The Preparation Technology of the Compound Coating of Cu-Ti-B on Aluminum Alloy Spot Welding Electrode Surface
This study explored the preparation technology of the use of compound materials as aluminum alloy spot welding electrode surface coating,in order to improve the electrode surface temperature strength and reduce electrode wear.The test results show that compound electrode coating of Cu-Ti-B is synthesized in situ at the Zr-Cr-Cu electrode surface by the resistance heat and pressure while spot welding.Structure and component analysis shows that it contains TiB2 strips and grains with good heat resistance,which can intensify the strength of coating base and reduce the plastic deformation generated in part of the electrode surface by blasting right after the electrification.So it is feasible to prolong the electrode life of aluminum alloy spot welding.
