| Popis: | The efficient use of resources on the basis of the development of scientific and technical progress requires widespread implementation of new technologies for processing of metals, such as plas-ma, cathode-ray, detonation and other methods that allow to increase the lifetime of machines operation and reduce the materials and energy consumption throughout production.One of the new highly productive methods for obtaining a high-quality surface is the plasma sur-face processing (gouging) of metals. It is one of the most effective methods for surface pro-cessing applied in modern metal-processing facilities. Unlike other methods for surface pro-cessing this method includes the use of an electric arc and the produced plasma has a tempera-ture which reaches tens of thousands degrees Celsius. At such temperature, not only structural grade steel alloys can be processed, but in-fact all types of metals. The aim of this paper is to investigate the relation between the technological parameters of the process air-plasma surface gouging and the quality characteristics of the obtained surface lay-ers.The relations between technological parameters of the process air-plasma surface gouging of metals and quality parameters were obtained by using rotatable design of experiments and re-gression analyses techniques. |
