Coatings Free Full-Text Effect of Different Milling Media

2020年9月19日 This study investigated the effect of three different ball materials on the metal-based carbon nanotube (CNT) composites used as surface coatings on metal-powder to fabricate high-quality nanocomposites. The effect of ball material, different rotation speeds, and milling times on the coating characteristics of the metal-based high impact energy at collisions with the grinding balls and the mill pot wall. The impact energy can vary depending strongly on the milling conditions and lead to breakage of particles, resulting in decreasing the particle size and increasing the number of particles. Therefore, the impact energy alters the produced particle properties,Particle Impact Energy Variation with the Size and \n \n mesin dari raw mill \n.
