On Friday, after a short meeting at the company's headquarters, we went to the Technological Institute in Aarhus, about 120 kilometers away. There the surfaces of Ansuz and Børresen products undergo a refining process. The term "particle accelerator" occasionally appears in the product information. Oh yes, to begin with there are two smaller facilities of this kind there, which take care of accelerating particles with a voltage of 200,000 volts and shoot them at the objects to be treated. Secondly, there is even a reference to the huge facility in Geneva, which is operated by the European organization for nuclear research CERN: For them, parts are surface treated in Aarhus. However, the devices that give the Ansuz Darkz feet, for example, an extremely hard surface are correctly called "Magnetron Sputtering Units" and the process which the Ansuz objects undergo is called "HiPIMS deposition", the abreviation HiPIMS standing for High Power Impulse Magnetron Sputtering: The objects are placed in a chamber, which is evacuated by two large high vacuum pumps. Argon gas is then fed into the chamber and argon atoms are shot at the surfaces of the objects to free them from any trace of oxidation. The argon particles then release atoms from ingots made from the metal species intended to be bonded to the surfaces. These are then accelerated onto the objects with a voltage of 1,000 volts. This energy-consuming process takes 62 hours. Bjarke Holl Christensen, Senior Specialist for Tribology and Materials at the Technological Institute, points out, and not without a touch of pride, that this process is not subject to chemical laws. The compounding of materials realized here happens solely because of the high kinetic energy with which atoms are shot into the surface of the objects. Whether it's about particle accelerators or Magnetron Sputtering Units: The effort required to refine the surfaces of Ansuz and Børresen products is enormous.
