From mass production to laboratory applicative research, when it comes to vacuum sintering, a number of questions can arise. I mean, doubts regarding the thermal insulation, the gas fluxing, loading and unloading operations, and so on. In this second part, I will try to solve any doubt you may have related to hot zone for vacuum sintering furnaces, the distribution of gas flow, and the use of furnace box for loading and unloading sintered parts and components.

Several industries rely on sintered parts and components including automotive, medical, and tools. Vacuum sintering produces consistent, bright parts with no seams, joints, or fillers. Beginning with an overview of the benefits of sintering in a vacuum, the article focuses on debinding, with regard to the decision-making process for performing or not debinding and sintering in the same furnace.

Advanced engineering components require not only better materials but also new joining or welding processes. Recently, diffusion bonding has become a viable process in the fabrication of structural hardware or fluid and gas flow devices for aerospace and electronic industries. This technology heats and applies pressure on joint materials and uses molecular diffusion to bond them. This means that the resulting joint has properties similar or equal to the parent materials. The process has the ability to produce high quality titanium joints so that neither metallurgical discontinuities nor porosity exist across the interface.
