The article is devoted to improving the physical, mechanical and operational characteristics of cast internal combustion engine pistons made of aluminum alloy using secondary charge. The advantage of the proposed approach is that these parts are manufactured from any aluminum alloy using the remelting of failed internal combustion engine parts of the same name. The paper shows that while using a secondary charge in the form of remelting failed parts of the same name, the quality of cast products not only does not deteriorate, but, on the contrary, their physical and mechanical characteristics even increase. It should be noted that the high density of the alloy obtained from remelting failed pistons and the high degree of its modification confirmed the authors’ assumption that in this case refining and modification operations can be avoided. The presented approach using the remelting of failed parts makes it possible not only to save fresh charge materials, but also to preserve the chemical composition of the primary parts, and, consequently, the level of their physical, mechanical and operational characteristics.

Modern technologies are the most important component for any state. Today, advanced technologies allow to create any mechanisms at the level of atoms and molecules. For the production of machines, aggregates and their individual components, new nanomaterials and nanotechnologies are used, which reduce friction repeatedly and with high efficiency, protect parts from damage, save energy and increase the reliability of machine parts as a whole. Virtually in any mechanism, some parts focus on the main load. In this study, such a detail is the steel clamping collet 65G. A method of plasma siliconizing is proposed for hardening its inner surface. The raise of this characteristics will allow to increase its service life, and therefore will ensure more reliable operation of both a separate mechanism and production as a whole. This allows the enterprise to become cost-effective and competitive. In this paper, the magnitude of the effect of the silicon atoms introduction into the surface layer of a part on wear resistance and durability is investigated. Research and subsequent processing of the results using Statistica software for statistical analysis shows an increase in the strength characteristics by 2.6 times.
