Introduction to BAM AluminiumMgB14 powder Magnesium aluminum boride Oder Al3Mg3B56 The common name for this is BAM It is composed of aluminum, magnesium and boron. The nominal molecular formula of this compound is AlMgB14 The chemical composition of the molecule is similar to Al0.75Mg0.75B14 .
It’s a ceramic alloy that has very high wear resistance.
BAM, first described in 1970, has an orthogonal construction with four B12 units each cell. It has an equivalent coefficient of thermal extension to concrete and steel.

The Physical and Chemical Properties of the BAM AlMgB14 Pulp
Super-hard materials tend to have simple crystal structures that are highly symmetrical such as sphalerite and diamond cubes. BAM has 64 atoms per cells, but a complicated, low-symmetry crystal structure. It is an orthogonal crystal cell with four boron-containing, icosahedrons as its main feature. Each icosahedron is composed of 12 boron anatoms. The icosahedron is connected to other elements by eight additional boron-atoms. Although the occupancy of metal sites within the lattice in this material is lower than 1 it is often identified with the molecular formula AlMgB14. Its chemical composition, however, is close to Al 0.75Mg 0.75B14. This is common with borides. For boron-rich metallics, see Boride and Borodiide Crystal Structures. BAM cell parameters include a= 1.0313 nm and B =0.8115 nm. C = 0.58488 nm. Z = 4 (4 structural units per cell), spacegroup Imma, Pearson symbol OI68 and density 2.59g/cm3. The melting point can be roughly calculated at 2000°C.

BAM is able to achieve a bandgap value of 1.5 eV. Reactivity depends on the purity of your sample and can be as low as 104Ohm*cm. This coefficient of Seebeck is high at between -5.8 and -8.0 mV/K. This occurs because electrons are transferred from metal atoms onto the boron Icosahedron. This makes thermoelectric devices more efficient.

The hardness of fracture hardiness
BAM powders are microhardened to 32-35GPa. You can increase it to 45GPa using boron rich titanium alloy nitrization. Also, the fracture toughness of BAM powders can be improved with TiB2 or deposition of quasiamorphous BAM films. It will lose its hardness if you add AlN and TiC to the BAM. BAM can be defined as super-hard if it has a hardness value above 40GPa. BAM-TiB2 Composites are characterized by a 60% TiB2 content. This is the highest level of hardness and toughness. In order to increase the wear rate, TiB 2 content was increased from 60-80% to 70-80%. However, this resulted in a 10% reduction in hardness. With a hardness range of 28 to 35gpa, titanium B2 is an extremely wear-resistant additive.

Thermal expansion
AlMgB14’s thermal extension coefficient (TEC, also known by thermal expansion coefficient, COTE), was 9 x (10-6) (K-1), using expansion and synchrotron radiation high-temperature X–ray diffraction. This COTE is comparable to that of steel, titanium, or concrete. Based on AlMgB14’s reported hardness value, and the materials used to make the wear-resistant coat, AlMgB14’s COTE can be used in order to assess the method of coating and the results of the finished parts.

BAM and TiB2 are combined in a 70 % volume of TiB2 and have one of the lowest friction coefficients. They range from 0.04 to 0.05 in dry scraping of diamond tips, and 0.02 to 0.02 for water glycol-based Lubricants.

BAM AlMgB14 Pulp Application
BAM can be purchased commercially and the company is currently exploring potential uses.
Pump blades can have their pistons or seals coated with BAM/BAM + TiB2 in order to decrease friction and improve wear resistance. Reduced friction means less energy consumption. It is possible to coat cutting tools with BAM. This will decrease the amount of force necessary to cut an object, prolong tool life, and increase cutting speed. A coating of 2-3 microns thickness has been proven to increase tool efficiency, reduce wear and improve cutter performance.
