The results also indicate that this system is a promising tool in seal coat surface condition evaluation, potentially aiding pavement engineers in prioritizing seal coat projects in a quantitative rather than qualitative manner.
In order to determine the influence of the surface condition, each coating was deposited on a rough (sandblasted) and a polished substrate.
However, differences in the surface-sensitivity, i.e. the dependence of coating uniformity on the substrate surface condition, of plating baths materialise when plated on irregular or improperly cleaned substrate.
The technologically most relevant properties of the oxide scales, growth rate and adherence do not only depend on the exact MCrAlY composition but also on the surface condition after coating manufacturing.
Specifically, more understanding of coating surface properties in the immersed condition, rather than in dry or in vacuo is needed, as immersion changes the dynamics of self-assembly and surface organization.
The effectiveness of tack coat in increasing shear strength may be affected by multiple factors, such as tack coat material, test condition, pavement surface condition, and moisture.
Bond strength of GFRP bars in conventional concrete depends on bar diameter, surface condition (sand coated, ribbed, helically wrapped or braided), embedment length, bar mechanical properties and environmental conditions.
In the three kinds of surface condition, the discontinuously coating has superiority for high speed cutting owing to its lifetime increasing compared with uncoated and continuously coated.
After being dried under ambient condition, the water contact angle and sliding angle on the coating surface were tested to evaluate the wettability of the coating surface.
Various structures of the as-sprayed coating surface can be observed from surface morphology of two WC-10Co4Cr coatings (Figure 4) and micro-nano coating demonstrates better melting condition, less porosity and denser microstructure than the conventional one.
The qualities of the coating surface are strongly dependent on the types of the coating materials.
