Surface Modification of AISI 4140 Steel Using Electrolytic Plasma Thermocyclic Treatment

Materials and Manufacturing Processes, 2010
Surface modification of AISI 4140 steel has been carried out by using electrolytic plasma thermocyclic treatment (EPTT). Cyclic voltage between 320 and 250 for stipulated period of 1, 2, 3, 4 s and 2, 3, 4, 5 s, respectively, has been performed. At the same time, the effect of average voltage and duration on process has been studied.

RESEARCH OF THE CURRENT STATE AND TECHNOLOGICAL OPPORTUNITIES OF ELECTROLYTE-PLASMA CHEMICAL HEAT TREATMENT OF STEELS

NNC RK Bulletin, 2023
In the modern world, one of the most important requirements for the production of structural steel parts in machine building is improved hardness and wear resistance. Electrolyte-plasma chemical-thermal treatment is one of the best solutions for this problem, as the surface of steel is modified while the core of the part remains in a ductile state for ...
