Cross Sections and Metallography
-
Rocky Mountain Laboratories, Inc.
Cross sections are prepared by mounting samples in epoxy and then grinding and polishing the mount for imaging in the optical microscope or Scanning Electron Microscopy (SEM). Valuable information from cross sectioning can include: film thicknesses, inclusions, corrosion thickness, dimensional verification, and subsurface defects. Metallographic cross sections are typically etched to reveal the microstructure. Microstructural analysis can provide information about heat treatment history, corrosion susceptibility, as well as undesirable microconstituents.

Linear Polarization Resistance (LPR) Monitoring
-
The electrochemical technique, commonly referred to as Linear Polarization Resistance, is the only corrosion monitoring method that allows corrosion rates to be measured directly, in real time. Although limited to electrolytically conducting liquids, the response time and data quality of this technique make it clearly superior, where applicable, to all other forms of corrosion monitoring.

Corrosion Analysis
Resipod
-
Resipod is a fully integrated 4-point Wenner probe, designed to measure the electrical resistivity of concrete in a completely non-destructive test. It is the most accurate instrument available, extremely fast and stable and packaged in a robust, waterproof housing designed to operate in a demanding site environment. The Resipod is the successor of the classic CNS Farnell Resistivity Meter.Surface resistivity measurement provides extremely useful information about the state of a concrete structure. Not only has it been proven to be directly linked to the likelihood of corrosion and the corrosion rate, recent studies have shown that there is a direct correlation between resistivity and chloride diffusion rate and even to determination of early compressive strength. This makes it one of the most versatile NDT methods for concrete.
