Single cube texture

Cerium oxide (CeO ) was deposited onto a (100) LaAlOj single-crystal substrate with a single cube texture and good in- and out-ofplane alignment. A cp scan of the (220) plane of the CeO film yielded a FWHM of 2.45 ° 0.05 ° the rocking curve of the (200) plane indicated a FWHM of 1.688° 0.006°. A layer of YSZ was then deposited by CCVD on top of this ceria layer. The majority of the YSZ deposited as one cube texture (Figure 3) with only a minor 45° film rotation (<1% intensity) present.

The abrasiveness test results by Mackensen s method for selected cubes of known abrasiveness on Bohme s disc, given in Table 4.5.4, show very clearly a way of detecting inhomogeneities in rock hardness, induced by structural and textural differences. By this method we can observe the influence of pockets, laminae or veins occurring in a rock, which have a different composition from the typical rock structure, and also the influence of cracks and weathering of rock on its overall hardness (abrasiveness). In the tests with cubes (previously used for Bohme tests), some 24 measurements were taken in each case (four on each face) by the Mackensen method. This is sufficient to give a comprehensive characterization of rock hardness, not possible in the same time with any other method (a single...
