Products Details
The anodizing process of black titanium bolts
The process of anodizing involves creating an interference oxidation coating on the titanium's surface. The color of the film is bright and symmetrical, which improves the decorative and artistic value of titanium. Black titanium bolts are widely used as titanium bike bolts, bicycle headset screws, titanium stem bolts, titanium motorcycle bolts, Porsche titanium lug bolts, and BMW titanium lug bolts.
It is to use titanium as the anode, stainless steel or titanium, and other metal materials as the cathode, relying on a certain acidic or alkaline electrolyte solution to promote the electrochemical process that coats the surface of the metal with titanium oxide. This oxide film itself is colorless and transparent and has strong reflection and refraction of light. Since only tens, hundreds, or even tens of naturally occurring titanium oxide films may be generated on a surface through anodic oxidation, the naturally occurring titanium oxide film lacks color. The titanium oxide film in M, which is not the same thickness, exhibits various colors through light interference, and since titanium oxide produces color without the addition of additional ingredients, it is more dependable and secure. Titanium oxide film can improve the wear resistance and corrosion resistance of titanium matrix. It is extensively employed in a variety of fields, including engineering, aviation, and medicine.

Degrease
Degreasing is to better remove the grease, oxide scale, and large defects left on the titanium surface after machining. To set the stage for further colorless spots, expose the clean, freshly polished titanium surface.
Pickling
The purpose of pickling is to expose the surface of fresh titanium substrate and to produce firm and stable titanium oxide film without color spots after anodizing.
Anodizing
The treated titanium product is used as the anode and put into the configured electrolyte solution. Stainless steel or titanium is used to make the cathode. After powering on, it can be seen that the color will change differently with the increase of voltage, from the initial bronze color of about 5V to the green color of about 110V.
Hole sealing
In order to better improve the antifouling property of the anodic oxide film, the anodic oxide product is washed with flowing water to remove the surface electrolyte solution, and the hole is sealed in 80 ° deionized water for 20 minutes.
Dryness
After sealing the hole, wipe off the water on the product surface and put it into the oven for drying.
Applications of Grade 5 titanium bolts
Grade 5 titanium bolts are a popular type of fastener utilized in several industrial and commercial applications. These fasteners have exceptional properties that make them ideal for use in challenging conditions where other materials may fail. The following are some of the applications of Grade 5 black titanium bolts:
1. Aerospace – Grade 5 titanium bolts are used in the aerospace industry due to their strength, lightweight, and corrosion resistance properties. These bolts are primarily used in critical applications such as aircraft engines, landing gears, and outer panels.
2. Automotive – Grade 5 black titanium bolts are often used in high-performance vehicles due to their excellent strength-to-weight ratio. These fasteners are suitable for use in suspension systems, engines, exhaust systems, and bodywork.
3. Medical devices – Grade 5 titanium bolts are biocompatible and are commonly used in the manufacture of medical implants. These bolts are also used in orthopedic implants, such as knee and hip replacements, due to their strength and corrosion resistance properties.
4. Marine – Grade 5 titanium bolts are ideal for use in marine environments as they are resistant to saltwater corrosion. These bolts are commonly used in the manufacture of marine components such as propellers, shafts, and rudders.
5. Construction – Grade 5 titanium bolts are suitable for use in construction applications due to their high strength and corrosion resistance properties. These fasteners are used in critical applications such as bridges, high-rise buildings, and other heavy infrastructure projects.
In conclusion, Grade 5 titanium bolts are versatile fasteners that offer excellent mechanical properties suitable for various critical applications where strength, corrosion resistance, and lightweight are essential.
