Abstract:
Metal-ceramic composite materials due to their physico-mechanical properties have a wide spectrum of application (space, aircraft engineering, chemistry, agriculture, machine-building industry). Georgia has less experience in the above mentioned materials and producing products from these materials. Hence working up the technology of producing and implementing metal-ceramic composites and proper products from them is an actual problem. <br />Among numerous ways of producing metal-ceramic composite materials, especially important is Self-Propagating High-Temperature Synthesis (SHS) accompanied with pressure shaping because of energy saving, cheapness, effective control of the process and the possibility of giving the planned properties to the materials. However this process has strictly specified technological parameters, SHS process is going fast and so the existed technologies (pressing, extrusion) of pressure shaping (SHS) provide producing only finite sized piece products. <br />The combined process of SHS and rolling cannot provide the continuity of synthesis either, as the process is terminating because of intensive thermal losses in the deformation zone. <br />By combining SHS and electric rolling processes it is practically possible to produce products of any length. For this purpose, an innovative technological process of producing composite materials has been developed in the institute. It is based on the combination of Self-Propagating High Temperature Synthesis and electric rolling. On a specially constructed laboratory electric-contact rolling mill by passing the heating current through the deformation zone synthesis is initiated. By synchronization of the speeds of the burning front displacement and of rolling and compensation of thermal losses in the deformation zone continuous rolling of the hot mass is carried out. <br />There is a perspective of continuing the started work. After certain theoretical research and working up the suitable technology, which in present conditions is considerably simplified, it is possible to produce not only plates, but multiprofile and multifunctional products as well.
