Medical titanium common problems
Medical titanium plate in the external processing and product processing, will encounter some of the following common problems:
1, weld defects: weld defects more severe, the choice of mechanical and mechanical grinding method of compensation to compensate for the occurrence of grinding traces of the formation of uneven appearance, the impact of beautiful.
2, the appearance is not common: only the weld pickling passivation, but also the appearance of uneven, the impact of beautiful.
3, scratches difficult to get rid of: the entire pickling passivation, can not be processed in the process of removing all kinds of scratches, and can not get rid of scratches, welding spatter and attached to the medical fixed titanium surface carbon Steel, splash and other impurities, resulting in the presence of corrosive media under the conditions of chemical corrosion or electrochemical corrosion and rust.
4, grinding and polishing passivation uneven: grinding and polishing process for pickling passivation treatment, the larger area of the workpiece, it is difficult to reach the uniform disposal role, can not be aspiration of the uniform appearance. And working hours costs, accessories costs are higher.
5, pickling can be limited: pickling passivation paste is not all-powerful, the plasma cut, flame cut and black oxide produced, more difficult to get rid of.
6, For the elements of the formation of more severe scratches: In the lifting, transportation and layout process, bump, delay, hammer and other human factors to form more severe scratches, making the appearance of more difficult to dispose of, and also after the occurrence of corrosion The main reason.
7, equipment elements: In the profiles, sheet bending, bending process, the formation of scratches and creases is the main reason for the occurrence of corrosion after disposal.
8, other elements: medical titanium plate material in the acquisition, storage process, because lifting, shipping process bump and scratches are more severe, but also one of the reasons for the occurrence of corrosion.
