Summary: Titanium alloy, a difficult-to-machine material, is influenced by electro-discharge machining. Hybrid methods are used to improve the negative effects. This paper investigates the effect of hybrid electrical discharge machining processes on the surface integrity of Ti-6Al-4V alloy. The results show that the hybrid processes produce less microcracks, thinner heat-altered layer, reduced residual stress, and higher corrosion resistance compared to traditional electrical discharge machining process.

Summary: This study investigates the effect of electrolytic plasma processing on removing the defective layer from a damaged layer obtained after manufacturing operations. The results showed that the combined process of electrical discharge machining (EDM) and plasma electrolytic polishing (PeP) can effectively decrease the roughness of the EDMed part and enhance its surface properties. However, further research is necessary to ensure consistent removal of the unwanted defective layer when applying this combined method.

Summary: Electrical discharge machining (EDM) is a widely used manufacturing process for machining hard or high melting point metals. Previous attempts to remove the defective recast layer have increased process complexity, and existing EDM ECM hybrid processes have failed to understand the process mechanisms and propose methods to control removal mechanisms. This study introduces tailored electrolytic-dielectrics to eliminate the defective recast layer while maintaining machining rate.

Summary: The study reveals the surface-initiated rolling contact fatigue (RCF) failure mechanism under heavy load and initial high roughness surface. The results indicate that precursor of collapsed morphology and nanocrystalline layer are the main factors causing lower RCF life with high roughness compared to low roughness surfaces. The spalling failure initiating from low roughness surface under heavy load is strongly dependent on surface plastic deformation.

Summary: This study investigates the competitive relationship between fretting fatigue and plain fatigue in press-fitted railway axles. By changing the depth of the stress relief groove, the plain fatigue limit and fretting fatigue strength were tested. Detailed information was gathered, and an evaluation methodology integrating finite element simulation and the Modified Wohler Curve Method was established. The study concludes that the optimal groove depth, which balances the anti-fatigue capabilities, depends on the number of test cycles.
