Effect of Particles Concentration on the Properties and Microstructure of Ni/TiO₂ Group EMR

Abstract:

By means of mechanical properties test and microstructure observation,the relationship between mechanical properties ,microstructure graph of core-shell Ni/TiO₂ group particles concentration of EMR and different electric field, magnetic field or electric-magnetic field have been researched. It is found that with increasing of particles concentration, the properties are increased. But there is a critical range value, too high or too low particles concentrations are harmful to properties and microstructure. The best particles concentration of Ni/TiO₂ particles is about 30%. In the same field with increasing concentration, particles chain of electrorheological fluid under certain electric field become more strong,brawnier and interweaved each other.
