Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
77 words
AN ELECTROCHEMICAL PROCESS FOR PRODUCING A HARD, ADHERENT COATING ON THE SURFACE OF AN ARTICLE COMPRISING AT LEAST ONE METAL SELECTED FROM THE GROUP CONISTING OF AL, ZN, BI, NI, CO, FE, CU, AG, AU, TI, ZR, V, MO, W, NB, AND TA, SAID PROCESS COMPRISING SUBJECTING SAID METAL TO ANODIC SPARK REACTION IN AN AQUEOUS ELECTROLYTE WHEREIN THE ANION CONSTITUENT CONSISTS OF ALUMINATE ION IN A CONCENTRATION RAGING FROM AN EFFECTIVE NORMALITY UP TO 0.3 N.
