The present work aims to determine the phase composition of multi‐phase yttria‐stabilized zirconia, nickel oxide, nickel (YSZ‐NiO‐Ni) coatings using X‐ray diffraction (XRD) analysis. The ceramic layers were fabricated onto the stainless steel and Al2O3 substrates by vacuum plasma spray technique. The known mass ratio of YSZ, NiO, Ni powder mixtures were prepared carefully for the XRD analysis. An analytical software involving background elimination, the split‐Pearson VII peak approximation, was used for the peak intensity and area calculations. The relative XRD peak areas of the powder mixtures were compared with those of the corresponding coatings. Comparison of peaks and mass balance equation allowed to eliminate the influence of the absorption factor and to estimate the phase composition of YSZ, NiO, and Ni in the coatings. The concentration of phases was calculated with a relative error of less than 5%.

“…applied when there is no suitable internal standard or the QXRPD method must be carried out freely from the interference of the other phases. Esteve et al [9] have reported the determination results of mixtures of eight crystalline phases by the RQA standardless method. The results indicated that their deviations are between 0.2 and 9.6% in which the larger errors related to the larger residuals (R p and R wp ).…”

RESUMOAtualmente, procuram-se sistemas de manejo que preservem ou melhorem as qualidades do solo, tanto mineralógicas como orgânicas, priorizando maior produtividade. Este trabalho teve como objetivo verificar qualitativamente, por meio das técnicas de fluorescência de raios X, difração de raios X e infravermelho com transformada de Fourier, os efeitos provocados pela utilização dos manejos: plantio convencional, preparo mínimo e plantio direto, por 24 anos, na mineralogia de um Latossolo Vermelho distrófico de Ponta Grossa, PR. Não foram observadas mudanças significativas na mineralogia do Latossolo estudado, por meio das técnicas utilizadas, quanto aos diferentes manejos durante os anos de sua aplicação. Pôde-se verificar, qualitativamente, a presença dos minerais gibbsita, caulinita, haloisita, montmorilonita, hematita, rutilo, anatásio, goethita e quartzo.Termos de indexação: plantio convencional, preparo mínimo, plantio direto, mineralogia.(1) Trabalho apresentado no XXXI Congresso Brasileiro de Ciência do Solo, 2007 (Gramado, RS).
