passzíválás

Passzíválás is a Hungarian term that refers to the process of rendering something inactive or inert, often to prevent unwanted reactions or to ensure safety. This can apply to various contexts, including industrial processes, chemical reactions, or even the deactivation of devices.

In chemistry, passzíválás typically involves coating a reactive surface with a protective layer that prevents further chemical attack. For example, certain metals can be passivated to resist corrosion by forming a thin, stable oxide film on their surface. This film acts as a barrier, preventing corrosive agents from reaching the underlying metal. Stainless steel is a common example where passivation occurs naturally due to chromium oxide formation.

Industrially, passzíválás is used to make materials safer to handle, transport, or store. This might involve deactivating hazardous chemicals or neutralizing explosive substances. For instance, explosives can be "desensitized" through chemical treatment to reduce their sensitivity to shock or friction.

The term can also be used in a more general sense to describe making something less active or less likely to cause trouble. In a technological context, it could refer to disabling a function or a device to prevent its operation. The core concept remains the same: to reduce or eliminate an inherent potential for activity or reaction. The specific method and purpose of passzíválás depend heavily on the material or system being treated.
