| Summary: | Background. The object of research is a ferroelectric film of barium titanate, for which the authors proposed
a method of microarc oxidation, previously widely used for the development of the surface of products made of metals
and alloys of the light group. The subject of research is the parameters characterizing the quality of the obtained film,
which also determine the possible directions of its use. In the presented study, the spectral composition and surface roughness
are considered as such parameters. Materials and methods. The method of microarc oxidation was used to obtain a
ferroelectric film of barium titanate. In this case, the titanium substrate was immersed in a galvanic cell filled with an electrolyte
based on barium hydroxide. A Mitaka PF-60 laser contour profiler was used to measure roughness. Results. The
results of measurements of surface roughness and spectral composition of barium titanate on two types of samples are
presented: with a substrate pre-prepared in lactic acid and an untreated titanium substrate. Conclusions. The mainparameters characterizing the roughness are determined: the arithmetic mean deviation of the profile, the height of the
irregularities at ten points, the maximum height of the irregularities and others. The surface roughness of barium titanate
depends on the method of its preparation and processing. A comparative analysis of the presented experimental results
was performed, which confirmed an increase in hardness and a decrease in the roughness of coatings for substrates that
were subjected to preliminary etching. |
