“…In their conclusions they state that the shear strength of the joints is proportional to the effective interfacial surface area, thereby rejecting the concept of additional mechanical interlocking. Besides mechanical testing to study the initial and residual adhesion, the scanning Kelvin probe (SKP) has shown to be a high-resolution technique for in-situ assessment of the interfacial stability for both coatings and adhesives, by measuring the corrosion potential of the buried electrode at the metal/polymer interface [8][9][10][11]. Khun and Frankel used the SKP to study the effect of surface roughness and texture on the kinetics of cathodic delamination of epoxy coated steel [12].…”

This work focuses on the effect of surface roughness, morphology and chemistry on the initial adhesion strength and corrosive de-adhesion properties of adhesive bonds. Steel surfaces are subjected to different surface pre-treatment methods such as mechanical abrasion, grit blasting, zirconium conversion treatment and silane treatment. Single-lap joint tests were performed to assess the initial bond strengths. Static wedge tests were used to study the loaded environmental ageing of joints and unloaded delamination of adhesive films from the steel surface was studied by means of scanning Kelvin probe (SKP). Experimental results indicate surface roughening plays an important role on the initial adhesion but a minor role in the durability of the bonded steel. The improved initial adhesion is mainly attributed to the increased interfacial bond area at higher surface roughness whereas complex morphology shows a more profound effect on both the initial adhesion and the durability of the interfacial adhesion. In the absence of complex texture, surfaces with altered chemistry by zirconium-or silane treatment exhibit a significant increase of the initial bonding strength and assessment of the interfacial delamination kinetics by SKP reveal that despite the absence of any surface topography, these surfaces prove to have higher resistance to delamination.

“…In terms of Scanning Kelvin Probe (SKP), it is commonly employed to determine the coating failure of poorly conductive materials instead of conductive materials by measuring the work function or Volta Contact Potential Difference (VCPD) of the material [94,95]. SKP utilizes a Kelvin probe near the surface of the specimen to form a capacitor, as shown in Figure 5 [96].…”

While global electrochemical techniques, such as Electrochemical Impedance Spectroscopy (EIS), have been utilized in corrosion and coatings research for over forty years, the refinement of those techniques into localized methods is a more recent development. In this review, in honor of Hugh Isaacs, the authors have focused on developments in localized methods of importance to corrosion research. Receiving special attention in the review are the following methods: Scanning Vibrating Electrode Technique (SVET), Localized Electrochemical Impedance Spectroscopy (LEIS), Scanning Electrochemical Microscopy (SECM), Scanning Kelvin Probe (SKP), Scanning Ion-Selective Electrode Technique (SIET), and Scanning Droplet Cell (SDC) Technique. For each method, a summary of the method along with several examples of its use in the area of corrosion and coatings are provided. Additionally, synergies with electro-microimaging techniques are discussed which highlights the often complex experimental designs required to probe the mechanisms of corrosion.
