tühimaht

Usage examples

Pinnaprofiili tühimaht viitab pinnatekstuuride sees olevale tühjale ruumile, mis arvutatakse materjalisuhte kõveralt, et hinnata vedelikupeetust, määrimisvõimet või kulumist. Tavaliselt väljendatakse tühimahtu mahuühikutes pindala kohta, nt µm3/µm2 või lihtsalt µm, ja see jaotatakse oru tühimahuks Vvv ja südamiku tühimahuks Vvc, kusjuures 10 % ja 80 % materjalisuhteid kasutatakse sageli vaikepiiridena.

void volume

Usage examples

Void volume of the surface profile refers to the empty space within surface textures, calculated from the material ratio curve to quantify fluid retention, lubrication capability, or wear potential. It is typically expressed in units of volume per area (e.g., µm3/µm2 or simply µm) and is separated into dale (Vvv) and core (Vvc) void volumes, with 10 % and 80 % material ratios often used as default boundaries.
