With the development of the economy and the improvement of living standards, people like to concentrate on decorations such as watch cases, watch straps, clothing, lighting, spectacle frames, indoor and outdoor decorative parts, hardware luggage, mobile phone cases, mobile phone screens, sanitary ware, food packaging and so on. Decorated colorfully. 2. Application of coating technology in cutting tools, molds and other metal cutting tools

In life, we will see drills, milling cutters, molds, etc. in various colors such as golden yellow, cobalt copper, black, etc. These are the coating tools processed by the coating technology.

(1) The golden color is coated with TiN (tin) and ZrN (bercylium nitride) coating on the tool. TiN is the first generation of widely used hard layer materials.

(2) The black ones are coated with TiC and CrN coatings on the cutting tools. (3) The cobalt copper color is coated with TiALN coating on the tool. 3. Application of coating technology in architectural glass and automotive glass Architectural glass has two basic functions of light transmission and heat insulation. Ordinary glass can radiate energy through most of the sunlight, which is very beneficial for lighting and absorbing the energy of sunlight.

For space infrared radiation, although ordinary glass can prevent the indoor heat from directly passing through the outdoor, the secondary heat dissipation after the heat is absorbed by the glass will also cause great losses. With the development of economy, ordinary glass has become more and more unable to meet people's requirements. The solar control film and low-emissivity film can just make up for the shortcomings of ordinary glass in this regard. The solar control film can meet the requirements of reducing indoor temperature in low latitude areas; while the low-emissivity film can meet the requirements of fully receiving solar radiation energy and preventing indoor heat outflow to the maximum extent in high latitude areas.

On glass, a coating of TiO2 can make it anti-fog, anti-dew and self-cleaning glass. This process has a good application in automotive glass.

4. Application of coating technology in flat panel displays

All types of flat panel displays use various types of films, and almost all types of flat panel display devices require the use of ITO films to meet the requirements of transparent appliances. It is no exaggeration to say that there is no flat panel display device without thin-film technology.

5. Application of coating technology in solar energy utilization When it is necessary to effectively utilize solar thermal energy, it is necessary to consider adopting an absorbing surface that absorbs more sunlight and less loss caused by thermal radiation. The peak of the solar spectrum is approximately in the infrared wavelength range between 2-20µm. Because the spectrum of solar radiation and thermal radiation are different in wavelength bands, in order to effectively utilize solar thermal energy, it is necessary to consider the use of an absorbing surface with wavelength-selective properties.

The ideal absorption surface is that the absorption rate (α) of the solar radiation spectrum band (visible light band) is 1, and the emissivity (ε) of the thermal radiation band (infrared band) is 0. 6. Application of coating technology in anti-counterfeiting technology There are many types of anti-counterfeiting films, which can be divided into reflection type and transmission type from the method of use; from the film attachment method, it can be divided into direct coating type, indirect coating type or indirect coating clipping type.

7. Application of coating technology in aircraft protective coating

The titanium alloy fasteners of aircraft were originally plated with cadmium by electroplating. However, cadmium plating contains hydrogen, so during the flight, it is corroded by the atmosphere and seawater, and the coating is prone to "cadmium embrittlement" and even "air disaster". In 1964, ion plating was used to coat titanium alloy fasteners with aluminum, which solved the "cadmium brittleness" problem of aircraft parts.

In the ion plating technology, a "pseudo-diffusion layer" can be formed and the film structure can be refined by applying a negative bias to the workpiece, so the corrosion resistance of the film can be significantly improved.

8. Application of coating technology in optical instruments

The optical instruments that people are familiar with include telescopes, microscopes, cameras, rangefinders, and mirrors, glasses, magnifiers, etc. in daily necessities. They are all inseparable from coating technology. film, etc.

9. Application of coating technology in the field of information storage Thin film materials are used as information to record in storage media, which has unique advantages: due to the thin film, eddy current loss can be ignored; the magnetization reversal is extremely rapid; the bistable state parallel to the film surface Easy to keep etc. In order to record and store information more precisely, coating technology must be used.

10. Application of coating technology in sensors

In sensors, semiconductor materials whose electrical properties are extremely sensitive to physical quantities, chemical quantities and their changes are often used. In addition, most of them use the properties of the surface and interface of semiconductors, and their area needs to be increased as much as possible, and they can be produced industrially and at low prices, so there are many cases where thin films are used.

11. Application of coating technology in integrated circuit manufacturing The protective layer (SiO2, Si3N4), electrode pipeline (polysilicon, aluminum, copper and its alloys) in the transistor circuit are mostly CVD technology, PVCD technology, vacuum evaporation metal technology, etc. Magnetron sputtering technology and radio frequency sputtering technology. It can be seen that vapor deposition is one of the core technologies for preparing integrated circuits.
