Appears along the edge of the pressure block, and is at a certain angle to the pressure surface, forming a neat interface called delamination. If the cobalt content of the mixture is low, the carbide hardness is high, the powder or granules are finer, the forming agent is too small or unevenly distributed, the mixture is too wet or too dry, the pressing pressure is too large, and the unit weight is too large. Layered. Improving the strength of the briquettes, reducing the internal stress and elastic aftereffect of the briquettes are effective methods to solve the delamination.
Want to be applied to high-performance, high-precision CNC machine tools, while achieving stability and better processing efficiency, generally put forward higher requirements than ordinary tools for carbide CNC tools from design to manufacturing and use.
Molybdenum is a metallic, silvery-white element which is very stable chemically but it will react with acids. The physical characteristic that makes molybdenum unique is that it has a very high melting point, 4,730 degrees Fahrenheit. This is 2,000 degrees higher than the melting point of steel.
Compared with traditional electrode materials, tungsten-based electrode materials have the characteristics of high melting point, good corrosion resistance, high density, and superior thermal and electrical conductivity, so they are widely used in the field of welding.
In order to avoid environmental pollution caused by military materials, tungsten alloy military products are gradually replacing lead and depleted uranium for bullets and armor-piercing bullets. In the military field, tungsten alloy military products are gradually becoming popular.
Nuclear batteries are also called "radioisotope batteries", or isotope batteries for short. It uses semiconductor transducers to convert the heat energy continuously released by radioisotopes in the decay process into electrical energy.
China tungsten price was in the upward trend in the week ended on Friday July 31, 2020, but affected by the weakness both in the supply and demand sides, transactions were poor at the end of this month.
The international research team conducted characteristic research and analysis of the "cobalt/molybdenum disulfide heterostructure" and found that this new material combination is expected to lead semiconductors to break through the physical limits and become a potential new star.
