AI Technical Summary

Problems solved by technology

It is generally emphasized that the metal film of mobile phones with good weather resistance is not scratch-resistant; while the metal film with good scratch resistance has poor weather resistance, and it is difficult to have both weather resistance and scratch resistance.
[0003] Even though the ceramic coating can have both weather resistance and scratch resistance, the color of the coating is uneven, the color difference is large, the plating rate is slow, and the yield rate is low. Deplating and replating are often required, and the production process is cumbersome, which greatly increases the manufacturing cost. Unfavorable market competition conditions, these are the shortcomings of the existing mobile phone coating technology

Abstract

The invention discloses a mobile phone coating film prepared by sputtering a high-entropy liquid metal alloy target material on a mobile phone. The mobile phone coating film has high hardness, strongcorrosion resistance and oxidation resistance, good adhesion to a substrate, ultra-high plating rate, high productivity and high yield.

Description

technical field [0001] The invention relates to a mobile phone coating, in particular to a mobile phone coating coated on a mobile phone with a high-entropy liquid alloy target material. Background technique [0002] The metal film layer coating on the existing mobile phone encounters the problems of weather resistance and scratch resistance. Generally speaking, the metal film of a mobile phone that emphasizes good weather resistance is not scratch-resistant; while the metal film with good scratch resistance has poor weather resistance, and it is difficult to have both weather resistance and scratch resistance. [0003] Even though the ceramic coating can have both weather resistance and scratch resistance, the color of the coating is uneven, the color difference is large, the plating rate is slow, and the yield rate is low. Deplating and replating are often required, and the production process is cumbersome, which greatly increases the manufacturing cost. Unfavorable marke...
