TL;DR: In this paper, the authors introduced three subprocesses of the spray forming process: melt atomization, spray evolution, and droplet deposition, and discussed the basic features of the process.
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, eg, 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

TL;DR: In this article, a mathematical model was proposed to simulate the growing profile of billet during spray forming, which included some process parameters which relate to the shape profile such as nozzle data, eccentric distance, rotation speed, withdraw speed and so on.
Abstract: The parameters of atomizer were obtained from the experiment. Based on the obtained parameters, a mathematical model was proposed to simulate the growing profile of billet during spray forming. The model included some process parameters which relate to the shape profile such as nozzle data, eccentric distance, rotation speed, withdraw speed and so on. After being compared with the billet shape of experiment, we got good consistent results between the simulation and experiment, it was found that the results of the simulation is in good consistent with that of the experiment.

07 May 2003TL;DR: In this paper, a flat fan-shaped spray pattern is used to form articles from a polyurethane composition, where repeated passes of the nozzle that partially overlap apply a deposit in a series of parallel paths.
Abstract: A method of spray forming articles with a nozzle that sprays in a flat fan-shaped spray pattern. The process may be used to form articles from a polyurethane composition. Repeated passes of the nozzle that partially overlap apply a deposit in a series of parallel paths. A primary flat fan-shaped spray is flanked by a pair of secondary sprays that are outboard of the primary spray. The secondary sprays facilitate feathering the edges of adjacent deposits and provide a spray application having a consistent thickness.

TL;DR: In this paper, the structure and mechanical properties of Kh12 and R2AM5F2NYu tool steels and ZChKh25 cast iron produced by gas spray forming were studied.
Abstract: The paper studies the structure and mechanical properties of Kh12 and R2AM5F2NYu tool steels and ZChKh25 cast iron produced by gas spray forming It is shown that rapid solidification during spray forming changes not only the structural type but also the class of materials and substantially improves deformability and mechanical properties Billets from wear-resistant cast iron formed by spraying can be deformed by hot forging, stamping, and rolling with strain to 30%
