In thisstudy,thethermaldiffusivitiesoffreestandingmulliteandforsteritecoatingsandatwo-layerforsterite/mullitesampleweremeasured,
using thelaser flash method,andcomparedwiththetheoreticalvalues.Toachievethisgoal,thethermalpropertiesofforsterite,mullite,anda
forsterite/mullite multilayercoatingdepositedwithaDC-arcplasma-spraygunwereinvestigated,andthethermaldiffusivityforthecoatings
were calculatedandmeasured.Theapparentthermaldiffusivityvaluesfortheforsterite/mullite-layeredsamplewerecomparedwiththe
theoretical apparentthermaldiffusivityvaluesthatweredeterminedbycalculatingthesumofthedataforeachlayer.Alinkbetweenthecoating
characteristics andtheresultsoftheexperimentsareprovided.
