Product description
1.Product Description
Titanium-based platinum anodes are primarily used as anodes in high current density and highly corrosive environments.
2.Preparation Process
-CVD Method: A platinum compound is coated on a titanium substrate and then reduced at high temperature in a vacuum environment to form a dense platinum coating. This coating is suitable for specific electrochemical environments.
-PVD Method: In a vacuum environment, a platinum target is bombarded by plasma, depositing platinum atoms onto a conductive titanium substrate. This method is suitable for atomic deposition and has a thickness of <200nm.
-Water-Soluble Electroplating Method: Platinum ions in a solution are deposited onto a conductive titanium plate using electrochemical forces, forming a strong bond. This method is suitable for platinum coatings >1µm thick.
3.Performance Advantage Comparison
