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
