- The natural color, that is, there is no treatment on the surface, this situation is easy to rust
2, cold galvanized, this is the most commonly used surface coating for U-shaped bolts, which is characterized by economical benefits and general corrosion resistance
3, Dacromet, moderate corrosion resistance
4, hot-dip galvanizing, this kind of coating has a thicker zinc layer and is characterized by corrosion resistance. This kind of coating is often used in general electric power construction or outdoor construction
5. Multi-alloy co-permeation, which has the advantages of high bonding strength, high coating hardness, no hydrogen embrittlement hazard, good coating thickness uniformity, simple process, and raw material saving.
It has good adhesion, extreme pressure resistance, high and low temperature resistance, and at the same time, it can prevent surface damage and corrosion of the workpiece. The wear-resistant coating is placed on the surface of the Hexagon Socket Head Bolt by a special processing method, and heated and sintered to form a dense and uniform dry film lubricating layer with strong adhesion.
1, improve the torque coefficient of fasteners
Wear-resistant coating can effectively improve the torque coefficient of fasteners. According to customer needs, adjust the torque coefficient to 0.09-0.13 or process fasteners with specific torque coefficients according to customer needs.
2, solved the problem of anti-seize and anti-seize of fasteners
The lubricating coating formed by applying molybdenum disulfide paint on the thread or surface of the fastener, after the fastener is used, it is not easy to rust, seize, and seize.
3, solve the problem of ultra-high temperature and ultra-low temperature lubrication of fasteners
Abrasion-resistant coatings can be made according to the needs of customers' actual working conditions to produce coatings with different temperature requirements of -270°C and 380°C. That is, the surface coating of fasteners at this temperature will not be embrittled and still have lubricating properties.
4. Solve the problem of wear resistance and self-lubrication of fasteners
Based on the excellent performance of EUBO wear-resistant coating materials, the wear-resistant coating has good wear resistance and self-lubricating properties. Fasteners can be loosened and locked repeatedly, the threaded teeth will not be damaged, time and effort are saved, and costs are saved.
5, solve the problem of rust and corrosion of fasteners
The wear-resistant coating forms a dense and firm lubricating film on the surface of the threaded tooth or the surface of the fastener, the film thickness is about 10 microns. The film cuts off the contact between the metal substrate and the air, and it is not easy to cause the substrate to rust. If it is used in conjunction with hot-dip galvanizing or other anti-corrosion coatings, it will have a better anti-rust and anti-corrosion effect.
6, China Stud Supplier solves the problem of maintenance-free fasteners
In some specific environments, the lubrication system of the working environment that cannot be maintained (such as the field environment), is inconvenient to maintain (ultra-high and low temperature, toxic environment, etc.) or the maintenance cost is high, the solid lubrication dry film form can be eliminated maintain.
