Surface Layer Analysis after Shot Peening by Barkhausen Noise Signal
In the paper there will be introduced method for relative determination of induced kinetic energy of hardened balls on treated surface, which was invented by J. Alemen. In our experimental work we were focused on measuring Barkhausen noise signals and comparison with microstructure, microhardness, and residual stress analysis of surface roughness. In process of shot peening there is occurrence ...
متن کاملEffect of Shot Peening Treatment on Forging Die Life
The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...
متن کاملEffect of Residual Stresses on Fatigue Strength of Severely Surface Deformed Steels by Shot Peening
The compressive stress distribution below the specimen surface of severely surface deformed steels by shot peening was investigated by using laboratory X-rays and high-energy X-rays from a synchrotron radiation source, SPring-8 in the Japan Synchrotron Radiation Research Institute. Medium carbon steel plates were heat treated in two different conditions. The Vickers hardness of material-A and B...
متن کاملIncreased osteoblast function in vitro and in vivo through surface nanostructuring by ultrasonic shot peening
Surface topography has significant influence on good and fast osseointegration of biomedical implants. In this work, ultrasonic shot peening was conducted to modify titanium to produce nanograined (NG) surface. Its ability to induce new bone formation was evaluated using an in vivo animal model. We demonstrated that the NG surface enhanced osteoblast adhesion, proliferation, differentiation, an...
متن کاملCorrosion Properties of 34CrMo4 Steel Modified by Shot Peening
A nanocrystalline layer was prepared on the surface of 34CrMo4 steel by time controlling shot peening (SP, i.e., 1, 5, 10, and 20 minutes). Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) analysis, and transmission electron microscope (TEM) were applied to analyze the surface, cross-sections, and grain size of the specimens before and after SP. The electrochemical c...
