AI Technical Summary
When the metal parts of the existing test piece holder come into direct contact with the test metal test piece, a galvanic cell will be formed due to the difference in electrode potential, which will accelerate the corrosion of the test piece and make it inconvenient to assemble and install, thus affecting the experimental results.
The design employs a brass bracket and insulating washers. The combination of brass screws, brass nuts, and insulating washers prevents direct contact between the test piece and metal parts. The insertion ring and notch structure avoids electrode potential differences. Combined with the insulation effect of nylon, rubber, or PTFE washers, the test piece is stably suspended and protected against corrosion.
This effectively prevents corrosion of the test piece caused by the formation of a galvanic cell due to the difference in electrode potential, improves the stability and ease of installation of the test piece, and ensures the experimental results.
