Description The present paper describes the role of process conditions in developing phase-pure alpha-Al2O3 coatings using solution precursor plasma spraying. Different precursor combinations were employed and two key parameters, namely plasma power and substrate pre-heat temperature, were varied. Detailed studies of in-flight formed particles and splat characteristics were found to correlate well with the Al2O3 coating characteristics. The Al2O3-forming precursor formulation was also found to be crucial in determining the phase constitution of the deposited coatings.
