The preferred orientation, grain size, and visual appearance of chromium electrodeposited at 30-70°C and under current density of 20-60Amp/dm² of smoothed D. C were studied. The bath composition was as follows:
CrO₃ 250g/l
and H₂SO₄ 2.5
The determination of preferred orientation was conducted by X-ray pole figure method.
The following results were obtained
(1) The brightest deposits obtained at 40 and 50°C were characterized by a high preferred orientation of ‹111›, and they less depended on the current density rather than on the temperature.
(2) A very close correlation was established between the brightness and grain size.
