This case focuses on the black micro-arc oxidation process for pure titanium watch straps, leveraging specialized micro-arc oxidation experimental equipment to achieve dual upgrades in both appearance and performance. The experiment uses pure titanium watch straps as the treatment object, conducting pre- and post-oxidation comparative tests with strict control over process details. Initially, the straps undergo precision surface pretreatment to remove impurities and oxide layers, laying the foundation for subsequent reactions. The straps are then precisely suspended and fixed in the electrolytic tank using specialized fixtures. After presetting power parameters matched to pure titanium material, the equipment is activated to ensure uniform and stable micro-arc discharge, guaranteeing consistent oxide layer formation. Upon completion, the finished straps are rinsed with deionized water and dried, resulting in a uniformly fine black surface with exceptional visual texture. This process not only achieves ideal decorative effects but also significantly enhances the wear resistance of the straps. Testing confirms it can pass a 48-hour wear resistance test, meeting the requirements for high-end watch straps and demonstrating the high adaptability of micro-arc oxidation equipment in titanium alloy surface treatment.
