lemezés

Lemezés is a Hungarian term that translates to "plating" or "coating" in English. It refers to the process of applying a thin layer of one material onto the surface of another, typically a metal. This is done for various reasons, including protection against corrosion, improving appearance, enhancing conductivity, or increasing wear resistance. The most common method of lemezés is electroplating, where an electric current is used to deposit ions of the coating metal onto the substrate in an electrolyte solution. Other methods include hot-dip coating, chemical vapor deposition, and physical vapor deposition.

Different metals are used for lemezés depending on the desired properties. For example, zinc is often used for its anti-corrosive properties on steel, a process known as galvanizing. Chromium plating is employed for its hardness, durability, and decorative appeal, frequently seen on automotive parts and bathroom fixtures. Nickel plating offers good corrosion resistance and wear resistance. Gold and silver plating are used for both aesthetic and conductive purposes. The thickness of the deposited layer can vary significantly, from a few micrometers for decorative purposes to several millimeters for functional applications.

The lemezés process requires careful control of parameters such as current density, temperature, and electrolyte composition to ensure a uniform and adherent coating. The surface of the object to be plated must also be thoroughly cleaned and prepared to remove any grease, dirt, or oxides that could interfere with the adhesion of the coating. Lemezés is a widely used industrial process across many sectors, including automotive, electronics, jewelry, and construction, contributing to the longevity and performance of countless products.
