Studies were made on the effects of rectified wave form on preferred orientation and internal stress of the chromium electrodeposited from Sargent Bath under current density of 30Amp/dm2 and at 50°C.
The results obtained were summarized as follows:
(1) The high preferred orientation of ‹111› was obtained from smoothed D. C. and a deposit of random orientation was obtained from imperfect D. C.
(2) The grain diameter of the deposit from smoothed D. C. was 317Å and that from imperfect D. C. was 2718Å.
(3) Cracks were produced on the surface of deposit from imperfect D. C.
(4) Tensile stress was found on the surface of deposit from imperfect D. C.; whereas, compressive stress was found on that from smoothed D. C.
