Abstract

Spray forming is an advanced process route to produce near-net-shaped preforms from metallic materials. As it combines the main advantages of the classical processes of metal casting and powder metallurgy, its products are characterized by extraordinary material properties. Since the 1970s this process has been developed and it is now in its commercialization state in several applications, e.g., in the automotive and aerospace industry. Though essentially a metallurgical process, understanding and optimization is based on principles of process and chemical engineering. This is reflected by means of the three process stages as: melt atomization, spray evolution, and droplet deposition. In this contribution these three subprocesses will be introduced and basic features of the process will be discussed.
