At the university (Novosibirsk) the technology of diamondlike coatings is developed for optical systems in the wide range of IR-optics. Coatings have high adhesion to a variety of substrates and are suitable for application as medical antibacterial coverings, a friction reducing coating with a low friction coefficient, antirust coats. The laboratory looks for partners for technical cooperation and technology licensing.Description
The problem of low adhesion (coupling of diverse surfaces) is extremely important for a number of technical processes in medicine, optics, automotive industry. In these areas issues of increase in performance and longevity of the equipment, workplace safety and standards compliance when maintaining other necessary characteristics, such as optical features, durability, hardness are particularly acute. At the same time when the expected adhesion is absent other properties of the material become irrelevant. The adhesion significantly depends on climatic conditions: in the conditions of the increased humidity, extremely low or high temperatures, an overpressure some coatings deteriorate. Thus, development of optimal conditions for synthesis of coatings with the established characteristics is difficult and critical task. Team of researchers from NSU developed diamondlike coatings (DLC) synthesis process for glasses, silicon, germanium and other metal substrates. At the heart of a method – vacuum plasma ion-beam implantation of ions stream into the substrate. Such approach provides an optimum ratio of sp3/sp2 hybridized atoms of carbon that is one of the most important characteristics of the coating. During the experiments the main conditions of synthesis of coatings are investigated, defined and scientifically based. Out coatings have a high adhesion to a substrate: the separation is absent when scribing by a diamond Berkovich nanoindentor with pressure up to 50 mN. Hardness of a coating is up to 20 GPA. Film thickness – 600 nanometers. Spectroscopical measurements show maximum transmission rate for unilateral a-C: H coated germanium 67% on a wavelength of 5 microns, and 51% for monocrystal Ge. Coatings with a hardness of 40 GPA are made by arc discharge method. It is shown that under certain conditions such coverings have hydrophobic features. Conditions of synthesis of diamond like coatings depend on the materials used, thus, we developed the technology for optimization of synthesis process for a number of nonconventional spluttering substrates. Carbon diamond like (a-C and a-C: H) films are used as antireflection and protective coatings for solar panels, optical and laser systems, including IR optics. They have also been proven as an efficient friction reducing coating in mechanical devices and in medical implants. The laboratory looks for partners for technical cooperation, scientific cooperation and licensing.Advantages and Innovations
