“…Following mixing and stirring, the wet paint was applied onto one side of a steel beam to form four piezoelectric paint sensors. Before the paint deposition, the surface of the steel beam was pre-treated using a pretreatment solution from Carpenter Chemicals, which is described as a one-step, room-temperature organic phosphating system (Carpenter and Carpenter 2003). The sample mean value of the paint (i.e., coating) thickness is approximately equal to 0.17 mm.…”

Sensors, which collect data for further information processing, are core component of any viable structural health monitoring system. Continuous on-line structural health monitoring can be achieved through the use of advanced sensors developed for real-time structural health monitoring applications. To overcome the problems associated with traditional piezoelectric ceramics, a polymer-based piezoelectric paint material has been developed and recently used for sensors. The piezoelectric paint is composed of tiny piezoelectric particles mixed within polymer matrix and therefore belongs to "0-3" piezoelectric composite. Because of the electro-mechanical coupling properties of piezoelectric paint, the dynamic responses of host structures can be monitored by measuring the output voltage signals from the piezoelectric paint sensor. Piezoelectric paint sensors hold a great potential for dynamic strain sensing applications due to the ease with which their mechanical properties can be adjusted, low fabrication cost, ease of implementation, and conformability to curved surface Additionally, a novel surface crack detection technique has been conceived and validated experimentally, in which cracks of the host structure is detected by observing the measured signals from an piezoelectric paint sensor with multi-electrode configuration. This paper presents this piezoelectric paint-based crack monitoring method as well as validation test data. The piezoelectric paint sensor is ideal for surface crack detection in locations with complex geometry, such as welded joints, which conventional sensors are ill equipped to do.

Phosphate coatings are one of the ancient methods for improvement the corrosion resistance of steels. Many researchers have investigated the effect of process parameters on the structure and properties of these coatings, but the influence of substrate microstructure has been less studied. In this article, the effect of heat treatment of AISI 4130 steel on the surface morphology and corrosion resistance of Zn-Mn phosphate coating has been investigated. The steel substrate was subjected to different heat treatments before coating application. X-ray diffraction, optical and scanning electron microscopy were used for phase and microstructure analysis respectively. The corrosion resistance of the coatings was studied by means of salt spray, potentiodynamic polarisation and electrochemical impedance spectroscopy methods. The results showed that the corrosion resistance of phosphate coatings is greatly influenced by substrate microstructure. The finer the steel microstructure, the more condensed becomes the coating morphology and the better its corrosion resistance.

“…Treatment of steel sheet by immersion or spraying with phosphating bath is accompanied with the formation of adhesive and porous phosphate layer. With the development of modern industry, many new phosphating processes have been investigated [3][4][5][6][7][8]. Now the phosphating process is widely applied to mass production and progressing quickly.…”
