Abstract: A method of visually investigating a coated surface of an object, the coating comprising a metal or an alloy, in order to determine whether or not the coating is tight. An increasing potential is applied to the object until a desired current level has been obtained or until a maximum potential has been reached. In case the coating is tight this results in a change in colour of the coating. This may be due to a polarization of the coating material and/or due to an increase in thickness of a naturally occurring metal oxide layer. In case the coating is tight the desired current level can not be obtained, and the potential is increased to the maximum level resulting in a change in colour. In case pinholes are present it is possible to obtain the desired current level, and the increase in potential is stopped before it is high enough to cause the change in colour. Provides a dramatic visual effect allowing an immediate determination of whether or not pinholes are present. Need for additional equipment for determining the presence of pinholes is avoided. In case the coating material is or comprises tantalum or an alloy of tantalum, the colour is changed into a distinct blue colour.

Abstract: A method of measuring localized corrosion, using a multi-electrode array sensor. The method eliminates the effect of internal current in corroded electrodes, and thus provides a more accurate corrosion measurement. In one embodiment, the potential of a common node of the sensor is adjusted so that the sensor’s most cathodic current is close to zero.

Abstract: The chloride corrosion threshold of a metal embedded (11) in a cementitious structure (14) is determined in an accelerated manner by using an electric field (41, 42) to increase the rate of migration of chloride ion into the structure (14) and monitoring the interface between the metal (11) and the cementitious material (26) in structure (14) to detect the onset of corrosion, then determining the chloride corrosion threshold, which is defined as the chloride content of the cementitious material (26) once corrosion has begun. This determination can be performed over a time period of as little as 2 to 3 weeks rather than the months or years required by conventional chloride corrosion test procedures.

Abstract: This invention describes a novel means of determining the nature (type) of corrosion in real-time. By identifying localized corrosion at the moment of pit initiation, real-time selection, and effective concentration(s) of approriate inhibitor(s) can be delivered to an electrolytic solution before propagation of the localized corrosion. Integrating this information with a corrosion inhibitor feed system can effectively inhibit the corrosion before propagation occurs, thereby maintaining system integrity. The process embodies a method of operation wherein the electrochemical noise (ECN) and linear polarization (LPR) values are processed to compare how the corrosion signals correlate. Divergence of the corrosion rates indicates the formation of localized corrosion while continuity in signal pattern indicates generalized corrosion.

Abstract: A system for monitoring the material changes in a structure through the use of monitoring instruments (40) is shown in Figure 1. The instruments (40) have at least one sensor (16, 48, 50, 160) with electrodes (42, 44, 52, 56) in contact with the surrounding materials and electronics that are contained within the instrument. The sensor signals are converted to digital and transmitted to an external data logger or computer for display of the signals. The connection between the microcontroller (30) and the data logger can be either through hardwire (6) or RF. Power is provided to the electronic sensors through either external or local methods. A power management system (16) can be used to place the electronics in sleep mode when not in use. The electronics are encapsulated within potting material within an instrument case (600) that is manufactured from a material having a flexural modulus equal to, or greater than, the surrounding material to prevent mechanical failure of the device before failure of the surrounding material. The case has protective trays (540, 560) to protect the electrodes and rounded adjacent connection lengths to prevent the case from developing cracks.

Abstract: A method of determining the fatigue status of a metal-containing specimen (19), where the method utilized is benign to the fatigue properties of the tested specimen, in spite of the presence of an electrolyte (15), and the claimed method and the Electrochemical Fatigue Sensor (EFS) (10) device applying the claimed method can measure fatigue damage at different points during the service life of a metallic structure. The tested specimen is placed in an EFS cell containing an electrode (12) and an electrolyte, which does not cause any degradative effects to the tested specimen and is in contact with the tested specimen. The electrolyte is used with EFS device and method of the invention is capable of being incorporated in a gelling material. A voltage is then applied, or galvanically created, between the specimen and the electrode, and the current is measured passing through the electrolyte during a period in which the specimen is subjected to cyclic stresses. By analyzing the elastic and plastic deformation transient current components the fatigue status and remaining fatigue life of a specimen are determined and/or estimated.
