Surface treatment technology for titanium and titanium alloys: detailed explanation of grinding process

In the processing of titanium and titanium alloys, surface treatment technology is crucial, and grinding, as a key auxiliary process, plays an indispensable role. Grinding is mainly the use of grinding tools to perform precision machining on the surface of workpieces, in order to remove various surface defects such as cracks, folds, unevenness, and oxide scales, thereby improving the overall quality of the workpiece.
Grinding treatment is not limited to repairing surface defects, and according to actual needs, full surface grinding can also be carried out. For some special titanium alloy materials, such as those that are prone to strong aging during alkali washing or hydrogen absorption during acid washing, grinding treatment has become an ideal alternative solution. It can effectively avoid the problems that may occur during these chemical treatment processes and achieve the desired surface treatment effect.
In addition, sand belt grinding has been widely used in the surface treatment of titanium and titanium alloy finished pipes, rods, and plates. By using sand belt grinding, small defects on the surface of these finished products can be further removed, significantly improving the smoothness of the surface and meeting higher standards of appearance and quality requirements.
A significant advantage of grinding treatment is that it does not affect the chemical composition of the processed material, and the residual stress of the plate is also kept at a low level. This is due to the precise control during the grinding process and the fine operation of the grinding tool. In addition, with the continuous improvement of the automation level of grinding equipment, the accuracy and efficiency of grinding processing have also been significantly improved.
However, grinding treatment is not without challenges. On the one hand, the cost of grinding is relatively high, which to some extent limits its widespread application. On the other hand, there are certain requirements for the flatness of the processed material to ensure the smooth progress of the grinding process and the final processing effect. In addition, the titanium dust generated during the sanding process is flammable, so strict safety measures need to be taken to ensure the safety of operators.
Grinding treatment plays a crucial role in the surface treatment of titanium and titanium alloys, and its importance cannot be ignored. Titanium and titanium alloys have been widely used in various fields such as aerospace, medical, chemical, and sports equipment due to their high strength, low density, excellent corrosion resistance, and biocompatibility. Grinding treatment, as a key step in the processing of these materials, can not only improve the surface roughness and aesthetic appearance of the materials, but also enhance their surface hardness and wear resistance, thereby extending their service life.
With the continuous development of technology, grinding technology is also constantly innovating and improving. For example, the emergence of advanced technologies such as ultra precision grinding and laser assisted grinding has further improved the efficiency and accuracy of grinding processes, and expanded the application range of titanium and titanium alloys.
