      abstract     = {Nanoscale oxide dispersions have long been used to increase
                      the oxidation and wear resistance of alloys used as bond
                      coatings in thermal barrier coatings. Their manufacturing
                      via mechanical alloying is often accompanied by difficulties
                      regarding their particle size, homogeneous distribution of
                      the oxide dispersions inside the powder, involving
                      considerable costs, due to cold welding of the powder during
                      milling. A significant improvement in this process can be
                      achieved by the use of process control agent (PCA) to
                      achieve the critical balance between cold welding and
                      fracturing, thereby enhancing the process efficiency. In
                      this investigation, the influence of the organic additive
                      stearic acid on the manufacturing process of Al2O3-doped
                      CoNiCrAlY powder was investigated. Powders were fabricated
                      via mechanical alloying at different milling times and PCA
                      concentrations. The results showed a decrease in particle
                      size, without hindering the homogeneous incorporation of the
                      oxide dispersions. Two powders manufactured with 0.5 and 1.0
                      $wt.\%$ PCA were deposited by high velocity oxygen fuel
                      (HVOF) spraying. Results showed that a higher content of
                      elongated particles in the powder with the higher PCA
                      content led to increased surface roughness, porosity and
                      decreased coating thickness, with areas without embedded
                      oxide particles.},
