THE ECOLOGICAL IMPORTANCE OF USING EXPLOSIVE MATERIALS FOR OBTAINING LAYERED STRUCTURES

The paper presents an ecological technology regarding the use of explosive materials in obtaining unconventional layered structures. It is emphasized that the use of the presented method contributes substantially to the minimization of the action of toxic factors on the environment compared to classic welding technologies. The reduction of harmful effects on the environment is due to the extremely short duration of the process, the entire amount of explosive material being consumed almost instantly. The subject of the paper focuses on those parameters that must be taken into account as a result of the detonation of the explosive charge in order to obtain the most effective results in terms of environmental protection. Experimental results regarding the development and testing of such structures are also presented in the article. In this regard, the obtaining of layered metal structures based on aluminum with a stainless steel texture was studied. The technology presented is of the latest generation, with applicability in the chemical industry, but also in the production of civil protection equipment. The paper begins with a short introduction on the advantages of obtaining such materials, continuing with a theoretical presentation and a numerical simulation of the process, so that at the end the results of the experimental tests carried out on the structures thus obtained are exposed.
