cooling heat dissipation AIN aluminum nitride ceramic plate
Reputation depends on quality, quality comes from Hard!
Aluninum Nitride Ceramic:
The matrix of aluminum nitride ceramic is austenite or martensite, and the commonly used grades of precipitation hardening stainless steel are 04Cr13Ni8Mo2Al and so on. Stainless steel that can be hardened (strengthened) by precipitation hardening (also known as age hardening). High strength, but poor plasticity and weldability. The commonly used grades of martensitic stainless steel are 1Cr13, 3Cr13, etc. Because of the higher carbon content, it has higher strength, hardness and wear resistance, but the corrosion resistance is slightly worse. It is used for higher mechanical properties and corrosion resistance. Some general parts are required, such as springs, steam turbine blades, hydraulic valves, etc. This type of steel is used after quenching and tempering. Annealing is required after forging and stamping. Special stainless steel for pressure vessels has clear requirements for its classification and code, size, shape and allowable deviations, technical requirements, test methods, inspection rules, packaging, markings and product quality certificates. Commonly used brands are 06Cr19Ni10, 022Cr17Ni12Mo2. The digital codes are: S30408, S31603, etc. Mainly used in sanitary equipment such as food machinery and pharmaceutical machinery. Different product uses have different requirements for welding performance. A class of tableware generally does not require welding performance, even including some pot companies. However, most products require good welding performance of raw materials, such as Class II tableware, thermos cups, steel pipes, water heaters, and water dispensers. Most stainless steel products require good corrosion resistance, such as Class I and II tableware, kitchen utensils, water heaters, drinking fountains, etc. Some foreign merchants also conduct corrosion resistance tests on the products: use NACL aqueous solution to heat to boiling, and then pour after a period of time Discard the solution, wash and dry, and weigh the weight loss to determine the degree of corrosion (note: when the product is polished, the abrasive cloth or sandpaper contains Fe components, which will cause rust spots on the surface during testing)
Aluminum nitride has high hardness and exceeds traditional alumina. It is a new type of wear-resistant ceramic material, but it can only be used for severely worn parts due to its high cost.
Using AIN ceramics for heat resistance, melt erosion and thermal shock resistance, GaAs crystal crucible, Al evaporating dish, magnetic fluid power generation device and high temperature turbine corrosion resistant parts can be fabricated, and its optical properties can be used as an infrared window. The aluminum nitride film can be made into a high frequency piezoelectric element, a very large scale integrated circuit substrate, or the like.
Aluminum nitride heat-resistant, resistant to molten metal erosion, stable to acid, but easy to be eroded in alkaline solution. The AIN fresh surface is exposed to moist air and reacts to form a very thin oxide film. By utilizing this property, it can be used as a crucible and a die-casting mold material for smelting metals such as aluminum, copper, silver, and lead. AIN ceramics have good metallization properties and can be widely used in the electronics industry as an alternative to toxic cerium oxide.
