A chemical treatment process has been identified as a simple and effective means of improving the bonding of injection-molded polymer to titanium surfaces. This process forms an oxide layer on a titanium surface that includes a layered double hydroxide. The layered double hydroxide both raises the bond strength and minimizes air or water leakage. The process enables the use of titanium alloys with injection molded polymer structural bonds in strong, lightweight, and water-resistant enclosures for consumer electronics.
