The mechanical properties and deadhesive properties of sol-gel coatings.

Current research involves mechanical properties and deadhesion of sol-gel coatings on metal and glass substrates.
-gel coating is considered an easy-to-use method for organic/inorganic hybrid coatings. In addition, the application of film through this technology is inexpensive and can be applied without restriction to large substrates

.
In this case, a thin sol-gel coating based on three alkyl silane mixtures is applied to the metal and glass substrates, which are synthesized in a pure water phase, have different thicknesses, and there are or do not exist ZrO 2 nanometer particles. After coating and curing, the mechanical properties of the sol-gel coating are indicated by Berkovich nano-indentation with continuous stiffness measurement mode (CSM). The effective elastic mould and hardness values of each coating are estimated along the depth of indentation, based on substrate and sol-gel properties. The effect of de-ignition at higher temperatures is also studied.
careful microscope observation
and then studied the damage pattern of the sol-gel coating using Berkovich nano-indentation technology and nano scratch technology with a radius of 5 m of spherical diamond tip. If you look closely at the remaining marks and residual grooves under a thick coating, especially on a glass substrate, there will be fragmentation and no serious malfunctions when thin coatings are applied to both substrates.
, the results show that the presence and heat treatment of nanoparticles greatly affect the mechanical properties of the sol gel and the mechanical stability of the coating on the substrate.
