Description
В процессе работы наружна поверхность В ТЗП омываетс гор чей средой, а поверхность Г охлаждаетс относительно холодной средой. Низка теплопроводность ТЗП толщиной rl (двуокиси циркони ) обеспечивает требуемое снижение температуры основы 1, например, на 200°С, что повышает ее несущую способность и надежность , При теплосменах, например при резком снижении температуры среды со стороны ТЗП, углублени 2 играют роль неподвижных центров (и дл ТЗП и дл основы 1), относительно которых происходит радиальна деформаци ТЗП и основыDuring operation, the outer surface B of the heat-treating component is washed by a hot medium, and the surface D is cooled by a relatively cold medium. The low thermal conductivity of the thermal conductors with a thickness of rl (zirconium dioxide) provides the required decrease in the temperature of the base 1, for example, by 200 ° C, which increases its load-bearing capacity and reliability. During heat exchanges, for example, with a sharp decrease in the temperature of the medium from the side of the thermal conductors, depressions 2 play the role of fixed centers (both for TZP and for base 1), with respect to which radial deformation of TZP and base
Из-за разницы в деформаци х ТЗП и основы возникают касательные напр жени на границеТЗП-основа, направленные радиально от неподвижного центра. Поэтому , чем больше шаг а между ними, тем больше раст гивающие (или сжимающие)Due to the difference in the strains of the TZP and the base, tangential stresses arise at the boundary of the TZP base, directed radially from the fixed center. Therefore, the larger the step a between them, the more tensile (or compressive)

Проведенное расчетно-теоретическое исследование показало, что в ТЗП с данными отличительными признаками в сравнении с ТЗП по прототипу при одних и тех жеThe calculation and theoretical study showed that in the TZP with these distinctive features in comparison with the TZP of the prototype with the same
