• What is sputtering target?

  Magnetron sputtering coating is a new physical gas phase coating method, which is to use the electron gun system to emit electrons and focus on the coated material, so that the sputtering atoms follow the momentum conversion principle to fly away from the material with a high kinetic energy to the substrate deposition film. This plated material is called the sputtering target.

• Zirconium diboride ceramic-the utility model relates to an ultra-high temperature structural ceramic material

  Zirconium boride​ is a common material in borides, and there are three kinds of zirconium boride in the boron-zirconium system, respectively, zirconium monoboride (ZrB), zirconium diboride (ZrB2) and zirconium twelve boride (ZrB12). However, due to the good stability of zirconium diboride in a wide temperature range, So the industrial production of zirconium boride is mostly zirconium diboride as the main component.

• What is chemical vapor deposition (CVD)?

  What are the main advantages and disadvantages of CVD? CVD uses one or more gases to chemically react on a heated solid substrate and to coat it with a solid film. Advantages: 1. Vacuum degree requirements are not high, even do not need vacuum, such as hot spray coating; 2. Rapid deposition rate, atmospheric CVD can reach 1μm/min; 3. Compared with PVD. Chemical composition or alloy coating is easier to achieve;
