Anotácia textu normy ASTM B481-24 :
This practice describes preparation processes of titanium and titanium alloys to produce adherent electrodeposits of good quality by electroplating. Not all of the processes that have been reported as successful are described, but rather three basic ones that have had the widest use. The purity of reagents and water that shall be used in each process are given. The three processes consist of (1) cleaning by conventional methods such as vapor degreasing, alkaline cleaning, grinding, or blasting, and (2) activating. The first process involves activation by chemical etching which shall be done in the following order of procedure: pickling, rinsing, etching, rinsing, electroplating, and heat treatment. The second process involves activation by electrochemical etching which shall be done by the same procedure as the first process, without the heat treatment step. The third process involves activation by liquid abrasive blasting which shall be done in the following order of procedure: blasting, electroplating, and heat treatment.
