Liu Renzhi (China Surface Engineering Association Technical Committee experts) Surface and surface engineering In September this year, the 19th World Finishing Conference (Interfinish 2016) will be held in Beijing. This four-year World Surface Finishing Congress is held in China for the first time. At the time when the manufacturing strategy in China was fully launched by the strategy of turning a strong country into force, the meeting was held in Beijing and has a landmark significance. There will be more than 20 countries and regions in the surface of technical professionals and entrepreneurs, thousands of scholars gathered in Beijing, the exchange of modern surface finishing technology. Over the same period and the International Surface Finishing Exhibition public display surface treatment industry's latest products and technological achievements. Although the surface finishing industry is very professional, but with the public life and modern manufacturing are closely related, therefore, to popularize the knowledge related to surface engineering is necessary. From the engineering point of view, the term "surface" refers to the part of a material exposed to space in contact with the outside world and, if expressed microscopically, the area of ​​one or several atomic layers of a solid surface. Since the particles (molecules or atoms) located on the surface have no neighbor particles toward the surface of the space or other medium, their physical and chemical properties are significantly different from those of the solid interior. Thus there are some special properties. Studying these properties of the surface creates a science that produces the corresponding technologies, such as surface technology. Of course, the surface of the word can also refer to the external phenomena of things, the so-called surface phenomena, appearances and so on. So what is surface engineering? Surface engineering is the application of surface technology in the product process and process. It can also be said that the use of a variety of industrial technologies to change the surface morphology, to make it in line with the expected effect of the process. This process is also called surface treatment. Corresponding surface treatment methods are also known as surface treatment technology, these technologies can be divided into categories from the surface coating, surface modification and surface modification. Surface engineering and people's production, life is closely related. It is no exaggeration to say that all products involved in modern manufacturing must be surface treated one way or another. Without surface treatment, there is no modern manufacturing. Directly related to surface engineering in our daily life is a variety of surface decoration techniques. Surface decoration plays a decisive role in decorating products and beautifying people's lives. Whether it is metal products or non-metallic products, including household appliances, household hardware, fitness equipment, children's toys, etc., must use a variety of surface decoration technology. Surface decoration is a large area of ​​surface engineering is an important area of ​​application. The most typical surface decoration is to show the metal texture and precious decorative chrome. This is the application of electroplating technology in metal or non-metallic surface decoration. Hyundai cars from bright chrome-plated aluminum wheels to ABS plastic chrome trim, etc., have been using this technology, enduring, become a classic. As for the application of various color paints, it is even more incredible. It is widely used in a large number of products, especially construction and automobiles, and is the most important application area of ​​decorative painting. Become a beautiful landscape of modern society. However, surface decoration is only a part of surface engineering. Surface Engineering There are some more important applications, such as surface corrosion protection project. Corrosion of various materials is appalling, in-depth study is startling. To cite the corrosion of our most common metallic materials, we cite only the preface of a book just published last year that is enough to explain the problem: "Corrosion, known as the" Great Destroyer "and" The Devil. "The Pentagon Called "a pervasive and ubiquitous threat." Corrosion destroyed the car, broken the bridge, sank the ship, caused a fire in the house, almost ruining the statue of liberty, and the United States paid $ 400 billion a year for rusting , More than the sum of all other natural disasters ...
