Korrosioonina

Korrosioonina is a Finnish term that literally translates to “as corrosion.” In technical and industrial contexts it is used to describe processes, conditions, or substances that function as additional sources of corrosion or that accelerate the corrosion of metallic components. The concept is often employed in engineering documentation, maintenance reports, and environmental compliance assessments to highlight factors that contribute to the degradation of metal surfaces.

In practice, substances such as chloride ions, acidic vapors, or highly humid atmospheres are identified as korrosioonina when they are present in concentrations that exceed the protective thresholds of corrosion‑resistant coatings or alloys. The term also applies to mechanical stresses or electrochemical configurations that make a metal more susceptible to pitting, galvanic action, or crevice corrosion. By explicitly labeling these factors as korrosioonina, engineers can prioritize mitigation measures, select appropriate materials, and justify the implementation of cathodic protection or sacrificial anode systems.

Korrosioonina awareness is integral to life‑cycle cost analysis of pipelines, storage tanks, and structural steel. It informs inspection schedules and statistical models that predict metal loss over time. Regulatory bodies in Finland may require documentation of identified korrosioonina factors as part of permits for construction projects involving steel or other metals that will be exposed to harsh environments. This focus on identifying and documenting corrosion drivers is a key pillar of preventive maintenance and sustainable materials management.
