This September, the 19th annual World Surface finishing Conference (Interfinish 2016) will be held in Beijing.

This four-year world surface finishing conference was first held in China.

In China, when manufacturing from a strong strategy to fully start, the conference held in Beijing has a symbolic significance.

There will be more than 20 countries and regions of surface technology professionals ⼠ and entrepreneurs, scholars thousands of people gathered in Beijing, exchange modern surface finishing technology.

During the same period, the international Surface finishing exhibition exhibited the latest products and technical achievements of the surface treatment industry.

Although the surface finishing industry is very professional, it is closely related to mass life and modern manufacturing, it is necessary to popularize the knowledge about surface engineering to the public.

The word of the surface is from an engineering point of view refers to the part of the material exposed to the outside world, if it is expressed from a microscopic point of view, it refers to the area of one or more atoms of a solid layer.

Because the particle (molecule or atom) on the surface does not have a neighbor particle on the surface of the space or other medium, its physical and chemical properties are markedly different from the inside of the solid. Some special properties arise.

The study of these properties of the surface forms a science and produces corresponding techniques, such as surface technology.

Of course, the word surface can also refer to the external phenomenon of things, that is, the so-called surface phenomenon, appearance, and so on.

What is Surface Engineering?

Surface engineering is the technology and process of applying surface technology to products.

It can be said that the use of various industrial technology to change the surface of the material shape so that it conforms to the desired effect of the process.

This process is also known as surface treatment.

The corresponding surface treatment methods are also known as surface treatment techniques, which can be classified into the surface coating, surface modification, etc.

Surface engineering is closely related to people’s production and life. It is no exaggeration to say that all products involved in modern manufacturing must undergo such or such surface treatment. Without surface treatment technology, there is no modern manufacturing.

Our daily life with surface engineering is directly related to a variety of surface decoration technology. Surface decoration in decorative products and beautifying ⼈ People’s lives played a pivotal role.

Whether it is metal products or non-metallic products, including household appliances, daily hardware, fitness equipment, children’s toys, and so on, all kinds of surface decoration technology.

Surface decoration is an important application field with a large quantity in surface engineering. The most typical surface decoration is to display metallic textures and precious decorative chrome plated.

This is the application of electroplating technology to metal or non-metallic surface decoration works. Modern cars from bright chrome-plated aluminum wheels to ABS plastic chrome decorative strips, etc., have been using this technology, enduring, become a classic.

As for the application of a variety of color paints, it is more numerous, in a large number of products widely used, especially buildings and automobiles, are all decorative coating is the most important field, become a modern society beautiful scenery.

However, surface decoration is only part of surface engineering. Surface Engineering also has some more important applications, such as surface corrosion protection engineering.

The corrosion of various materials is seemingly inconspicuous, deep ⼊ into the investigation is alarming.

To take the corrosion of our most common metal materials, we only cite the preface of a book published last year, suffice it to say: “Rust is known as the Great Destroyer and the devil.”

The Pentagon calls it “pervasive and ubiquitous threats.” The rust destroyed the car, broke the bridge, sank the ship, caused the house fire, and almost ruined the Statue of Liberty.

The United States pays $400 billion a year for rusting, more than all other natural disasters combined …

The book is Rust: The Longest War, published in March 2015, by Jonathan Waldman, a U.S. environmental journalist. The book was ranked eighth by the Wall Street Journal as the best Non-fiction Book of 2015.

It is a large number of real rust that brought about the harm of the story of universal anti-corrosion knowledge of popular science masterpieces. Therefore, people should attach great importance to the protection of corrosion, that is, the application of surface protection engineering.

Corrosion to human society is not only the destruction of metal materials, including cement, wood, and other non-metallic materials but also by its harm.

It is in space and in the universe that corrosion is also a terrorist killer of cosmic exploration equipment that endangers space.

Therefore, the corrosive discipline and the profession, has been the country attaches great importance to the domain and the profession. Almost all polytechnic universities and colleges have a major in corrosion and protection.

This is the use of surface treatment technology so that the surface of the material with a variety of physical or chemical properties of the engineering field. For example, functional plating, functional coatings, and so on.

This surface modification treatment is not for decorative surfaces, nor is it or is not just for the improvement of surface protection performance, but to be assigned to the table ⾯ some matrix materials do not have the properties.

So that its surface has electrical, magnetic, optical, chemical, mechanical, biological, and so on.

So that ordinary material after such surface treatment, with rare materials to have the nature. Its significance is serious.

Only with good conductive silver as an example, we can not all use pure silver to make high conductivity of the wire and electronic devices, but in copper, aluminum, and another metal surface silver-plated, so that copper, aluminum and so have silver conductive properties.

Also such as the use of stainless steel, titanium, and other metal materials such as the production of human bones and other components ⼊ body is commonly used in modern medicine.

The biological affinity layer formed on the surface of this kind of material is an important branch of modern surface technology.

Obviously, we all hope that this field has made considerable progress and development. This is only a small branch of surface modification technology.

More applications in the field of micro-processing technology, modern sensor field, microelectronics manufacturing field, nanotechnology, and so on are of great significance.

Finally, some of the technical expertise in surface treatment technology, based on its principles, has also developed into a direct manufacturing of products or new materials technology.

Typical of such as PCB manufacturing, electransforming, Chip interconnection, nano-materials manufacturing, composite materials manufacturing and so on. It shows that new manufacturing can ⼒ and innovate.

And these manufacturing processes are very fine, precise, some directly belong to the field of microelectronics manufacturing.

Just printed circuit boards For example, all modern electronic products are inseparable from the printed circuit board. and PCB manufacturing is inseparable from electroplating technology.

From the early Single-layer board to the now popular multilayer board, from hard rigid board to the soft sex board, in the manufacture process must use the galvanization, the electroless plating, the etching, the encapsulation and so on surface technology.

Therefore, in order to fully express all the application areas covered by surface engineering, people use the word surface finishing to describe the application of surface technology.

At this point, the decoration, not refers to the decorative, but includes decoration, modification, protection, function and based on surface technology precision molding.
