    Influence of Cold, Warm and Plasma Sprayed Layers on High-Cycle Fatigue Properties of Steel Specimens

  • Original language description

    In the presented study, the influence of thermally sprayed coatings on fatigue behavior of coated bodies was studied. Commercial-grade titanium powder was deposited onto steel specimens using four thermal spray technologies: plasma spray, low-pressure and portable cold spray, respectively, and warm spray. The specimens were then subjected to strain controlled cyclic bending test in a dedicated in-house built device. The crack propagation was monitored by observing the changes in the resonance frequencyof the samples. A stop-condition corresponding to approximately 40-60% specimen cross-section damage was used to define the fatigue performance of the specimen. The corresponding number of cycles was considered the main performance indicator. It was found that the grit-blasting procedure did not alter the fatigue properties of the steel specimens considerably (5% increase), while deposition of the coatings via all technologies significantly increased the measured fatigue lives.
