Application advantages of flame wire vs arc wire

[velocity]

Flame wire spray is older tech and has some weaker spots.
But i want to discuss about applications. For exp. some people say for Mo spray, flame wire has advantages. Maybe not true %100 but if we want to compare, in which applications flame wire has advantage?

Hi Velocity,

Yes for moly spraying with FS you can adjust the oxygen content, to yield higher or lower hardness. That is one application.

For the anti corrosion market (Al and Zn) spraying with large diameter wires, can give high spray rates: and very high deposition efficiency. Plus the equipment is inexpensive.

However in a job shop, for most applications, you will find arc spray is best, as it has lower heat input, and easier in general to setup and manage the spraying
