Causes and Prevention Methods of Equipment Corrosion and Wear

I. Primary Causes of Corrosion Wear

Chemical Corrosion

Metals undergo redox reactions with corrosive media (acids, alkalis, salts, etc.), leading to the destruction of surface oxide films. For example:

Acid corrosion accelerates the corrosion cycle by forming soluble metal salts through displacement reactions.

Localized damage to passivation films triggers pitting corrosion, forming deep, narrow, or elliptical pits.

Electrochemical Corrosion

Contact corrosion occurs between dissimilar metals, or localized cathodic regions cause metal ion loss.

Environmental Factors

High temperatures (≤500°C) accelerate oxidation reactions, while low temperatures (below -40°C) induce metal embrittlement.

Moisture and salt spray promote electrolyte formation, intensifying electrochemical corrosion.

Synergistic Mechanical Wear

Friction surfaces experience material spalling due to the combined effects of the adhesion theory (instantaneous temperatures reaching 1000°C) and molecular mechanical theory (mechanical interlocking + disruption of molecular forces).

II. Protection Methods

Material Protection Technologies

Coating Protective Layers:

Non-metallic layers (enamel, fiberglass) resist acid/alkali penetration for ≥60 minutes

Metal coatings (nickel, chromium, zinc) form dense barriers via electroplating

Alloying Treatments: Add chromium, nickel, or other elements to enhance corrosion resistance

Environmental Control

Add corrosion inhibitors (inorganic chromates or organic nitrogen/sulfur compounds) to suppress corrosion reactions

Use desiccants or chemical deoxidizers (e.g., sodium sulfite) to reduce medium activity

Electrochemical Protection

Cathodic protection (sacrificial anodes: zinc/magnesium alloys)

Anodic protection (electrolytic passivation of metal surfaces in strong acid environments)

Maintenance Management

Regular coolant replacement (avoid mixing aluminum-based coolants with water)

Application of wear-resistant coatings (tungsten carbide layers reduce wear rates by 5-8 times)

Intelligent monitoring systems provide real-time alerts for corrosion and wear conditions

III. Typical Applications

Wind turbines: Graphene self-healing coatings form ultra-hard metal-ceramic layers to reduce friction coefficients

Chemical pipelines: Ceramic-metal composite layers withstand 200°C organic solvent corrosion

These measures significantly extend equipment lifespan. We recommend selecting protective solutions tailored to specific operating conditions.
