Method for quality control of coatings electroplated on deep hole parts based on the principle of Hull cell test// WANG Si-chun*, LI Wen-ming, CEN Ting-ci
Abstract: A fast and effective method for analyzing the problems of bright nickel electroplating on a part with deep hole caused by additives was established based on the principle of Hull cell test. The part to be electroplated was used as cathode in the Hull cell test. The abnormal of additives in the electrolyte was determined by evaluating the appearance change of coating on the part and the conductive copper wire placed in the hole. The application of the method for quality control of coatings in batch production was introduced with some cases.
