In recent years, the titanium industry has developed rapidly. The downstream titanium products, such as titanium kitchen utensils, titanium daily products, titanium jewelry and other colorful products have entered the people's lives with a healthy lifestyle. However, titanium daily products have always had an unsolvable bottleneck problem—the surface hardness is low, especially when titanium is used as a chopsticks and a spoon, etc., it is inevitable that scratches will occur with the porcelain tableware, which will make titanium chopsticks, etc. The product left dark gray titanium swarf that could not be removed on the surface of the porcelain. These titanium scratches are not harmful to the human body, but they can damage the appearance of the tableware and reduce the use experience.
