Corrosion Testing and Corrosion Monitoring

WebCorr has NACE certified Corrosion Specialist providing corrosion advisory services, corrosion diagnosis, corrosion testing and corrosion monitoring, in-house training, online and distance learning corrosion courses, corrosion consulting, corrosion failure analysis and corrosion expert witness in litigation and arbitration cases related to corrosion, materials, metallurgy, paints & metallic coatings including thermal spray metallizing, galvanizing, anodizing, chromating, phosphating, electroplating, electroless plating, mechanical plating, and sheradizing or diffusion coating.

In addition to Corrosion Literature Search & Supply (CLSS), our NACE certified corrosion specialist can also provide corrosion testing and monitoring services in accordance with international standards such as ASTM, ISO, BSI, DIN, JIS, NACE and SIS. Our capability covers both DC polarizationtechniques and AC impedance measurements and EIS equivalent circuit modeling with popular softwares such as Boukamp's Equivcirt, Scribner's ZView & CorrView and Mansfield's EIS Modules. Our NACE certified corrosion specialist will analyze the raw (or processed) corrosion data, write and sign the technical report. Expert witness and litigation support are also available if required.

Verification or Certification Test: Verification of whether materials or products have been produced in accordance with the relevant international standards or to contract specifications may be established by corrosion test. WebCorr has access to a wide range of equipment and expert personnel for testing physical, mechanical and corrosion resistance properties of materials.

DC and AC (EIS) Corrosion Testing & Monitoring techniques can be used for the following applications:

• Corrosion rate determination

• Life prediction of components and structures

• Materials selection and evaluation

• Anode testing and selection

• Assessment of the corrosiveness of an environment or process

• Corrosion inhibitor screening (determination of inhibiting efficiency)

• Protective property of polymeric paint (organic coatings) and composite

• Quality control and performance evaluation of electroplating, electroless plating, galvanizing, anodizing, chromating, and phosphating treatments

• Determining susceptibility of a material to pitting, crevice and sensitization or intergranular stress corrosion cracking

• Optimization of processing parameters (temperature, pH, flow rate etc.) to minimize corrosion

• Online or offline monitoring of corrosion

• Trouble shooting and failure investigation

More application examples are given in the corrosion short course on "Corrosion Testing and Monitoring Made Easy: Techniques and Applications".
