At Rocky Mountain Labs, metallurgical analysis is a critical technique for investigating corrosion-related failures and material degradation in metals and alloys. Corrosion can compromise structural integrity, shorten service life, and lead to costly breakdowns in essential components across industries such as aerospace, manufacturing, transportation, energy, and medical devices. Through precise metallurgical examination, we help clients identify corrosion mechanisms, analyze contributing factors, and develop prevention strategies and better material choices.
Why Conduct Metallurgical Examination for Corrosion?
Corrosion is more than a cosmetic or surface-level issue—it involves complex interactions between material properties, environmental conditions, and mechanical stresses. A thorough metallurgical investigation addresses critical questions:
- What type of corrosion occurred? (e.g., pitting, crevice, galvanic, intergranular, stress corrosion cracking)
- What factors contributed to the corrosion failure?
- Was the correct material selected for the environment and application?
- Did fabrication, welding, or heat treatment processes affect corrosion resistance?
By uncovering the microstructure, surface condition, and chemical environment, we deliver evidence-based insights that guide material selection, process improvements, and failure mitigation.
Methods Employed in Corrosion Analysis
To assess corrosion-related damage, Rocky Mountain Labs uses a combination of microscopic, chemical, and mechanical techniques, including:
- Optical and Scanning Electron Microscopy (SEM): Examines corrosion morphology, topography, and microstructural changes.
- Energy Dispersive X-ray Spectroscopy (EDS): Identifies corrosion products and elemental composition of deposits.
- Metallographic Cross-Sectioning: Reveals depth of corrosion attack, intergranular penetration, and structural integrity.
These integrated techniques help determine whether corrosion is due to improper material choice, design issues, processing flaws, or operational stressors.
Common Corrosion Mechanisms Identified
Rocky Mountain Labs provides expert evaluation of various corrosion types, such as:
- Uniform Corrosion: Even material loss over exposed surfaces.
- Pitting Corrosion: Localized, deep cavities, especially in stainless steels and aluminum alloys.
- Galvanic Corrosion: Occurs when dissimilar metals are in electrical contact in a corrosive environment.
- Crevice Corrosion: Found in tight gaps, joints, or shielded areas.
