Thus, materials with perovskite structure are the best candidature as to provide high dielectric constant.
To date, a lot of perovskite structures had been studied such as PZT, SrTiO, BaTiO [1, 2] but outstanding dielectric constant values had been reported only for CCTO which reaches up to 105 with low loss at low frequencies.

This phenomenon can be explained in terms of surface chemistry of the oxide particles in the suspension which was governed by the reaction between the oxide surface and the isopropyl alcohol medium and the adsorption of preferential ions from nitric acid.
The results show that only very small amount of Zr can be doped inside BT structure.
The addition of Zr in BT structure causes suppression of grain growth.

This could be due to a. different distribution of stresses inside the body in contact due to the difference in mechanical behavior (modulus of elasticity, super strength) and a difference in terms of physical- chemistry of the surface.
To check if this texture significantly influences the tribological behavior modeling aspects coupling fluid / structure can be considered.

When Fe3O4 and Na2B4O7 additives are added in the boronizing agent, the structure of diffusion layer will change from columnar to lath-shaped and the boride layer becomes thinner.
Additives can change the structure and thickness of diffusion layer and wear resistance property.
