Welcome to CogentLab
At CogentLab, we offer a comprehensive range of analyses to effectively manage and mitigate corrosion in your components. Our services include:
Salt Spray Test (ASTM B117)
• Purpose: To assess the corrosion resistance of coated or bare metals.
• Application: Commonly used for coatings, paints, and metals in marine environments.
EIS
• Purpose: To evaluate the resistance of coatings and passivation layers.
• Application: Used for evaluating protective coatings, films, or studying passivation behavior.
Potentiodynamic Polarization (Tafel Test)
• Purpose: To determine the corrosion rate and evaluate anodic and cathodic behaviors.
• Application: Used for metals to determine corrosion rates and passivation.
Immersion Test
• Purpose: To simulate real-world exposure of metals in corrosive environments.
• Application: Used for determining general corrosion resistance of metals in industrial environments.
Cyclic Potentiodynamic Polarization (CPP)
• Purpose: To evaluate pitting or crevice corrosion susceptibility.
• Application: Typically used for stainless steels and other passive materials.
Linear Polarization Resistance (LPR)
• Purpose: To determine the corrosion rate in real-time.
• Application: Often used for rapid monitoring of corrosion rate in pipelines and coatings.
Gravimetric Weight Loss Test
• Purpose: To determine the amount of corrosion that has occurred over a specific period.
• Application: Used for general corrosion resistance assessment of metals in various environments.
Intergranular Corrosion Test (ASTM A262)
• Purpose: To determine susceptibility to intergranular attack, especially in stainless steels.
• Application: Useful for stainless steels to evaluate grain boundary stability.
Cyclic Corrosion Testing (CCT)
• Purpose: To simulate the real-world fluctuating conditions of wet and dry exposure.
• Application: Often used in automotive and outdoor equipment industries to simulate environmental changes.
Stress Corrosion Cracking (SCC) Test
• Purpose: To determine susceptibility to cracking under tensile stress in corrosive environments.
• Application: Used for stainless steels, aluminum alloys, and high-strength steels.
Crevice Corrosion Test
• Purpose: To evaluate the susceptibility to crevice corrosion in confined spaces.
• Application: Especially important for stainless steels and nickel alloys.
Pitting Corrosion Test (ASTM G48)
• Purpose: To assess pitting resistance.
• Application: Often used for stainless steels to evaluate resistance to localized attack.
Atmospheric Corrosion Testing
• Purpose: To evaluate material performance under natural outdoor conditions.
• Application: Evaluates the long-term effects of exposure to atmospheric pollutants and varying weather.
Hydrogen Embrittlement Test (ASTM F519)
• Purpose: To determine susceptibility to hydrogen embrittlement.
• Application: Typically used for high-strength steels and materials used in harsh environments like oil and gas.
Corrosion Fatigue Test
• Purpose: To evaluate the effect of cyclic loading in a corrosive environment.
• Application: Used for components subjected to both mechanical stress and a corrosive environment.
Cathodic Protection Efficiency Test (NACE SP0169)
• Purpose: To evaluate the effectiveness of a cathodic protection (CP) system in preventing corrosion of metallic structures.
• Application: Commonly used for pipelines, storage tanks, marine structures, and other buried or submerged metallic infrastructure to ensure adequate corrosion prevention by the CP system.
