How Decay & Rust Calculation Works

Material Science

Based on electrochemical corrosion principles and material degradation rates under different environmental conditions.

Environmental Factors

Considers humidity, temperature, salt exposure, pollution levels, and their combined effect on corrosion rates.

Protection Methods

Calculates effectiveness of various protection methods including coatings, galvanization, and cathodic protection.

Time Projection

Projects material loss over time and estimates remaining useful lifespan based on current decay rates.

Risk Assessment

Identifies critical stages of corrosion and provides warnings for structural integrity concerns.

Maintenance Planning

Suggests optimal maintenance schedules and protection methods based on calculated decay rates.

Common Applications

Construction

Calculate steel structure lifespan, reinforcement corrosion rates, and building material durability.

Marine

Estimate hull corrosion in saltwater, calculate sacrificial anode requirements, and plan maintenance.

Automotive

Calculate vehicle body corrosion, estimate chassis lifespan, and plan rust prevention treatments.

Oil & Gas

Calculate pipeline corrosion rates, estimate equipment lifespan, and plan corrosion monitoring.

Home Maintenance

Estimate roof material decay, calculate fence post rust rates, and plan home protection schedules.

Infrastructure

Calculate bridge corrosion rates, estimate rebar degradation, and plan infrastructure maintenance.
