Original Abstract

In the contribution, the effect of various surface treatments on appearance of fracture surfaces and micromechanisms involved in the fracture process under bending, torsion and combined bending-torsion fatigue loading is discussed based on microscopical and 3D topographical observations and measurements. The studied materials include nitrided steel specimens featuring an inner fish-eye type of fracture and nickel-base superalloy specimens with protective diffusion and thermal barrier high-temperature coatings, for which the room-temperature failures approximate those following the shutdown of the engine.
