Objective. Determining of heat treatment influence on a thermal blanket persistency and geometrical dimensions of its parts.Methods of research. Metallographical surface evaluations of a work-hardened parts geometrical measurements, measuring the adhesion.Results. The article details a detonation spraying of a metal powder coating using condensed high-energy materials based on engineered installation. Results of derived thermal blanket are featured.Scientific novelty. Scientific novelty. Behavior patterns of inner bodyof a nozzle assembly was established. It was identified that heat processing leads to changes in metallurgical structure in an anti-abrasion coating. It was defined that heat processing results in no cracks, cleavages or swellings.В ходе работы была проведена серия постановочных экспериментов по определению влияния термообработки (ТО) теплозащитного покрытия ТЗП-2 на стойкость покрытия. Сравнительные исследования проводились на 2 корпусах внутренних сопловых аппаратов (СА). Выбран оптимальный режим термической обработки.Practical value. During work the series of raising experiments were conducted on determination of influence of heat treatment (HT) of heatcover coverage of HCC-2 on firmness of coverage and geometrical sizes of details. Comparative researches were conducted on 2 corps of internal nozzle vehicles (NV). Optimal heat treatment conditions were established.
