The self-healing coating is prepared on the surface of 3D-printed stainless steel by hot pressing method. When the coating is physically damaged, the self-healing intermediate layer physically repairs the damage autonomously, closing and sealing the gap and providing an active physical barrier. In contrast, NEIs self-healing coating involves physical gap closing and crack sealing, which has the potential to impart performance that matches that of a chromate-based system. Webservice life of the coating. When the coating damaged, the microcapsules release the healing agents. Other coatings self-heal through a process called auto-mechanical self-healing.
Brands tout the merits of their coatings by claiming a 9H hardness (the highest level on the pencil hardness scale). Since then, many different types of nanocontainers have been demonstrated: from polymer capsules to porous inorganic nanoparticles with sophisticated mechanisms of release triggering. If a self-healing material is scratched, you can close or fill the scratches, leaving it as if the material had never been scratched. Organic coatings are one of the most popular and powerful strategies for protecting metals against corrosion. chn lm trang bn hng online vi tn min ".vn" m khng phi l cc ui
