We investigated the effect of the raw powder properties of carbon nanotube surface coatings on metal powder,with the goal of obtaining high-quality *** mechanical dry coating technique was used to fabricate CNT coatings (guest particles)on the surface of copper (Cu,host)particles using a traditional ball mill and a stirred ball *** coatings were produced under various experimental conditions (varying rotation speed and grinding duration,with a ball diameter of 5mm),and the effect of these conditions on the surface of the powder was *** coated surfaces were characterized using scanning electron microscopy and field emission scanning electron *** compared prolonged milling (48h)at a low rotation speed (50rpm),with a short milling period (12h)at high rotation *** found that for the TBM,successful CNT coating was achieved at 50rpm over 48h. In contrast,for the SBM,CNT coatings were obtained after a short milling period (12h)at low rotation speed (50rpm).

In this study,the particle morphology,and size changes in copper and iron powders were investigated by using a high-energy ball mill under the same experimental *** particle sizes and morphologies of the powders were examined using a particle size analyzer and scanning electron microscopy(SEM).We also used the discrete element method(DEM)to analyze the ball impaction and the shear energy during the ball milling *** was discovered that the quantity of milling balls and rotational speed had a major impact on energy dissipation through heat and plastic deformation as well as milling *** characteristic(particle morphology and size)of the iron and copper powder were differently changed under the same experimental conditions,shear energy,and ball *** the particle sizes of copper and iron powder were compared under the same experimental conditions,the copper particle size increased from 21.6μm to 280μm,resulting in particle agglomeration,while the iron powder particle size decreased from 154μm to 4.35μm.

Characteristics of spherical particles on copper powder and changing sizes were studied in a ball mill under various experimental conditions,such as different ball diameters,high rotation speeds,and milling times,using a discrete element method(DEM)*** experiment has investigated the characteristics of spherical particle morphology evolution involved in the mechanical alloying of copper *** morphological evolution of the copper particle was analyzed using scanning electron microscopy(SEM).A spherical copper particle was shown with a roundness value using imageJ *** DEM was used to simulate the ball motion in a planetary ball mill,and the impact energy and shear energy generated during the collision were analyzed to estimate the contact number between the ball and the ball ***,as the size of the ball decreased,the number of ball-to-ball and ball-to-wall contacts increased accordingly,and the spherical shape of the copper powder changed.
