Study of the effect of nanoclay incorporation on the rheological properties and corrosion protection by a silane layer

Effect of sonication on high temperature properties of bituminous binders reinforced with nano-additives

“…By increasing the energy input for homogenisation, either by extending sonication duration or by expanding wave amplitude, the storage modulus increases. Such an effect can be attributed to disintegration of clusters of nano-particles which makes a greater surface available for interactions and three-dimensional networking [30,31].…”

Influence of formulation and application parameters on the performances of a sol–gel/clay nanocomposite on the corrosion resistance of hot-dip galvanized steel. Part II. Effect of curing temperature and time

“…Ultrasonic treatment was performed for 2 h in a 50 ml beaker using a Hielscher UP100H sonicator with the power set to 13.5 W and controlled in temperature by using tap water circulation. A two hour long sonication treatment was proved to ensure a complete exfoliation of the montmorillonite platelets leading to hybrid films with improved protection properties [1]. The dispersion was acidified by adding HCl to accelerate the hydrolysis of the Si\OR groups.…”

“…In a previous work [1] a sol-gel/nanoclay composite coating was investigated as a protective layer for the corrosion protection of hot dip galvanized (HDG) steel. The coating showed interesting performance as a corrosion protective layer for galvanized steel.…”

Formation and characterization of Fe3+-/Cu2+-modified zirconium oxide conversion layers on zinc alloy coated steel sheets

“…Recently, new environmentally friendly pretreatment technologies have been developed. The most interesting candidates for these sophisticated surface coatings are organosilanes [2][3][4][5][6], lighter rare earth metals [7,8] and transitional metals [9], respectively. Moreover, promising alternatives are the application of zirconium containing layers on the metal surface by the solgel process [10][11][12][13] or by immersion in hexafluorozirconic acid (H 2 ZrF 6 ) conversion solution [14][15][16][17][18][19][20][21][22][23][24].…”
