To realize large wind power plants in an economically feasible way, it is necessary to identify potential for lightweight design of the generator hollow-shafts, which are commonly produced by casting. The weight of these shafts can significantly be reduced by producing them by open-die forging, since the forming of the material leads to a higher strength, which allows to reduce the wall thickne...

The article deals with the replacement of hard chrome plating by applying duplex system plasma nitriding + CrN coating (hereinafter referred to as PN CrN). goal research was find a suitable alternative for steel surface treatment that would replace and ensure similar mechanical tribological properties. An exposed part small-bore weapon selected evaluation, namely gas piston 42CrMo4 breech mecha...

Understanding the effect of thermomechanical loads during finish cutting processes, in our case hard milling, on surface integrity workpiece is crucial for creation defined quality characteristics high-performance components. Compared to computationally generated modifications by simulation, measurement-based determination material can only be carried out selectively and a point-by-point basis....
