Passivoidaan

Passivoidaan is the present passive form of the Finnish verb passivoida. In Finnish grammar it denotes that a subject is being passivated or made non-reactive, with the agent often omitted or expressed with a by-phrase. The form is commonly used in technical contexts to describe an ongoing process or a general statement about passivation.

In science and engineering, passivoituminen refers to rendering a surface or material chemically inert and resistant to corrosion. This is achieved by forming protective layers, such as oxide films, or by applying coatings and treatments that reduce reactivity. Passivointi is a standard concept in metallurgy, chemistry, and materials science, with stainless steel, aluminum, and other metals frequently undergoing passivation to improve longevity and performance. Typical formulations include statements like “teräsrakenteet passivoidaan hapettumiselta” or “passivointi vähentää korroosiota.”

In linguistics and grammar, passivoidaan describes the process of converting an active sentence into the passive voice. Finnish uses the passive form to shift focus from the actor to the action or the recipient of the action. For example, an active sentence like “ Tutkija tarkistaa laitteen” can be expressed in the passive as “Laitetta tarkistetaan tutkijan toimesta,” illustrating how the subject matter changes while the action remains.

Kurz, passivoidaan is a versatile term reflecting both a chemical/technical process and a grammatical transformation, with the exact meaning clarified by domain and context. See also passivointi.
