“…One of the most critical phases in obtaining a good bond when using adhesives is the surface preparation of the substrates. Because of this, it is necessary to ensure a very good contact between the adhesive and the adherent by modifying the latter's surface [18,19].…”

Surface modification by different technologies prior to joining operations or improving tribological properties is a point of great interest. Improving surface activation by increasing the roughness of the metal is a relationship that is becoming more defined. In turn, an increase in surface wettability by evaluating contact angles indicates surface activation by obtaining a high surface free energy. Technologies such as shot blasting and laser surface texturing (LST) have generated several scientific studies where they have identified the influence of parameters on the formation of rough surfaces with defined patterns. However, the application of abrasive water jet texturing (AWJT) has been little studied as an alternative. This article compares these technologies in the texturing of a carbon steel s275 in order to identify the relationship between surface quality and surface activation. It has been determined that AWJT produces the highest Rt values close to 64 µm with a cross feed of 0.45 mm and a traverse speed of 5000 mm/min. Furthermore, LST obtains the best values of free surface energy by combining a power of 20 W with a frequency of 20 kHz and a sweeping speed of 10 mm/s. Finally, contour diagrams have been obtained which relate these variables to the texturing parameters.

“…Wettability measurements revealed the physical properties of materials related to their adhesion to the surrounding media. Such materials have high surface free energy, as a large amount of energy is released when it is dissociated into smaller pieces [31]. Wettability is related to the surface free energy involving the measurement of contact angles as the primary data, which indicates the degree of wetting when a solid and liquid interact.…”

The Synergistic Effect of the Laser Beam on the Thermionic Vacuum Arc Method for Titanium-Doped Chromium Thin Film Deposition

Laser-Induced Thermionic Vacuum Arc (LTVA) provides a better way to produce uniform metallic thin films than the classical Thermionic Vacuum Arc (TVA) method. In Ti-doped chromium thin films produced using LTVA, the amorphous chromium is superimposed with small bcc chromium nanoparticles. These amorphous/crystalline structures with small crystallites induce lower roughness and electrical resistivity, reducing electron–phonon scattering and increasing charge transport across LTVA thin films. A significant shift in resistivity for the LTVA samples is observed due to electron scattering on the phonon–crystalline structures in the TVA samples which exhibit larger crystallites. Meanwhile, the wettability measurements reveal a higher contact angle, resulting in a lower surface free energy and consecutively lower dissociation energy for the LTVA-produced thin films than the TVA samples.

“…Some of the most important parameters which have been studied mostly are: adhesive line length, [6][7][8] tapering end of adherend, [9][10][11] the thickness of the adherend materials, 6,[12][13][14][15] adhesive thickness, 6,18 strength and elastic modulus of the adherend material, [15][16][17][18] strength and elastic modulus of the adhesive element, 8,19 adhesive type, 20 and adherend material type, 21 different surface roughness and removal of unnecessary layers from the bonded surface by grinding, [22][23][24][25][26] cleaning or degreasing the surface in an acidic or alkaline bath, coating the surface with primers to form a new active layer, etching, corona treatment, plasma treatment to change the surface activity. 27,28,37 Additionally, several types of lap configurations have been developed that minimize stress concentrations in adhesive joints. 29 Because single lap joint is a common type of connection used by many researchers due to the rapid availability of the test results, [30][31][32] in this paper, sigle lap joint (SLJ) has been applied as overlap type and the parameters of the adhesive thickness and coating type's impact on fatigue analysis were examined.…”

Adhesive technology defined as a kind of chemical bonding alternative to thermal and mechanical joints, has attracted the attention of industry people and researchers in various fields, especially in the automobile sector for the last 30 years. Therefore, this research study has aimed to consider the issue in the automotive industry, the adhesion performance was investigated for the cases in which a metal part was joined to a vehicle body both after applying coatings and primer paint respectively. İn this respect, some of the test samples were prepared by being coated with cataphoresis, while some others were produced with primer painting along with the ones that do not have any coating or painting on them. Following this procedure, single lap type joints with different adhesive thicknesses were manufactured and subjected to fatigue tests. To make a comparison of their fatigue endurances, spot welded joints, as an alternative bonding method, were also subjected to the fatigue test. It was clearly observed that the spot welding joints have surpassed their adhesive counterparts in fatigue performance, and the samples coated with cataphoresis have outperformed among the adhesion type bonds.
