Top surface treatment of binding material
| Process | Process description |
|---|---|
| Bluing | Bluing is a chemical process at a temperature of about 140°C, followed by immersion in oil, also known as hot bluing. It is a common method of coloring steel products. This process leads to a chemical reaction during which a black-bluish oxide layer is formed on the surface of the material. The black coating mainly has a decorative character, but also serves to enhance the corrosion resistance of materials (mild protection). |
| DELTA-MKS Delta-Seal Delta-Tone Delta-Protekt |
Special surface treatment of the material carried out by applying protective coatings to the material, followed by "drying" in a furnace. Protective coatings contain no heavy metals and have no carcinogenic and mutagenic effects. They are distinguished by high corrosion resistance, excellent chemical and thermal resistance with the possibility of forming a non-conductive coating while preventing formation of contact corrosion. Option to select the color design from a wide variety of colors. |
| Nickel coating | Serves both as a decoration and as a protection against corrosion. Thanks to a hard layer it finds application in the manufacture of electric devices in telecommunications. Especially in the case of screws, the abrasion of the surface layer doesn't occur. Nickel-plated pieces of iron are not recommended for outdoor use. |
| Galvanic zinc coating | Galvanic zinc coating is electrodeposition of a thin zinc layer on conductive material such as steel, alloy, brass, copper. This increases the resistance of the material surface against corrosion, hardness, electrical conductivity, and the like. Thanks to chromatization, the surface gains a silver or golden afterglow, while also improving the layer's resistance. |
| Mechanical galvanizing | Chemical-mechanical process of layering. Degreased parts are placed in a plating drum together with a special mixture of glass beads and zinc powder. The glass beads act as a carrier of zinc powder grains, and are deposited on the surface of the material which the beads are adhered to due to cold sealing. |
| Hot-dip galvanized | During hot-dip galvanizing, steel is immersed in 450°C hot zinc melt after suitable preparation. Zinc and steel react with one another. An alloy of iron and zinc is formed on the steel surface. This non-detachable connection of zinc and steel give protection, which differs significantly from the other processes. Surfaces treated by hot-dip galvanizing are protected against the influence of wind and weather for decades and also possess a good resistance to mechanical influences. |
| Heat treatment | Heat treatment is a technological process where the material is heated and cooled to thus its properties such as strength, hardness, toughness, machinability, and wear resistance are altered. The desired adjustment of properties is achieved by annealing, quenching, tempering, refinement (in oil or in water) and a chemical-thermal treatment (cementation). |
Surface finish referred to in the list is among the most common surface treatment processes of bonding material. For specifics on other method of surface treatment or additional information, please contact our sales division.
