“…For example, electroplating coatings are very thin and the interface between coating and substrate is so poor that the electroplating coatings are susceptible to being peeled off from substrate during service. For thermal spraying, it has relatively higher efficiency, but the sprayed coatings are mechanically bonded to substrate and contain many pores and micro-cracks, resulting in premature failure therefore a decrease in service time [6,7].…”

To enhance the wear resistance and corrosion resistance of Ni-based coatings, carbon fibers reinforced nickel-based composite coatings (CFs/Ni) were fabricated on the surface of 1Cr13 stainless steel by laser cladding (LC). The microstructure characteristics, microhardness, wear and corrosion performances of the composite coatings were investigated. The results show that CFs can effectively improve the corrosion and wear resistances of Ni-based coatings. With increasing laser scanning speed, the morphology of CFs in composite coatings is more integral and the corrosion

“…The NA2 composite coating has the highest microhardness, of 362.2 HV in all composite coatings. The Mo could act as the solution-strengthening phase, to greatly increase the microhardness of the composite coatings [39]. Figure 6 shows the open circuit potential (OCP) evolution before, during and after the tribocorrosion of composite coatings in artificial seawater.…”

NiAl matrix composite coatings were prepared using atmospheric plasma spraying (APS). The mechanical and tribocorrosion properties of the NiAl matrix composite coatings, incorporated with Cr2O3 and Mo, were investigated, and the synergistic effect between corrosion and wear was studied in detail. The microhardness of the composite coating improved from 195.1 to 362.2 HV through the addition of Cr2O3 and Mo. Meanwhile, the Cr2O3 and Mo phases were distributed uniformly in the composite coatings. The X-ray diffraction (XRD) peaks of Ni-based solid solution slightly shifted to the right after adding the Mo. This was probably due to the solid solution of Mo into the matrix. The NiAl–Cr2O3–Mo composite coating had the lowest corrosion current density, wear rate and friction coefficient of 9.487 × 10−6 A/cm2, 3.63 × 10−6 mm3/Nm, and 0.18, in all composite coatings as well as showing excellent tribocorrosion properties.

En el presente trabajo se realizaron recubrimientos superficiales de carburo de tungsteno sobre un substrato de acero del tipo AISI 1018 mediante el proceso de rociado térmico utilizando tres diferentes tipos de flama: carburante, neutra y oxidante. Los resultados indican que los valores de porosidad son menores bajo condición de flama carburante con una microestructura compuesta de partículas semi-fundidas y sin fundir, de estructura no laminar, y con presencia de líneas de óxidos. La dureza medida en el recubrimiento de condición carburante resultó por encima de los 1000Hv debido a la presencia de partículas duras de WC y de W2C. Así mismo, los recubrimientos realizados bajo condición de flama carburante resultaron en una resistencia al desgaste bastante aceptable de acuerdo al análisis realizado bajo diferentes condiciones de carga y tiempo de deslizamiento. Finalmente se concluye que las partículas presentes de carburo de tungsteno y la dureza relativamente de éstas influyeron en la resistencia al desgaste de estos recubrimientos a pesar de la porosidad aparente observada. Palabras clave: Carburo de tungsteno, desgaste por deslizamiento, porosidad, rociado térmico.
