The essence of sintering is that the powder block is heated in an appropriate environment or atmosphere, and through a series of physical and chemical changes, the bonding between powder particles undergoes a qualitative change. The strength and density of the block increase rapidly, and other physical and mechanical properties are also significantly improved. The performance of ceramic materials ...

After purchasing our company's nano iron oxide powder, the customer found that the particle size was larger during testing. Why is that? Because the particle size of nano powder is very fine, it is easy to agglomerate, so the large particle size tested is the particle size after agglomeration. So how can we effectively disperse nano iron oxide powder? Next, we will introduce how to use ultrasonic ...

The major limitations on TEM performance are spherical aberration (also known as aberration), chromatic aberration, and astigmatism. The spherical aberration and chromatic aberration limit the resolution of traditional TEM. Both of these defects are inevitable when using static rotational symmetric electromagnetic fields. Ball aberration is the most important factor determining the performance of ...

High entropy alloys (HEAs) are a new type of structural material composed of five or more elements in nearly equal atomic ratios, exhibiting characteristics such as high entropy effect, lattice distortion effect, slow diffusion effect, and cocktail effect. Laser cladding technology can significantly improve the hardness, wear resistance, and corrosion resistance of HEAs cladding layers due to its ...
