Corrosion Behavior and Inhibition
Research Guide
What is Corrosion Behavior and Inhibition?
Corrosion behavior and inhibition refers to the study of degradation processes in metals due to chemical or electrochemical reactions with their environment and the methods used to mitigate such degradation using inhibitors.
Over 120,102 works have been published on corrosion behavior and inhibition. Song and Atrens (1999) in "Corrosion Mechanisms of Magnesium Alloys" reviewed corrosion mechanisms limiting magnesium alloy use in transport and aerospace despite their high strength-to-weight ratio. Atkinson et al. (1982) in "A quantitative demonstration of the grain boundary diffusion mechanism for the oxidation of metals" showed that below 1000°C, nickel oxidation rates exceed bulk lattice diffusion predictions by orders of magnitude due to grain boundary diffusion.
Research Sub-Topics
Magnesium Alloy Corrosion Mechanisms
This sub-topic investigates degradation pathways, pitting, and filiform corrosion in Mg alloys for biomedical and automotive uses. Researchers model hydrogen evolution and chloride-induced breakdown using electrochemistry.
Organic Corrosion Inhibitors
This sub-topic examines adsorption behavior, film formation, and synergism of plant extracts and synthetic molecules on steel. Researchers use EIS, XPS, and DFT to quantify inhibition efficiency in acidic media.
Grain Boundary Corrosion
This sub-topic analyzes intergranular attack, sensitization, and diffusion-controlled oxidation in alloys. Researchers apply electron microscopy and statistical models to predict boundary susceptibility.
XPS Analysis of Corrosion Films
This sub-topic focuses on surface speciation, oxide/hydroxide quantification, and depth profiling of passivated metals. Researchers develop sensitivity factors and deconvolution methods for transition metals.
Electronegativity and Corrosion Hardness
This sub-topic applies absolute electronegativity and chemical hardness to predict metal reactivity and inhibitor design. Researchers correlate Pearson concepts with experimental corrosion potentials.
Why It Matters
Corrosion behavior and inhibition directly impacts industries like transport, aerospace, oil and gas, and acidizing processes where metal degradation causes failures and economic losses. Song and Atrens (1999) in "Corrosion Mechanisms of Magnesium Alloys" identified poor corrosion resistance as the primary barrier preventing wider adoption of magnesium alloys, which offer high strength-to-weight ratios ideal for lightweight structures in vehicles and aircraft. Recent preprints demonstrate practical applications: a systematic review of 45 studies (2018–2025) evaluates green and nano-based inhibitors for mild steel in acidic media used in industrial processes, while ethanolic extracts from agro-industrial wastes inhibit mild steel corrosion in 15% HCl at 30–60°C under oilfield acidizing conditions. A synthesized pyrazolyl-N-acetylthiocarbohydrazone (PTH) provides efficient inhibition for carbon steel in 1.0 M HCl, addressing aggressive acidic environments in petrochemical operations.
Reading Guide
Where to Start
"Corrosion Mechanisms of Magnesium Alloys" by Song and Atrens (1999) provides a foundational review of key mechanisms with clear explanations of galvanic and stress corrosion relevant to engineering applications.
Key Papers Explained
Song and Atrens (1999) in "Corrosion Mechanisms of Magnesium Alloys" establishes core mechanisms for lightweight alloys, which Biesinger et al. (2010) in "Resolving surface chemical states in XPS analysis of first row transition metals, oxides and hydroxides: Sc, Ti, V, Cu and Zn" complements through XPS techniques for surface oxide characterization. Atkinson et al. (1982) in "A quantitative demonstration of the grain boundary diffusion mechanism for the oxidation of metals" quantifies diffusion pathways controlling oxidation rates, building on these by explaining faster-than-expected kinetics. Wagner et al. (1981) in "Empirical atomic sensitivity factors for quantitative analysis by electron spectroscopy for chemical analysis" supplies sensitivity factors essential for quantifying compositions from the XPS data.

Advanced Directions
Recent preprints focus on green inhibitors like pyrazolyl-N-acetylthiocarbohydrazone (PTH) for carbon steel in 1.0 M HCl and Tinospora cordifolia fractions in seawater, evaluated via electrochemical impedance spectroscopy and computational methods. Systematic reviews cover 45 studies on nano-based strategies for mild steel in acidic media.

Frequently Asked Questions
What are the main corrosion mechanisms of magnesium alloys?
Magnesium alloys suffer from poor corrosion resistance due to mechanisms including galvanic, intergranular, crevice, and stress corrosion cracking. Song and Atrens (1999) in "Corrosion Mechanisms of Magnesium Alloys" detail these processes, noting their high strength-to-weight ratio makes them attractive for transport and aerospace despite corrosion issues. This limits their popularity compared to aluminum alloys.
How does grain boundary diffusion affect metal oxidation?
Grain boundary diffusion enables oxidation rates several orders of magnitude faster than bulk lattice diffusion predictions below 1000°C. Atkinson et al. (1982) in "A quantitative demonstration of the grain boundary diffusion mechanism for the oxidation of metals" quantitatively demonstrated this for nickel oxidation through short-circuit paths in oxide grain boundaries. Measured rates match this mechanism precisely.
What techniques analyze surface chemical states in corrosion studies?
XPS analysis resolves surface chemical states of first row transition metals, oxides, and hydroxides like Sc, Ti, V, Cu, and Zn. Biesinger et al. (2010) in "Resolving surface chemical states in XPS analysis of first row transition metals, oxides and hydroxides: Sc, Ti, V, Cu and Zn" provide methods for accurate peak fitting in corrosion surface characterization. These enable quantitative assessment of oxide layers formed during corrosion.
What are examples of green corrosion inhibitors for acidic media?
Eco-friendly inhibitors from ethanolic extracts of agro-industrial and botanical wastes protect mild steel in 15% HCl under oilfield acidizing at 30–60°C. A systematic review synthesizes 45 studies (2018–2025) on green and nano-based strategies for mild steel in acidic media. Synthesized pyrazolyl-N-acetylthiocarbohydrazone (PTH) efficiently inhibits carbon steel in 1.0 M HCl.
How is quantitative analysis performed in electron spectroscopy for corrosion?
Empirical atomic sensitivity factors from 135 compounds of 62 elements enable quantitative analysis by electron spectroscopy for chemical analysis. Wagner et al. (1981) in "Empirical atomic sensitivity factors for quantitative analysis by electron spectroscopy for chemical analysis" developed these factors based on spectral intensity ratios. They support precise compositional analysis of corrosion products.
