The technology of thermocyclic treatment fine‑module gears has been improved, which makes it possible to increase their wear resistance by 30–40 %. Gears were subjected preliminary cyclic heating and subsequent impulse hardening. In all cases hardening, a martensitic structure is formed, provides high rigidity the material. sizes plates depend on temperature during quenching. During heat up 450...

Applications of lithium-ion batteries are widespread, ranging from electric vehicles to energy storage systems. In spite nearly meeting the target in terms density and cost, enhanced safety, lifetime, second-life applications, there remain challenges. As a result difference between characteristics cells, degradation process is accelerated for battery packs containing many cells. The development...
