 Report on research work: 115 pages, 32 figs, 25 tables, 106 references. COATING, ADHESION, CONTACTS, CONTACT RESISTANCE, THERMOELECTRIC CONVERTERS, MECHANICAL IMPACT. The object of research is anti-diffusion structures of metal-thermoelectric material based on Bi-Te. The purpose of the work is to establish rational values of contact electrical resistance in anti-diffusion structures of metal-thermoelectric material based on Bi-Te and to develop technological methods and materials, to create anti-diffusion structures with high mechanical strength and optimal values of contact resistance. Research methods – mathematical physics, computer simulation of thermal and electrical processes in a thermoelectric environment, experimental methods of thermoelectric materials science, experimental methods for determining adhesion and contact resistances of anti-diffusion coatings. As a result of the work, a new computer method for designing thermoelectric converters was proposed, with regard to the electrical and thermal resistances of the contacts of the connecting, anti-diffusion and electrically insulating layers. A technological method and materials were developed for creating structures of an electrically neutral metal-thermoelectric material based on Bi-Te with high strength and optimal contact resistance values. A methodology was developed and equipment was created for experimental studies of contact resistances and adhesion. The results of the work were implemented in the development and manufacture of thermoelectric two-stage cooling modules with rational structures of nickel anti-diffusion layer-thermoelectric material based on Bi-Te, which made it possible to increase the stability of the modules under the action of impacts to a peak acceleration value of 2000g, which made it possible to improve the reliability of space-purpose cooling modules used in the EU space programs.
