Optimization of spark alloying operating parameters of tribosystem parts
Tóm tắt
The paper presents the results of optimized studies of the processing parameters of steel surfaces by electro-spark alloying. It is shown that with increasing capacitor capacitance with simultaneous voltage reduction between the alloying electrode and the surface treated, the adhesive constituent of the friction force decreases. A relationship is found between the alloying energy parameters and the physico-mechanical and tribological properties of the treated part surface layers.
