficial to improve the roughness and electrical conductivity of the Ni-Mo-P coating to further enhance the electrodeposition of ZnO. The morphology analysis revealed continuous and homogeneous Ni-Mo-P coatings. The formation of cube-like Cu2O crystals with larger grain size was induced by increasing the deposition duration of ZnO. The properties of ZnO layer are much improved when a higher cathodic potential is applied (−0.8 V) for 1 h, resulting in optimum photoelectric parameters as 1.44 mA·cm−2 for the JSC and 760.23 µV for the VOC value, respectively, for the corresponding heterojunction solar cell.

“…Se pueden agregar otro tipo de sales metálicas a la solución química con el fin de mejorar ciertas características del recubrimiento. Por ejemplo, el fósforo incrementa la resistividad del recubrimiento metálico y permite su uso a elevadas temperaturas (B. H. Liu et al, 2013), mientras que el molibdeno actúa como un agente estabilizante y elemento solubilizante de la fase cristalina de níquel que permite mejorar la estabilidad térmica (H. Liu, Wang, Liu, Harrison, & Thompson, 2016;B. Zhang, 2016d), la dureza (Mallory & Hajdu, 1990) y las propiedades de resistencia a la corrosión (Hong Liu & Qian, 2018;Reyes-Tolosa, Ajami, et al, 2010) del recubrimiento metálico.…”

Ni-Mo-P coatings are obtained at the surface of ceramic substrate by electroless deposition using palladium as a surface catalyst. The influence of catalyst activation conditions on coatings' properties was assessed by structural, morphological, electrical, mechanical measurements and adhesion strength by using X-ray diffraction, field emission scanning electron microscopy, atomic force microscopy, Hall effect and nanoindentation techniques, respectively. The results indicated the formation of dense, continuous and uniform coatings consisting mainly of Ni. The coatings obtained at 300 °C for 12 h exhibited the best electrical properties, namely resistivity of 9.32 μΩ cm, smaller roughness (R a 0.090 µm) and average mechanical properties. The adhesion tests showed a firm adherence of the Ni-Mo-P coatings to the ceramic surface. The results of this study could offer an approach for obtaining conducting ceramic substrates in order to be employed in photovoltaic applications. The performance of demonstrative heterojunction solar cell obtained with such metallized ceramic is indicative of the high potential of the Ni-Mo-P electroless coatings for functional ceramics.
