Microstructure, mechanical properties, and adhesion in IN625 air plasma sprayed coatings
Original language description
The effects of feed stock particle size on the microstructure and the mechanical properties of IN625 air plasma sprayed coatings were investigated. It was found that the porosity increases with the particles size while the oxide content rises with decreasing particle size. Caused by lower velocity large particles produce weakly bonded splats resulting in coatings with low elastic modulus, low residual stresses, small oxide content and low hardness. The porosity is high and it is largely comprised of surface connected pores. Small particles produce splats that are bonded through oxide layers. Due to higher particle speed the porosity and the fraction of connected pores are low. The small porosity produces a relatively large value of Young?s modulus andhigh residual stresses. The hardness increases steeply due to low porosity and high oxide content. The coating adhesion exhibits a maximum at intermediate particle sizes.
