TLDR
In this paper, a summary of the actual knowledge in plasma spraying with an emphasis on the points where work is still in progress is presented, including: the plasma torches with the resulting plasma jets and their interactions with the surrounding environment, powder injection with the heat, momentum and mass transfers between particles and first plasma jets, the particles flattening and solidification, forming splats which then layer to form the coating.Abstract:
This article intends to summarize our actual knowledge in plasma spraying with an emphasis on the points where work is still in progress. It presents successively: the plasma torches with the resulting plasma jets and their interactions with the surrounding environment; the powder injection with the heat, momentum and mass transfers between particles and first plasma jets and then plasma plume; the particles flattening and solidification, forming splats which then layer to form the coating; the latest developments related to the production of plasma sprayed finely structured coatings.read more

Particle dynamics and particle heat and mass transfer in thermal plasmas. Part I. The motion of a single particle without thermal effects
Emil Pfender,Yung-Cheng Lee +1 more
TL;DR: In this article, the relative importance of various effects on particle motion was assessed in the context of thermal plasma processing of materials, and the results indicated that the correction term required for the viscous drag coefficient due to strongly varying properties is the most important factor; non-continuum effects are important for smaller particles and/or reduced pressures.
