Study on the Bonding Strength of Arc Spraying Amorphous Coating

摘要

The cored wires were fabricated using five kinds of amorphous compositions with high Fe content. The cored wires were sprayed to form coatings by high velocity arc spraying (HVAS) after optimizing technology. We studied the bonding strength of the coatings. The results are as follows: combining ways between coating and substrate are mainly mechanical combination. The average bond stress is above 30 MPa.
