What material is TZM molybdenum alloy?
The full name of TZM molybdenum alloy is: molybdenum zirconium titanium alloy or titanium zirconium molybdenum alloy. TZM stands for T titanium (Ti), Z stands for zirconium (Zr), and M stands for molybdenum (Mo). The material contains titanium Ti0.50% and zirconium Zr0. About 10%, which makes it have the characteristics of high temperature resistance and good mechanical properties. Common specifications include plates, polished round bars, polished long square bars, rings, etc. Characteristics of TZM alloy: high melting point, high strength, high elastic modulus, small linear expansion coefficient, low vapor pressure, good electrical and thermal conductivity, strong corrosion resistance and good high temperature mechanical properties. Application: Commonly used in the electronic and electrical industry such as electron tube cathodes, grids, high-voltage rectifier components, semiconductor thin film integrated circuits, etc.; in addition, in nuclear energy equipment such as radiation covers, support frames, heat exchangers, rails, etc.

Introduction to tungsten electrode
Tungsten electrode is a tungsten electrode made of materials with high melting point, corrosion resistance, high density, good thermal conductivity and electrical conductivity. Tungsten electrode is widely used in welding due to its properties. Tungsten electrodes are ground or polished and black rods. The final colors are all different and the difference can be distinguished. In tungsten electrodes, more importantly, their final color is different, and the tungsten content is also different. When welding, choose the right tungsten electrode to make welding easier and importantly get a high quality weld. Some important factors to consider in making the right choice are the type of power source (inverter or transformer), welding material (steel, aluminum or stainless steel) and material thickness. Tungsten electrodes are used for TIG welding. They are tungsten alloy strips made by adding about 0.3%-5% of rare earth elements such as cerium, thorium, lanthanum, zirconium, yttrium, etc. into the tungsten matrix through powder metallurgy. Press machined, diameters range from 0.25 to 6.4mm, standard lengths range from 75 to 600, and the most commonly used specifications are diameters 1.0, 1.6, 2.4 and 3.2. The shape of the electrode tip is an important factor for TIG, when When using DCSP, the...

Two processes for target coating
Common coating processes include PVD (physical vapor deposition) process and CVD (chemical coating). Let’s briefly introduce these two processes. 1) PVD (Physical Vapor Deposition) process: refers to using physical methods under vacuum conditions to vaporize the surface of the material source into gaseous atoms, molecules or partially ionized into ions, and through a low-pressure gas (or plasma) process, on the matrix A technique for depositing thin films with certain special functions on the surface. The main methods of physical vapor deposition include vacuum evaporation, sputtering coating, arc plasma plating, ion plating, and molecular beam epitaxy. Up to now, physical vapor deposition technology can not only deposit metal films and alloy films, but also deposit compounds, ceramics, semiconductors, polymer films, etc. Among them, the indium tin target ITO used in display panels mainly uses vacuum coating. 2) CVD (chemical coating process) technology: This technology relies on chemical reactions at high temperatures to introduce the vapor of gaseous reagents or liquid reagents that constitute the film elements and other gases required for the reaction into the reaction chamber, and on the surface of the substrate A technology that produces thin film materials through chemical reactions. Among them, vacuum coating has better repeatability...

Comparison of white molybdenum wire and black molybdenum wire
white molybdenum wire White molybdenum wire is also called clean molybdenum wire. It uses electrolytic cleaning or hydrogen sintering cleaning method to clean the surface of molybdenum wire to remove the graphite coating on the surface. After cleaning, the surface will be bright and shiny. The diameter of the cleaning molybdenum wire ranges from 0.05 to 3mm. Its surface condition should be bright and free of oxidation, rust or spots. Its characteristics: high strength, good electrical conductivity, bright and shiny surface, fast cutting speed, long service life, etc. It is usually used for wire cutting, production of electric light source parts, electric vacuum devices, production of heating elements and refractory materials for high-temperature furnaces. In addition, it is also used as spray molybdenum wire and wear-resistant parts of automobiles to improve their mechanical wear resistance. Black molybdenum wire Black molybdenum wire is made of molybdenum wire coated with graphite coating, and its surface color is black. It is always curved or straight. In addition, it is produced through annealing. It mainly refers to a consumable made of precious metals such as molybdenum that continuously moves with a high-voltage electric field to cut the workpiece during wire cutting processing. That is,...
