Liukastamattomissa

Liukastamattomissa is a Finnish term meaning in a non-lubricated state or without lubrication. It is used in technical and scientific writing to describe surfaces, interfaces, or environments where no lubricant is present or applied. The word is formed from the base liukastama related to lubrication, combined with a negating sense and the inessive suffix -issa to denote a state or condition.

In practice, liukastamattomissa distinguishes dry or unlubricated conditions from lubricated ones. It is common in discussions of tribology, material testing, and mechanical design, where friction, wear, and performance can differ significantly depending on lubrication. For example, tests or measurements might be described as conducted liukastamattomissa olosuhteissa to assess baseline wear or friction without the influence of a lubricant, or to compare results with those obtained under lubrication.

The concept is closely related to the broader idea of dry friction, and it is often contrasted with lubricated or oiled conditions to highlight differences in performance. While the English-language equivalent is typically described as “in non-lubricated conditions,” liukastamattomissa is the standard Finnish phrasing used in technical literature.
