System for plasma surface activation

The device is designed to activate surfaces with low-pressure oxygen plasma. The essential part of the system is a vacuum chamber, enabling the introduction of a steel basket that can be rotated during the plasma plating process. The rotation ensures even activation of the entire surface of details made of steel or plastic placed in the basket. The chamber was designed in a way that allows for expansion with a water cooling system. The system is equipped with a dry pump to obtain the desired pressure, a pressure gauge allowing measurement regardless of the gas composition inside the chamber, and a gas dosing and plasma generation system.

Control of the system operation, including the maximum time of pumping out the chamber, pressure during the process, and chamber rotation parameters, is carried out using a controller, enabling the selection of an appropriate activation program.

The interaction of plasma with processed details leads to surface modification, especially in its structure and physicochemical properties. The cause of these phenomena is the high reactivity of the ionized gas. For this reason, plasma is used, among others, for surface cleaning, surface activation, changing hydrophobicity, and sterilization by killing microorganisms. Plasma treatment is a clean technology that allows for limiting the formation of contaminants by excluding the use of chemicals.
