The production of metal powder feedstock poses a challenge for many manufacturers, especially when it comes to producing high-end alloys. Key quality characteristics include high atomization rates, narrow particle size distribution (PSD), and consistent particle shape. Boron Nitride (BN) solids, with their unique combination of chemical, electrical, mechanical, and thermal properties, are ideal for applications involving molten metals. BN's inertness, low surface energy, and low friction coefficient make it stable and corrosion-resistant at high temperatures, aiding in achieving stable dimensional tolerances.
Compared to traditional zirconia nozzles, BN nozzles offer higher atomization yields, improved particle size distribution, and better control over particle shape. This is particularly important for processing difficult alloys, as poor powder quality can increase costs. Additionally, BN nozzles can reduce production downtime caused by clogging, thereby increasing production efficiency.
The application of BN in 3D printing technology is also continuously expanding. As new technologies emerge, metal powders remain the most common feedstock, and their deposition and forming technologies are evolving. The benefits of BN for metal atomization are increasingly relevant to these new 3D printing technologies. Some 3D printing manufacturers are currently seeking ways to control molten metals at high temperatures. Better process temperatures can impose significant thermal stresses on mechanical parts, leading to new challenges in printer design, such as selecting materials with the best heat resistance and negligible reactivity to molten metals. In the context of molten metal distribution, precision-machined BN nozzles can ensure consistent results. Their high thermal shock resistance and low thermal expansion coefficient enable them to withstand high thermal gradients, while their high thermal conductivity aids in the rapid solidification of metal after deposition, which is crucial for accurately controlling the 3D printing process involving molten metals.
