[0002] Titanium and its alloys are widely used in a wide range of fields, including aerospace, medical devices, chemicals, and marine engineering, due to their excellent properties, such as high strength, low density, good corrosion resistance, and biocompatibility. In these applications, titanium and titanium alloy bars serve as important structural materials or component blanks, and their surface quality has a crucial impact on product performance, service life, and appearance.
[0003] During the processing of titanium and titanium alloy bars, after rolling, forging and other processes, defects such as scale, burrs, scratches, and uneven roughness usually appear on the surface of the bars. These surface defects not only affect the aesthetics of the bars, but more importantly, they reduce key performance indicators such as corrosion resistance and fatigue strength. For example, in the aerospace field, aircraft engine components have extremely high requirements for the surface quality of materials. Tiny surface defects may lead to stress concentration, which in turn causes premature failure of components and seriously affects flight safety. In the field of medical devices, such as implants such as artificial joints, excessive surface roughness can trigger rejection reactions in human tissues, affecting the service life of the implants and the patient's recovery effect.
