When titanium screws are not subjected to any surface treatment, the color of the entire screw is silver-gray, and it is also very common in daily life. Sometimes there are many different colors of titanium screws on bicycles and cars. These colorful Titanium screws are so bright and colorful after a certain surface treatment. The following titanium screw manufacturers will share with you how to remove the reaction layer of titanium screws.
1. Sandblasting
The titanium screw manufacturer impacts sand particles on the surface of the titanium screw, thereby generating intense sparks, and the temperature rise reacts with the surface of the titanium screw, forming secondary pollution and affecting the surface quality. It takes 15 to 30 seconds to remove the sticky sand, surface sintered layer and part of the oxide layer on the surface of the casting, and the reaction layer on the remaining surface is quickly removed by chemical pickling.
2. Pickling
The use of pickling can quickly and effectively remove the reaction layer on the surface of the titanium screw without causing pollution of other metal elements.
Titanium screws look like steel with a silver-white luster. It is a transition metal. Pure titanium screws have high strength, low density, high hardness, high melting point and strong corrosion resistance, so they can be used in many fields.
