Characterization of Droplet Formation in Ultrasonic Spray Coating: Influence of Ink Formulation Using Phase Doppler Anemometry and Machine Learning

Advanced Materials Technologies, EarlyView.
This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control

Contact Fatigue Behavior of PVD‐Coated Steel [PDF]

Plasma Processes and Polymers, 2009
AbstractIn this study, the contact fatigue behavior of a PVD TiN coating deposited onto DIN 1.2379 cold‐work tool steel is assessed by cyclic spherical indentation. Experimental characterization focuses on the evaluation of critical contact pressures, under both monotonic and cyclic loading, affiliated to the emergence of distinct damage events ...

Effect of modification by Pt and manufacturing processes on the microstructure of two NiCoCrAlYTa bond coatings intended for thermal barrier system applications [PDF]

, 2010
Few studies have already shown that Pt influences the diffusion of aluminium and therefore the microstructure of β-NiAl or γ-Ni/γ′-Ni3Al materials. Besides, several works have revealed that the addition of Pt to MCrAlY (M = Ni and/or Co) improves the ...
