The unique combinations of nanocomposites make them ideal for a corrosive environment similar to that of a space environment.
Ball milling is a grinding method that grinds nanotubes into extremely fine powders. During the ball milling process, the collision between the tiny rigid balls in a concealed container will generate localized high pressure.
The GO sheets and TiAl4V powders were mixed by using a QM-3SP2 planetary ball mill (Nanjing Nanda Instrument Co., Nanjing, China) at a speed of 400 r/min, for 30 min, and the stainless steel ball had a diameter of 4 and 8 mm. Graphene oxide sheets were easily find on the SEM image, as shown in Figure1.

It is a ball milling process where a powder mixture placed in the ball mill is subjected to high-energy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960.
A custom built planetary ball mill was also used for some of the syntheses. This mill was found to perform approximately 10 times more intensive milling than Fritch P5. The milling process with both mills was carried out for different time with 1 hour of continuous milling, followed by 15 minutes relaxation time.
Abstract Mechanical alloying and mechanochemical treatment are the major powder processing techniques on the nano scale In these processes a high energy ball mill has been applied to synthesize compounds and nanocomposites such as aluminum metal matrix nanocomposite hydroxyapatite and bionanocomposites based on hydroxyapatite.
These the ball mills are used in mineral industries where along with grinding process it is also used for cold welding as well, with the purpose of producing alloy from powders[4].The mixing of powders can be compacted in a suitable hydraulic pressing unit. The specimens after the process of compaction are called as green specimen [5].
Although the process is quite efficient, it is noisy and requires a long milling and cleaning time. This may be a bad option if you're trying to create a green nanocomposites. The ball milling process can be categorized into two types: wet and dry. Wet ball milling is commonly used for processing materials with high reactivity.
The WO 3-x /PU nanocomposites were prepared by a stirred ball milling process. The ball mill used was a high-performance batch-type stirred bead mill, Pulverisette classic line (Utek International Co. Ltd., Idar-oberstein, Germany). Yttrium-stabilized zirconia (95% ZrO 2, 5% Y 2 O 3) stirred beads with a diameter of 5 mm were used.
The purpose of this work is to present a new processing technique for polymer matrix nanocomposites using a high energy mill as an effective approach to disperse ceramic nanoparticles in a polymer matrix. SiO 2 /epoxy nanocomposites were processed with various SiO 2 contents using the proposed approach.
