1.4Ultrasonic polishing:A na-etinye ihe na-arụ ọrụ n'ime nkwusioru abrasive ma tinye ya ọnụ na mpaghara ultrasonic, na abrasive na-agbanye ala ma na-egbuke egbuke n'elu ọrụ ahụ site na ịdabere na oscillation nke ultrasonic ifegharị. Ultrasonic nhazi macroscopic ike dị obere, agaghị eme ka workpiece deformation, ma tooling mmepụta na echichi bụ ihe siri ike. Enwere ike ijikọta nhazi nke ultrasonic na usoro ọgwụ ma ọ bụ electrochemical. Na ndabere nke ngwọta corrosion na electrolysis, ultrasonic vibration na-etinye aka ịkpali ihe ngwọta, nke mere na etisasịwo ngwaahịa n'elu nke workpiece na-kewapụrụ, na corrosion ma ọ bụ electrolyte nso n'elu bụ edo. Ultrasonic cavitation na mmiri mmiri nwekwara ike igbochi usoro corrosion, nke na-eme ka ìhè dị elu.
