Research On MAX Phase Materials

wallpapers Tech 2020-12-16
MAX phase (including Ti3SiC2, Ti2AlC, etc.) is a new machinable ceramic material that has attracted much attention.
This material includes more than fifty kinds of ternary carbides or nitrides. M represents a transition metal element; A represents a main group element; X represents carbon or nitrogen. The basic chemical formula can be expressed as M(n+1)AXn. Among them, Ti3SiC2 is the most widely studied. Ti3SiC2 was synthesized by Professor Barsoum's group of Drexel University in the United States in 1996 by hot pressing, and its excellent properties were discovered. Due to the unique nano-layered crystal structure, this type of material has properties such as self-lubricating, high toughness, and conductivity.
Such materials can be widely used as high-temperature structural materials, electrode brush materials, chemical anti-corrosion materials and high-temperature heating materials. After 1996, research related to this type of material was widely carried out in Japan, Europe and China.

The MAX phase material is a natural layered carbonitride inorganic non-metallic material composed of three elements. It has the electrical and thermal properties of metal, and also has the high strength, high temperature resistance, corrosion resistance and other harsh environment service capabilities of structural ceramics. MAX phase materials have received extensive attention in the fields of high-temperature lubrication, oxidation-resistant coatings, accident-tolerant nuclear materials, self-healing composite materials, and energy materials. Materials scientists at home and abroad are actively carrying out a large number of exploration and research.
Our country has made remarkable achievements in the fields of MAX-phase structural materials and MXene energy materials. With the development of synthesis technology and the in-depth exploration of multidisciplinary interdisciplinary, more and more domestic materials research groups have devoted themselves to the development of such novel materials. the study.
