| Tin is less reactive than the metal it covers, protecting the underlying metal from corrosion. |
| For example, abrasives can damage the protective surfaces of instruments, contribute to corrosion, and impede sterilization. |
| The need for improvement in the weldability and corrosion resistance of these alloys resulted in the second-generation alloys. |
| If both hot and cold water are affected, probably the aerator is congested with rust and corrosion. |
| When we re-installed the outer wings, we reamed the taper hole to clean out the corrosion. |
| The purpose of galvanization is to protect the underlying metal from corrosion. |
