The company aims at diesel engine for motorcycle, automobile and ships.
The processing includes rough and finish milling of the cams, the finish turning of journals, drilling the oil hole on the journals, finish turning of flange and the drilling, broaching and reaming of flange holes.
It’s a kind of compound of nitrogen and boron, the hardness of which is second to diamond.
It can stand temperature as high as 1300℃ to 1500℃ and its thermal conductivity is 45 times of corundum, which is extremely suitable for high strength alloy steel while leave no flaw in the cutting tool.

The 70s represent the “golden age” of prefabricated 3D lattice structures [6], that nowadays are finding a new impetus for the construction of complex geometries made of steel or aluminium alloys [7, 8], which are used in the civil field for the construction of large roofing and towers [9] or in the industrial one for automotive, lifting and offshore applications.

Metallic alloys (e.g. titanium, aluminium), polymers (e.g. polyglycolic, polylactide), biopolymers (e.g. silk fibroin), hydroxyapatite and phosphate-based ceramics are examples of the available synthetic materials which can be used in biocomposites[21, 22].
Metallic alloys, such as stainless steel and titanium, can provide satisfactory load bearing properties, and are widely used in fracture surgery due to the ease of handling, relatively low cost, and availability.
Calcium phosphate compounds are osteoconductive and biocompatible and can be used alone.
Generally, the shells are heated to 900 ͦC to remove organic compounds and to convert calcium carbonate to calcium oxide, which upon contact with atmosphere is turned to calcium oxide.
Regarding the phosphate sources, Boonyang et al. (2101) compared three different phosphate precursors (NH4)2HPO4, Ca3(PO4)2, and H3PO4) and only (NH4)2HPO4 and Ca3(PO4)2were reported as suitable compounds for the production of monophasic HA [117, 118].

The ability of certain compounds to quickly transform electromagnetic energy into heat is quite different from the usual heating processes via conduction, irradiation or convection [66, 67].
Many papers can be found in the literature aiming at the purification of water using SPM NPs [163-165].

The high temperatures and huge heat release in SHS process allow to achieve the effective synthesis, sintering and structure formation of refractory compounds, such as corundum, mullite-corundum, spineles, carbides, and others.
The remand in the mentioned above refractories steadily increases owing to the growth of need for production of metallurgy and intensification of processing metals and alloys, toughening of requirements to the quality of the products being obtained.
Of interest is the fact that chromium oxide CrO3 - a toxic compound – is absent in over-carbonized products.
This results in a composite material framed with mineral compounds such as spineles, carbides and oxides and space between them filled with carbon.

These areas are: Computational Thermodynamics and Alloy Development of Magnesium Alloys (Pennsylvania State University); Hot Tearing Behaviour of Magnesium Alloys (CANMET); Creep, Bolt Load Retention, and Microstructural Analysis of High Temperature Magnesium Alloys (University of Michigan at Ann Arbor); Evaluation of Magnesium Corrosion by Various Methodologies and Surface Composition of Magnesium Alloys by Rutherford Backscattering (Universities of Michigan at Dearborn and Ann Arbor); and Fluxless Recycling Methods and Process Control for Creep-Resistant Magnesium Alloys (Case Western Reserve University and CANMET-MTL).
In other research at CANMET, high-strength micro-alloyed alloys are being tested for use in thinwalled Mg castings.
There have been numerous investigations into this area especially with aluminum alloys.
The aim of the HSWRM Wrought Magnesium Alloy/Process Development effort is to reduce the processing cost and produce a more formable alloy.
