Latest Patents
Deneuville holds a patent titled "Determination of adhesion strength of HVOF coating by spherical indentation." This method provides a systematic approach to assess the adhesion strength of any HVOF-coating/substrate system. The technique involves applying a spherical indentor to the coated part during a loading-unloading cycle. The substrate undergoes plastic deformation during loading, while the unloading phase reveals the elastic-plastic mismatch between the coating and substrate materials. This mismatch generates tensile stress at the interface, which can lead to delamination if the indentation load is sufficient. A hybrid numerical-experimental approach is employed to calculate interfacial adhesion, with the threshold load for delamination determined experimentally. Additionally, a finite element model is utilized to calculate the corresponding adhesion stress for delamination. This method allows for the quantitative evaluation of adhesion for any coating/substrate interface, regardless of bond strength.
