Abstract
A coated article has: a metallic substrate (22); a bondcoat (30); and a thermal barrier coating (TBC) (28). The bondcoat has a first layer (32) and a second layer (34), the first layer having a lower Cr content than the second layer.
Claims23
A coated article comprising:
- a metallic substrate (22);
- a bondcoat (30) comprising:
- a first layer (32);
- and
- a second layer (34), the first layer having a lower Cr content than the second layer;
- and
- a thermal barrier coating (TBC) (28).
4 more elements
A method for cathodic arc deposition from a first cathode (308) and a second cathode (310), the method comprising:
- placing one or more substrates in a chamber (304);
- generating an arc (360) between the first cathode (308) and an anode (302) to deposit a first material from the first cathode;
- generating an arc between the second cathode and the anode to deposit a second material from the second cathode;
- and
- shifting a relative position of a magnet (318) and the first and second cathodes to shift from depositing the first material to depositing the second material.
2 more elements
An apparatus (300) for cathodic arc deposition, the apparatus comprising:
- a chamber (302);
- a first cathode (308);
- a second cathode (310);
- a magnet (318);
- and
- an actuator (322) for shifting a relative position of the magnet and the first and second cathodes shift from depositing from the first cathode to depositing from the second cathode.
