The aim of the paper is to investigate the effect of size of multiwalled carbon nanotubes (MWCNTs) as additives for dispersion in gear oil to improve the tribological properties. Since long pristine MWCNTs tend to form clusters compromising dispersion stability, they are mildly processed in a ball mill to shorten the length and stabilized with a surfactant before …

Ball Milling. Ball milling is a method that is usually used to grind bulk materials into fine powder. During milling, a high pressure is generated locally due to the collision between the rigid balls in a sealed container (Fig. 5). Cascading effect of …

Multi-walled carbon nanotube (MWCNT) with various weight percentage 0.5, 1.0, 1.5 and 2.0 were added as a reinforcement to aluminium (Al) matrix. A planetary ball mill was used for mechanical alloying and even dispersion of carbon nanotubes (CNTs) in aluminium matrix. Tin (Sn) with 1.0 weight percent was used in composite to incite the sintering.

graphite particles and the ball mill used and friction force [1]. The milling process is described as a kinetic process where there is a transfer of kinetic energy to collisions between the ball mill and graphite. Ball mill is assumed to move free fall at a speed equal to the speed of gravity of the earth at a certain time interval. Fig. 1.

The effects of ball milling on various properties of ground multi-wall carbon nanotubes were studied. These properties were granulometry, SEM, specific surface area, density, crystalline structure, surface chemical analysis and thermogravimetry.

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 nanocomposite were studied.

In our case, the DLS technique is selected to find out the effect of ball milling on the stability of latex particles. Fig. 1 shows the normalized number of particles vs. particle size for XSBR latex before and after being subjected to milling process. For the purpose of comparison, the results of a similar experiment carried out on the styrene–butadiene rubber (SBR) latex are …

Particles, which may include nanoparticles, are mixed with carbon nanotubes and deposited on a substrate to form a cold cathode. The particles enhance the field emission characteristics of the carbon nanotubes. An additional activation step may be performed on the deposited carbon nanotube mixture to further enhance the emission of electrons.
