Description	Alternativní metody určování složení a pórovitosti jsou použity na materiály s nízkou abrazní odolností, u nichž je obtížné získat kvalitní metalografický výbrus. Výsledky jednotlivých metod, včetně metalografie, jsou porovnány a jsou diskutovány jejich přednosti a omezení. (cs) Materials properties and performance are governed by their composition and structure. These are commonly characterized using materialography and image analysis. However, in abradable materials, obtaining a reliable and representative sample (polished section) for this widespread technique is complicated by their abradable nature and heterogeneity. Therefore, alternative methods are also considered in this paper. They are namely x-ray diffraction and electron probe microanalysis to determine the composition, and mercury intrusion porosimetry, Archimedean porosimetry and helium pycnometry to determine the porosity. These methods, including materialography, were applied on representative abradable materials produced by plasma spraying; their results are compared and the advantages and drawbacks of each method are discussed.
