Introduction High hardness and high strength cutting materials, such as hardened steel, have become an important research topic in industry and academia.
One type of cutting tool suitable for difficult materials is ceramic cutting tool.
Yi et al [21] prepared self-lubricating ceramic materials with nano-calcium fluoride (CaF2) as solid lubricant by vacuum hot pressing process.

The development of functional materials PEM has been focused a lot on organic-inorganic hybrid materials that blend the properties of the two components [17].
Biopolymer matrixes are often filled with inorganic materials as support.
Materials studies on polymer electrolytes membrane including filler usually utilize heteropoly acid or inorganic material with highly delocalized electrons in the anion.

These materials began to exhibit extensive PWSCC at increasing rates in the early 1970s.
Subsequently, PWSCC was observed in more experiments; these early tests were conducted with wrought materials.
Subsequently, the SCC of Alloy 600 welding materials (e.g.
Wrought materials have generally equiaxed shapes of grains.
