Aluninum Nitride Ceramic:
When aluminum nitride ceramic welders start an arc on a metal surface, they can cause surface roughness defects. The protective film is damaged, leaving a potential source of corrosion. The welder should start the arc on the welded bead or on the side of the weld joint. Then melt the pilot arc trace into the weld. Welding spatter has a lot to do with the welding process. For example: GTAM (Gas Tungsten Arc Welding) or TIG (Inert Gas Tungsten Arc Welding) has no spatter. However, when using GMAW (gas shielded metal arc welding) and FCAW (arc welding with flux core) two welding processes, if the welding parameters are used improperly, it will cause a lot of spatter. When this happens, the parameters must be adjusted. If you want to solve the problem of welding spatter, spray anti-splash agent should be applied to each side of the joint before welding, which can eliminate the adhesion of spatter. After welding, this kind of anti-splash agent and various spatters can be easily cleaned up without damaging the surface or causing slight damage. The welding process using flux includes manual welding, flux-cored arc welding and submerged arc welding. These welding processes will leave small flux particles on the surface, which cannot be removed by ordinary cleaning methods. These particles will be the source of crevice corrosion, and mechanical cleaning methods must be used to remove these residual fluxes. Welding defects such as undercut, incomplete penetration, dense pores and cracks not only reduce the firmness of the joint, but also become a source of crevice corrosion. To improve this result, when cleaning operations, they also entrain solid particles. These defects can be repaired by re-welding or re-welding after grinding.
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.
