Lerakási

Lerakási is the Hungarian noun form that refers to the act or process of laying down, placing, or depositing material. It covers both natural processes, such as sedimentation, and human-made processes, such as applying coatings or films. The word is derived from the verb lerakni, meaning “to lay down,” with the noun-forming suffix -ás, and it is used in various technical and everyday contexts to describe emplacement or layering.

In geology and earth science, lerakás denotes the deposition of sediment, minerals, or organic matter from air, water, or ice. This process builds up stratified layers that reveal the history of a landscape and is analyzed in sedimentology and stratigraphy to interpret past environments and geological time.

In materials science and industry, lerakás refers to the formation of thin films or coatings on a surface. This includes processes such as electrochemical deposition (electrodeposition), chemical vapor deposition, and physical vapor deposition. Control over thickness, uniformity, and composition of the deposited layer determines the properties of the finished product, such as hardness, corrosion resistance, or electrical conductivity.

In archaeology and cultural contexts, lerakás can describe the deliberate placement or deposition of objects within a site, which may reflect ritual practices, daily activities, or construction sequences. The term also appears in other practical domains to describe the act of placing items in a specific order or arrangement.
