Metal materials are suitable for finishing, with excellent natural color and texture.
They can also be colored by oxidation and electroplating process to increase beauty, or sandblasting, wire drawing and other processes to strengthen texture [1], thus they are widely used as key materials for earphones.
In the other three materials, chloride ions (Cl-) and sulfate ions (SO42-) were detected.
In order to verify the effectiveness of the measures, the prepared materials and untreated aluminum alloy materials were placed in a sulfuric acid solution with a concentration of 0.5% (vol), 1.0% (vol) and 1.5% (vol) for 72 hours, and weighed it every 24 hours.

The maximum principle stress and the minimum principle stress are all less than the strength of the surrounding rock supporting, and this will not cause material damage so as to structural damage.
According to the survey material, the strata of the tunnel are generalized as mild clay and bedding rock, and the special distribution of each stratum is also decided.
The maximum principle stress and the minimum principle stress are all less than the strength of the surrounding rock supporting, and this will not cause material damage so as to structural damage.
