abstract = {Abradable coatings in compressor and high-pressure stages
of gas turbines must provide specific hardness and porosity
values to achieve an optimal cut-in of the blade tips. A
fractional factorial experimental plan was designed to
investigate the influence of the plasma spraying parameters
argon flow rate, current, spraying distance and powder feed
rate on these properties of magnesia spinel. Based on the
results, magnesia spinel coatings with low (~400 HV0.5),
medium (~600 HV0.5) and high hardness (~800 HV0.5) could be
reliably manufactured. Further incursion rig tests confirmed
the dependence of the rub-in behavior and abradability on
the coating characteristics and process parameters,
respectively. Process monitoring was also applied during
plasma spraying of magnesia spinel abradables on batches of
turbine components. The recorded particle characteristics
and coating properties showed a good reproducibility of the
spraying process},
