In this case, which is closer to the real grinding conditions, the scratches of a single grain are sequentially conducted on the same track. removed material). In most of the single-grain scratch tests, separated scratching is implemented to get knowledge about the chip removal mechanism of exactly one chipping pass.
Alumina is the most well-known and most commonly used fine ceramic material. It has the same sintered crystal body as sapphire and ruby. It has been used for decades in electrical components for its high electrical insulation, and is widely used in mechanical parts for its high strength, and corrosion- and wear-resistance.
With its outstanding features such as low machining loads and high material removal rate, ultrasonic-assisted grinding (UAG) has been generally accepted as an effective processing technique for hard and brittle materials. To improve UAG performance, the basic mechanisms of material removal need further investigation. This study …

AL2O3 Aluminium Tri Oxide – the more AL2O3, content the higher degree of calcination. Alumina balls have higher wear resistance than ordinary ceramic balls. It also keeps the purity of grinding material in ball mills. As the alumina balls have high density, it helps to reduce the grinding time, improves grinding efficiency, and saves time.
The grinding abrasives commonly used in materials preparation are silicon carbide (SiC), aluminum oxide (Al2O3), emery (Al2O3 – Fe3O4), composite ceramics and diamond. Emery paper is rarely used today in materials preparation due to its low cutting efficiency. SiC is more readily available as waterproof paper than aluminum oxide.

Alumina, commonly known as aluminium oxide (Al2O3), is an inert, odourless, white amorphous material often used in industrial ceramics. Due to its outstanding properties, alumina has contributed to a significant number of life-extending and society-enhancing applications. It is widely used in the medical field and modern warfare [1].
Al2O3 is Corundum structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Al3+ is bonded to six equivalent O2- atoms to form a mixture of corner, edge, and face-sharing AlO6 octahedra. The corner-sharing octahedra tilt angles range from 48–60°. There is three shorter (1.87 Å) and three longer (1.99 Å) Al–O bond …
