“…[18][19][20][21] It has been shown by Ni 22 that overall frequency content of AE signals is almost unchanged while the amplitude is greatly attenuated with long distance propagation. Thus several studies using Short Time Fourier Transform (STFT) 23 and continuous wavelet transform (CWT) procedures 22,[24][25][26] were performed to discriminate damage mechanisms in composites. A frequency analysis using the centroid frequency (f c ), i.e.…”

“…The appropriate position of the AE sensor near the emission zone during the scratch test is of the highest importance. Small sensors can be placed on the mount of the scratching tip [75,78,79] or glued to the surface of sample [80,81]. Both solutions are often used in practice and both possess some advantages and disadvantages.…”

Abstract:The scratch test, as probably the most widespread technique for assessment of the adhesive/cohesive properties of a film-substrate system, fully depends on reliable evaluation based on assessment of critical loads for systems' failures. Traditionally used evaluation methods (depth change record and visual observation) may sometimes give misleading conclusions about the failure dynamics, especially in the case of opaque films. Therefore, there is a need for another independent evaluation technique with the potential to complete the existing approaches. The nondestructive method of acoustic emission, which detects the elastic waves emitted during film cracking and delamination, can be regarded as a convenient candidate for such a role even at nano/micro scale. The strength of the combination of microscopic observation of the residual groove and depth change record with the acoustic emission detection system proved to be a robust and reliable approach in analyzing adhesion/cohesion properties of thin films. The dynamics of the gradual damage taking place during the nano/micro scratch test revealed by the combined approach is presented for SiC and SiCN thin films. Comparison of critical load values clearly reflects the higher ability of the AE approach in detecting the initial material failure compared to the visual observation.

“…Formability and the damage resistance of Zn coating strongly depend on its adhesion to a steel substrate [4,5]. Although many methods have been developed for the assessment of adhesion strength of coatings, such as tearing-off [6,7], peelingoff [8], bending [9,10], indentation [11], scratch test [12,13], and shear [14,15], the application of the methods of tearing-off, peeling-off, bending and shear depends on the strength of glue used to bond the coating [6,16]. Another problem about the measured shear strength is that the stress at the interface is not distributed uniformly [14].…”

In this work, a methodology for the determination of the interface adhesion strength of zinc coating on TRIP steel is present. This method consists of a conventional tensile test in combination with finite element calculation. The relation between the average interface crack length and the applied tensile stress is determined on the partially delaminated coating with in-situ tensile test. The delamination process of zinc coating on steel substrate is simulated by using a two-grain finite element model with different interface adhesion strengths. By comparing the experimental observation with the finite element calculations, the interface adhesion strength is estimated. The interface adhesion strength of the zinc coating on transformation induced plasticity (TRIP) steel is found as high as 160 MPa. The influences of microstructural parameters of zinc coating including zinc grain orientation and grain size on the delamination behavior of the zinc coating are also analyzed with the finite element model.
