Dos and Do not of using a platinised anode in a hard chrome bath?
DOS Ensure no loose connection to the Electrode terminals Ensure proper Electrode gap and avoid any short circuit Ensure the bath temperature doesnt exceed 70o. Always clean the platinum anode if not operated more than 8 hours Ensure the Rectifier use has a minimum ripple less than 1 % Always maintain the bath condition as stipulated by n the OEM Ensure cleaning only with dilute acid with nylon brush. DONT Dont increase the chromic acid content in the bath above as stipulated by the OEM. Dont operate anode in dry condition without the electrolyte Dont operate the electrode current density above the OEM recommended parameters Dont operate the cell above the recommended voltage, which in most cases would be 20 V. Dont operate the cell for even short periods say few minutes with loose connection, as the Same will detach the platinum plated. Dont operate anode with opposite terminal for long periods Dont use any mechanical means of cleaning such as wire brush and other hand tools. Dont do
