“…There are several studies on the application of a ceramic coating to reinforce mechanical strength [9][10][11]. Hard ceramic coatings have a wide range of applications, such as turbine blades [12], furnace bricks [5], and pipelines [13]. In addition, functionally gradient materials (FGMs) have been developed to meet the requirement of certain materials for a continuously varying property, such as hardness, dielectric constant, or thermal resistance, from one surface to the other.…”

Adhesion and homogeneity of the coating-substrate were analyzed on the basis of the establishment of coating mineralogy. Substrate raw materials used were kaolin clay and a calcined alumina 4 µm; a series of higher density ceramic coatings were deposited using calcined aluminas 0.5 µm and 4 µm, silica fume, and talc. The dip coating technique was applied to all substrates and later sintered at 1300 ºC. Shrinkage and density of coatings mixtures and substrate were separately evaluated. X-ray diffraction was utilized to identify the crystalline phases present in the coatings, while optical and electron microscopy were employed for the structural characterization of the coatings. Coatings exhibited lower shrinkage compared to the substrate. Among the specimens that exhibited good adhesion, cracks were observed to extend parallel to the substrate surface. The presence of cristobalite on the coating indicated that the failure mechanism involved buckling. The crack dimension presented on the coating decreased after adding talc to the mixture.

“…Along with the strict requirement of environmental protection, WC-10Ni coating by the high-velocity HVOF has significant strength in terms of wear resistance [11], corrosion resistance [12], and fatigue resistance of the coating as a cleaning technology of the modern industrial development [13]. Compared with others, the HVOF coating exhibits high binding strength [14,15], high hardness [16], and low porosity [17,18] and, thus, could effectively resolve the wear and corrosion problems on the surface of the hydraulic support column [19].…”

The hydraulic support column bears loading and makes reciprocating motion ceaselessly for extended periods, so its service life is far shorter than that of the overall hydraulic support. This paper offers a comparative study on the surface coating of hydraulic support columns with hard chrome plating and high-velocity oxygen fuel (HVOF) thermal spraying refabricating to analyze the impact of different refabricating processes on the microstructure, hardness, corrosion resistance, and wear resistance of the coating (plating). The result shows that the structure of the HVOF coating is uniformly compact, and the HVOF WC10Co4Cr coating has better wear resistance, more than four times that of hard chrome plating. In the neutral salt spray test, the HVOF Ni60 coating shows rustiness at 720 h of the test, which suggests its corrosion resistance is nearly five times that of hard chrome plating. Hence, under the harsh corrosive wear environment, the refabricating HVOF Ni60 is a more suitable replacement for the hydraulic support column coating than the hard chrome plating. Thus, the HVOF Ni60 coating could be an effective replacement for hard chrome plating.

“…Estos métodos permiten caracterizar y probar los recubrimientos encontrando fallas como lo son: ampollamientos, deformaciones, discontinuidades, porosidades, absorción de agua entre otras, todos los ensayos y pruebas que se realizan a las juntas (uniones) de tubería recubiertas para garantizar la continuidad en los recubrimientos y en el caso de las mediciones de espectroscopia, la idea es obtener un perfil de desgaste durante el tiempo y verificar en qué momento se producen fallas de acuerdo a las condiciones de operación de los fluidos [2].…”

El presente paper describe el diseño y la construcción de un equipo que permite la verificación de conexiones soldadas de tuberías recubiertas internamente, utilizadas en el transporte de fluidos del sector petrolero, permitiendo caracterizar las diferentes fallas que ocurren en los procesos de soldadura e instalación antes de poner en operación los sistemas de transporte, este equipo permite hacer la detección de fallas y problemas que pueden presentarse en los procesos de instalación, haciendo uso de la técnica de espectroscopia de impedancias electroquímica (EIS). El equipo cuenta con un sistema mecánico para el desplazamiento del sistema de medición a lo largo de tuberías de 6 a 12 pulgadas de diámetro. Permite detectar fallas en los recubrimientos como lo son ampollas, grietas, fisuras y quemaduras producidos principalmente por el transporte y las altas temperaturas en los procesos de soldadura. El sistema cuenta con un equipo de medición basado en la técnica de espectroscopia de impedancias (EIS) y una interfaz de usuario que permite mover el dispositivo a lo largo de la tubería, controlar el punto de medición realizando barridos en 4 puntos principales a 0°,90°,180° y 270°, almacenando los datos de medición y procesándolos en una interfaz gráfica en Matlab, el diseño de portabilidad cuenta con un sistema de comunicación Bluetooth y un cable umbilical de alimentación para energizar el sistema y hacer la conexión a tierra de la tubería. Los ensayos realizados durante el desarrollo del equipo permitieron caracterizar la impedancia de varias superficies y asociar rangos a las diferentes imperfecciones en los recubrimientos.
