FUNDAMENTAL MANUFACTURING AND INNOVATIVE POTENTIALS OF DETONATION SPRAYING

Abstract

The article is devoted to the problems of development of detonation spraying, which is of interest both in connection with the discrete and cyclic nature of the technological process of coating application, and the high quality of detonation coatings. The purpose of the work is to substantiate and identify promising areas of innovative development of detonation spraying. The potentials of controlling discrete cycles of detonation spraying and the use of auxiliary steps in the process of applying a detonation coating are considered. It is proposed to improve the quality of detonation coatings by performing additional technological operations in the intervals between detonations spraying cycles. The structural and organizational order of the additive formation of detonation coatings is considered, which it is advisable to develop based on the hierarchical structure of the technology depth levels. The use of factors in the formation of detonation coatings at all levels of technological depth and structure synthesis of technology improves quality and maximizes the adaptation of detonation coatings to the planned operating conditions. The exceptional properties of detonation coatings can be enhanced by using the variability of the construction of technological processes for detonation spraying based on the discrete and cyclic nature of the coating formation process. The following aspects are highlighted as innovative developments and using priorities for detonation spraying: combining the detonation coating application process with additional treatment methods; applying coatings to surfaces of deep holes with small cross-sections; applying coating of blanks susceptible to thermal deformation; applying heterogeneous coating.
