In the atomization process, the melted metal alloys are first refined and degassed, then poured into a gas nozzle, where the liquid material is disintegrated into metal powder by a high-pressure gas stream. Gas atomization, water atomization and direct reduction all rely on industrial gases and gas technologies.
Which atomization method is used to atomize molten metal?
Single fluid atomization and two-fluid atomization are the two ways of atomizing the molten metal ( Apelian et al., 2017 ). One of the characteristics of the LMMCs processed by spray atomization & deposition is that, no distinct separation between the two layers of metal and MMCs can be observed. Fig. 10.
Which atomization techniques are used in layered sic P /6061 MMC?
Free-Fall Gas Atomization (FFGA), Close-Coupled Gas Atomization (CCGA), Pressure-Swirl Film Formation Plus Gas Jet Disintegration are few other forms of the two-fluid atomization techniques ( Anderson and Achelis, 2017 ). Xu et al. (1998) fabricated layered SiC p /6061 MMC using spray atomization and co-deposition.
What are the different types of atomization process configurations?
In this chapter we review the major types of atomization process configurations: free-fall gas atomization with an unconfined melt stream and close-coupled gas atomization with controlled melt introduction to an energetic gas flow. Studies will be reported of several...
2.1 Introduction
For the enhanced control of gas atomization in high temperature, high surface tension fluids (molten metals) it is preferred to use more complex two fluid nozzles, termed close-coupled gas atomization (CCGA) nozzles. As illustrated in Fig. 3.4, the atomization gas exits from a gas jets (or a gas slit) that is connected by a distribution manifold an
2.2 Discussion
It should be apparent that CCGA nozzles are capable of more energy intensive disintegration in the near-field “atomization zone” because of the closer proximity of the high energy atomization gas to the initial melt exit, compared to free-fall atomization nozzles, and, thus, should produce higher yields of fine powder. Commercial powder producers h
2.3 Control of Primary Atomization in CCGA
A grand challenge for the technology of two-fluid gas atomization of melts is to demonstrate a significant range of droplet size control based on shear velocity, which can be related to a specific melt break-up model [4]. In an attempt to gain control of the process and to limit broadening of atomized particle size distributions, close-coupled two-
2.4 Pulsatile Shock-Enhanced Disintegration in CCGA
Powder processing is an efficient manufacturing method that reduces material waste (e.g., machining scrap) during fabrication of net shape components by the die pressing and sintering approach of conventional powder metallurgy (P/M), as well as during additive manufacturing (AM) of near-final shape objects that are “built” from powders by this very
