Slitageskador

Slitageskador is a term used in technical contexts to describe damage resulting from wear in materials exposed to repeated contact, friction, and loading. It encompasses progressive deterioration rather than sudden failure, and is a concern in machinery, infrastructure, and components.

Etymology: The word is formed from Swedish slitage meaning wear and skador meaning damages. It has occasional use in Nordic engineering literature and some translated works.

Characteristics: Slitageskador manifests as surface degradation such as micro-scratching, scoring, pitting, and increasing roughness, leading to reduced dimensional accuracy, efficiency, and increased heat. It arises from mechanisms including abrasive wear, adhesive wear, and fatigue under cyclic loads, especially with insufficient lubrication, misalignment, or contamination.

Assessment and mitigation: Detection relies on visual inspection, profilometry, wear rate calculations, and non-destructive testing. Maintenance strategies focus on lubrication optimization, material selection, coatings, alignment, and design changes to reduce contact stress. Predictive maintenance uses wear models and sensor data to estimate remaining useful life.

Relationship to related concepts: It is related to wear, tribology, material fatigue, and corrosion. It is distinct from sudden accidental damage, though interactions exist. The term is not internationally standardized and is sometimes used loosely in industry; readers should consult local terminology.
