Abstract

fetched live from OpenAlex

Abstract Corrosion-related challenges are usually addressed during the detailed engineering phase to meet the specified service life of the asset, but a comprehensive strategy to lower corrosion costs is rarely implemented. A life-cycle cost (LCC) analysis is often used to optimize the design and consider direct and indirect costs. The approach allows to quantify the capital and operating costs and costs associated with the failure of assets and potential implications associated with safety and environmental damage. The present paper explores the cost of corrosion in the mining industry and attempts to identify pathways for design optimization. The current work examines the corrosion costs associated with the lithium processing industry using an LCC analysis. The direct cost of corrosion was determined by quantifying the cost of all corrosion-related activities and design, and the indirect cost of corrosion was estimated through industry-accepted models. The effectiveness of corrosion mitigation strategies was evaluated by examining the sum of present value of money. Net present value of money over the design life of the investment and/or the shortest payback period, and/or the highest return on investment (ROI) were briefly discussed as the alternative approaches for identifying the most economic corrosion control system.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
