| Abstract |
Effects of ultrasonic wave irradiations on the electrodeposition of hard chromium have been determined at frequencies of 28KHz, 50KHz and 100KHz with Sargent baths. Deposited quantities measurements indicate that ultrasonic waves produce a marked decrease in deposited quantities, while the measurements of the hardness and covering powers indicate that ultrasonic waves increase the hardness and covering powers. These effects are correlated with ionic vibration and disruption of concentration gradients by ultrasonic waves and ultrasonic cavitation at the electrode surface. |
