Our testing equipment includes the following state-of-the-art equipment:
Electrochemical corrosion testing helps prevent harmful interactions between various metals and the environment. SFTec provides non-destructive and non-perturbative electrochemical techniques for corrosion testing, whose main advantages include:
Since a wide number of factors may affect corrosion behaviour and corrosion resistance, there is no universal corrosion test. But you can rely on our experience in corrosion testing. All our services are under most relevant and applicable standards, including
Electrochemical Corrosion test methods
LPR is a quick and non–destructive electrochemical method, providing useful and reliable corrosion rate date.
In these method (ASTM G5, G59, G61), the potential is swept in a small range around the open–circuit potential, and the resulting current of the tested system is measured. The polarization resistance is represented by the slope of applied potential and the resulting current, following the Ohm’s law. The method provides two significant parameters over testing time, which cannot be obtained with standard EIS method:
Galvanic corrosion occurs when two or more dissimilar metals (electrodes) are in electrical contact in the presence of a common corrosive electrolyte (e.g. seawater). When a galvanic couple forms, the less resistant material becomes the anode and the more resistant the cathode. The cathodic material corrodes slower than normal or not at all, while the corrosion of the anodic material is greatly enhanced.
SFTec provides galvanic corrosion tests in accordance with industry standards or client-specific standards for evaluating the behavior of metals and metallic coatings in accelerated corrosion environments.
Our corrosion testing laboratories carry out galvanic corrosion testing on combinations of metals and metallic coatings to evaluate the damage due to galvanic corrosion.
SFTec also perform specific electrochemical corrosion testing analysis to evaluate galvanic corrosion performance of two or more dissimilar metals when electrically connected in a selected environment using three main test categories:
Corrosion susceptibility can be assessed by a wide range of methods, with electrochemical impedance spectroscopy being of particular interest as it provides fast and accurate performance data.
SFTec performs electrochemical impedance spectroscopy (EIS) tests according to ISO 16773, or other customer standards.
Characterization of cured coatings is used to test the suitability of the material selected/used in a project or to perform failure investigations through chemical and physical property testing. Coating testing and analysis are also very helpful to support the development of new formulations.
In our lab, we can perform the following tests:
SFTec offers an entire portfolio of physical testing, including standard test methods (ASTM, ISO) to help understand the coating’s durability and performance, including coating thickness, density, hardness, scratch resistance, adhesion property testing, opacity, and thermal and rheological properties.
Spectroscopic techniques such as Fourier transform infrared spectroscopy (FTIR spectroscopy) or Raman spectroscopy provide chemical screening and identification of components. When used in product deformulation studies the data can help you to understand the competitor formulation and the raw materials used.
Our analytical and polymer scientists perform chemical analysis of coating formulations delivering valuable information to support either formulation development or competion product analysis.
SFTec battery testing laboratory features state-of-the-art equipment for the performance analysis of battery materials, cells or battery packs. We are capable of handling multiple charge/discharge tests and electrochemical characterization techniques (including EIS) at the same time.
Some available tests are:
Extensive baterry testing capabilities with mutichannel equipment:
SFTec laboratory is located in the Technologic and Cientific Park of the University of Las Palmas de Gran Canaria, in the canary islands, with access to natural sea-water and Oceanic Platform of the Canary Islands (PLOCAN) . Here our coating-experts could perform a wide range of multidisciplinary experiments under real marine environmental conditions and exposure regimes.
