Abstract
The processes of oxidation that occur during particle inflight motion and d uring splat solidification in an oxygen-rich atmosphere were considered for the thermal spray process. The effect of oxidation on droplet flattening, splat-substrate mechanical and thermal interaction, splat morphology, and d evelopment of coating porosity and adhesion was studied. The influence of w etting and oxygen dissolution on flattening and splat-substrate adhesion wa s also investigated. The results from theoretical treatment agree with expe rimental observations.
