surface treatment
Surface treatment refers to the process of changing or enhancing the properties of material surfaces. Various methods such as cleaning, polishing, coating or etching can be used for this.
The goal of surface treatment may be to improve corrosion resistance, durability, lubricity, aesthetics, or other properties. Depending on the type of material surface and the desired properties, different surface treatment techniques can be used.
It is important that the treatment is carried out precisely and with care in order to achieve the best possible result.
