[1] Yabuki, A., Particle-induced damage and subsequent healing ofmaterials: Erosion, corrosion and self-healing coatings, AdvancedPowder Technology, Vol. WebIn so called smart or intelligent self-healing coatings active agents that are safely stored inside the coating are released upon onset of corrosion. The properties such as very good processability, excellent chemical resistance, good insulation against electricity, and strong adhesion to non-homogeneous materials have caused epoxy materials to be widely considered in the coating industries. Self-healing coatings are coatings that possess the internal capability to repair sustained damage by themselves, or with some outside stimulation. However, the truth is that the hardness of the coating is actually correlated with less scratch resistance. Gn vo ti khon mng x hi/gian hng trc tuyn. ; Hu, W.B. E. Shchukina, H. Wang and D. G.
