An Integrated Study of Thermal Spray Process-Structure-Property Correlations: A Case Study for Plasma Sprayed Molybdenum Coatings
Popis výsledku v původním jazyce
The particle-jet interaction, particle impact and the particle-substrate interaction during coating deposition was investigated. Commercial grade spherical molybdenum (Mo) powder was plasma sprayed and the spray stream was characterized for resulting particle state. A 'splat map' was deposited capture the fingerprint of the plume cross-section. Subsequently, coatings were deposited at selected spray conditions on an 'in situ' curvature measurement instrument to measure coating residual stresses and to coating modulus. Splats and coatings were characterized by microdiffraction, nano and microindentation for elasto-plastic properties and by electron microscopy. Subsequent splat and coating characterization provides insight into the correlation between processing parameters, resultant particle states and final coating properties. The role of particle temperature and velocity on the splat morphology and residual stress is explained in the results.
