Diamond confession: my troubles and pride

I am a diamond, alias diamond, Diamond, ダイヤモンド, 다이아몬드, Алмаз, Berlian, the main component is C, parents are nature or human. We have two major families: natural diamonds and synthetic diamonds. The former is unknown, and the latter was born in China on December 6, 1963. And I belong to the second largest family - synthetic diamond.
I am a synthetic diamond, I am proud, I am proud, because I am the hardest in the world, "no diamonds, do not take porcelain to live" is to say mine. My thermal conductivity is extremely high, 25 times that of copper at liquid nitrogen temperature; I have good chemical stability, I can't use acid and alkali; I have a very high reflectivity, can produce high brightness, and can also flash. But only this hard, I have won the appreciation of human beings, and I have produced a lot of my brothers with lightning speed, from 5~14 mm single crystal large particles, single crystal small particles, broken materials, micro powder, to Nano-scale particles, deposited diamond diaphragms with an area of ​​300 square centimeters or even larger, sintered bodies of various shapes and sizes, composite sheets of diamond and cemented carbide, from large diamond saw blades with a diameter of 4000 mm to Nano-diamond abrasive paste, suspension, polishing liquid, can be said to be a total of forests. Since then, my brothers have been thorns and thorns, passing through the silicon carbide, smashing brown sapphire, attacking the city, and repeatedly fighting for merits, widely used in geological and petroleum exploration, construction and civil engineering, stone processing industry, automobile industry and other fields. Moreover, it has been continuously applied in many new fields such as gemstones, crystalline silicon, medical equipment, ceramics, wood and composite non-metallic hard and brittle materials. The demand for human beings has also increased significantly, and it has gradually developed into artificial intelligence and high precision.
I am synthetic diamond, I am proud, I am proud, but I also have troubles. Maybe it's because I am so handsome (the jewels are dazzling, handsome, A Diamond Is Forever), or maybe because I am too hard, in short, too few friends, I am reluctant to squat with me, causing me to cut, polish, etc. It falls off prematurely, the utilization rate is low, and some even withdraw from the position without killing the enemy, disappearing into the endless debris, and buried it for a lifetime. Smart humans, of course, did not sit and watch, so various diamond coatings came into being, such as electroless plating, electroplating, vacuum evaporation, vacuum ion plating, etc., to help us put on a layer of metal warfare, so that our combat violence increase. But for these kinds of coating methods, I still want to express my opinion: electroless plating and electroplating are especially uncomfortable when wearing armor. Although I am not afraid of acid and alkali, it is really uncomfortable to soak in acid for a long time. Recently, I heard that environmental protection is severely hit. It is estimated that these two people will soon die. Although vacuum evaporation plating has no acid and alkali, but it is baked for several hundred degrees Celsius for a long time, the taste of burning is quite uncomfortable. Some brothers can't stand this process. Then, it turned into graphite, and the shirts that we wore were too thin to meet our needs, until the appearance of vacuum ion plating changed the status quo.
I am synthetic diamond, I am proud, I am proud, I am no longer worried about wearing a battle suit. With the strong support of the company, the Super Hard Wheel Material Manufacturing Division adopts fully automatic intelligent equipment and has invested heavily in the development of a new intelligent superhard material plating process. Its characteristics are: coating coverage of 100%, coating thickness range of 1% ~ 30% can be freely controlled; coatings of various types, can be plated with titanium, nickel, molybdenum and other almost all metal elements and most alloys and various metal compounds The coating forms a strong ionic bond with the super-hard material. The combination is firm and not easy to fall off. According to the actual needs of the user, the optimal "private custom" coating can be developed and designed; environmentally friendly production, no waste gas, waste water Contaminants, clean and efficient. At this point, I can wear metal shirts quickly and evenly in a comfortable environment. There is no acid corrosion, no fire smoke, and I am not happy. In addition, in addition to wearing a battle suit, the super-hard grinding wheel material manufacturing division also directly from my appearance, using special techniques to make me covered with bumpy pits, such as the surface of the moon. I refused at the beginning, but when my friends increased and my fighting power increased, I smiled happily.
Well, not much to say, I have to hurry to prepare for the 4th China (Zhengzhou) International Abrasives Grinding Exhibition.
