电弧喷涂具有生产效率高,成本低,工件受热小等优点,在高效防腐、维修、设备制造和特殊功能涂层的制备方面应用广泛,在热喷涂中占有重要的地位。但是,与等离子喷涂和超音速火焰喷涂相比,普通电弧喷涂的涂层质量较低,结合强度约20MPa,孔隙率3％～10％,限制了电弧喷涂的应用。 Arc spraying has the advantages of high production efficiency, low cost and small heating of the workpiece. It is widely used in the preparation of efficient anticorrosive, maintenance, equipment manufacturing and special functional coatings and plays an important role in thermal spraying. However, compared with plasma spraying and supersonic flame spraying, the coating quality of ordinary arc spraying is lower, the bonding strength is about 20MPa and the porosity is 3% ~ 10%, which limits the application of arc spraying.
