Ferrite Noise-cancelling Magnetic Head Core Vacuum Sintering
Ferrite silencing magnetic head core is one of the magnetic core materials for making AC silencing magnetic head at home and abroad. Because of its small size, hard and brittle texture, high shape accuracy, and unique electromagnetic performance requirements, there is no designated factory in Chi...
Hard Magnetic Alloy Vacuum Sintering
Most of the parts made of hard magnetic alloys are formed by powder metallurgy, and then solution treatment or annealing is carried out. Therefore, the heat treatment of hard magnetic material workpieces is mainly vacuum sintering, vacuum solution treatment and vacuum annealing. Due to the strict...
Annealing of Large Silicon Steel Laminated Cores and Silicon Steel Strip Wound Cores
Silicon steel is steel with a silicon content of 0.8% to 4.8%. In the transformer manufacturing industry, a large number of iron cores made of silicon steel (usually containing 2.8% to 4.8% of silicon) are used as the magnetic conductive components of the transformer. When the transformer is work...
Preparation technology of boron carbide ceramics
Boron carbide is a new type of non-oxidized ceramic material, which is widely used in energy, military, nuclear and bulletproof fields due to its high melting point, high hardness, low density, good thermal stability, strong resistance to chemical erosion and strong neutron absorption. Boron carb...
Vacuum Heat Treatment of Thread Rolling Wheel
The thread rolling wheel is an external thread rolling tool. In the thread cutting tool and standard parts manufacturer, the thread rolling wheel is a key tool and an important tool in the production process. Its life and quality directly affect the accuracy of the processed taps, standard parts ...
Effect of Vacuum Heat Treatment on Chromium in Stainless Steel
Stainless Steel (Stainless Steel) is defined in GB/T20878-2007 as a steel with stainless steel and corrosion resistance as its main characteristics, with a chromium content of at least 10.5% and a carbon content of no more than 1.2%. It is widely used in construction, household appliances, kitche...
Pretreatment of Superalloy Vacuum Brazing
Superalloy refers to high alloyed shackle-based, drill-based or iron-based austenitic metal materials that can resist oxidation or corrosion above 600 °C, can work for a long time under certain stress, and have surface stability. The key material for the hot end components of aerospace engines is...
Advantages of Vacuum Quenching in Bearing Manufacturing
The high-temperature bearing was originally heated by a salt furnace. Due to the large salt spray when the salt furnace is heated, it will not only cause corrosion of the equipment, but also damage the health of the body and pollute the air. More importantly, the product quality cannot be guarant...
Application of Vacuum Carburizing
Vacuum carburizing refers to a process of gas carburizing under the condition of less than one atmospheric pressure. In 1950, the United States began to study vacuum carburizing and applied for a patent in 1960. In 1972, Hayes CO. published the vacuum carburizing technology. And successively deve...
Single Layer Diamond Vacuum Brazing
Compared with single-layer electroplated diamond tools, brazed single-layer diamond tools have become a hot research field of superhard material tools in recent years due to high diamond edge, large chip space, and high bonding strength between diamond and matrix. Hard and brittle materials, such...
