Trošenje

U nauci o materijalima, trošenje je erozija materijala čvršte površine drugim čvrstim predmetom. Proučavanje procesa trošenja je dio discipline koja se naziva tribologija.

Postoje četiri glavna procesa trošenja:

1. Adhezivno trošenje
2. Abrazivno trošenje
3. Korozivno trošenje
4. Zamor površine

Adhezijsko trošenje

Adhesive wear is also known as scoring, galling, or seizing. It occurs when two solid surfaces slide over one another under pressure. Surface projections, or asperities, are plastically deformed and eventually welded together by the high local pressure. As sliding continues, these bonds are broken, producing cavities on the surface, projections on the second surface, and frequently tiny, abrasive particles, all of which contribute to future wear of surfaces.

Abrazivno trošenje

When material is removed by contact with hard particles, abrasive wear occurs. The particles either may be present at the surface of a second material or may exist as loose particles between two surfaces. Abrasive wear can be measured as loss of mass by the Taber Abrasion Test according to ISO 9352 or ASTM D 1044.

Korozivno trošenje

Šablon:GlavniKorozija Korozivno trošenje (često se naziva samo "korozija") je slabljenje korisnih osobina materijala zbog reakcija sa okolinom.

Zamor površne

Glavni članak: Zamor (materijal)

Zamor površine je proces u kome je površina materijala oslabljena cikličnim teretom, što je jedna vrsta općeg zamora materijala.
