Embodiment 1

[0040] A ceramic coating method, the details are as follows:

[0041] The coating device used in this coating method includes: a coating machine, a vacuum device, a fixture, a sandblasting machine and a cleaning machine. The coating machine, the fixture, the sandblasting machine and the cleaning machine are set independently of each other. It includes an A cavity and a B cavity, both of which are connected to the vacuuming device, and the B cavity is provided with a fixed part that drives the clamp to rotate. Here, the coating machine is a magnetron sputtering coating machine; the sandblasting machine is an automatic sandblasting machine; and the cleaning machine is an ultrasonic cleaning machine.

[0042] Above-mentioned ceramic coating method specifically comprises the following steps:

[0043] The pretreatment step is specifically: including sandblasting and cleaning. The sandblasting is specifically: using a sandblasting machine to spray alumina powder on the surface of t...

Embodiment 2

[0059] The difference between this embodiment and embodiment 1 lies in that: the first inactive metal layer and the second inactive metal layer are titanium layers, and the active metal layer is an aluminum layer. The thickness of each layer and the actual process of coating are the same as in Example 1.

[0060] The product performance that present embodiment obtains is the same as embodiment 1.

[0061] In addition, other inactive metals (copper, silver, etc.) can also be used in the first inactive metal layer and the second inactive metal layer, and other active metals (such as magnesium, potassium, etc.) can also be used in the active metal layer. etc.), and then slightly modify the coating parameters according to the actual situation to meet different needs.

Abstract

The invention provides a conductive composite film, a ceramic coating method for ceramic coating products and a device for using the ceramic coating method. The conductive composite film comprises a first inactive metal layer, an active metal layer and a second inactive metal layer which are arranged in sequence. The surface of a corresponding target is excited by an intermediate frequency power source to generate argon plasma, argon ions bombard the corresponding target, a corresponding film layer is formed on a product to be coated, the structure is simplified, the preparation method is simplified, and the coating property of ceramic is good. The ceramic coating method for the ceramic coating products comprises the steps of coating of the conductive composite film on the ceramic, a clamping step, a vacuuming step, a plasma pretreatment step and a clamp removal step, the process is simplified, the process parameters are easy to control, and the ceramic coating products with good performance are obtained. According to the device for using the ceramic coating method, all parts are easy to obtain and easy to operate.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a conductive composite film, a ceramic coating method including the film layer and equipment used therein. Background technique [0002] Ceramic mobile phone and watch cases are emerging industries. In order to make room for other components and reduce the internal wiring of the case, it is necessary to perform PVD coating on the surface of the inner cavity of the case. [0003] The coating method in the traditional technology is applied to ceramics, and the following defects occur: (1) the film layer is too thick and occupies a large space; (2) the film layer is easy to detach. [0004] Therefore, in order to meet the market demand, it is of great significance to develop a film layer and film sticking process suitable for ceramics with excellent performance. Contents of the invention [0005] The first purpose of the present invention is to provide a conductive composite ...
