Solidification in Spray Forming
TL;DR: In this paper, a simple numerical model for the spray-formed grain size arising from the deposition of the various droplets in the spray and combines insights provided by the model with previous investigations of the phenomena occurring during and immediately after deposition to propose a comprehensive description of the important solidification behavior during spray forming.

Weidong Cai,Enrique J. Lavernia +1 more
TL;DR: In this paper, a porosity model based on particle packing theory, fluid mechanics, and particle thermal and dynamic behavior during spray forming was developed, and the amount of porosity in as-deposited materials can be estimated on the basis of the average fraction of solid in the incident spray and the solid particle packing density.

On the evolution of porosity in spray-deposited tool steels
TL;DR: In this article, the relationship between porosity and spray distance was studied using three different spray distances together with a ceramic substrate and showed that the optimum parameters correspond to a 178mm deposition distance, in the case of a porosity-rich substrate.
