Allabrasione

Allabrasione is a term occasionally encountered in Italian-language technical writing to describe a process that subjects all surfaces of a component to an abrasive treatment. It is not a standard term in major glossaries or standards; when used, it typically refers to comprehensive surface preparation or finishing intended to produce uniform roughness, improve cleanliness, or promote coating adhesion across the entire object.

Etymology and scope: The word combines all- (all) and abrasione (abrasion). As a concept, allabrasione is descriptive rather than a formal process name, and its exact meaning can vary by context.

Process and methods: Depending on material and tolerances, allabrasione might involve mechanical techniques such as sanding, grinding, bead blasting or shot peening, and sometimes combined chemical or enzymatic steps. The aim is to achieve controlled material removal and surface texture on every exposed area. Practitioners specify target surface roughness (for example Ra) and use appropriate media, exposure time, and masking to protect features not intended for abrasion.

Applications and limits: The approach is used as a preparatory step before coatings, adhesives, or composite bonding, or in refurbishment where uniform surface energy is desired. Because it covers all surfaces, there is a heightened risk of dimensional change, over-processing, or creating burrs, and the method can generate waste and particulates.

Standards and safety: In formal manufacturing settings, professionals rely on established surface-preparation standards rather than informal terms. Appropriate personal protective equipment, dust control, and equipment safeguards are essential.
