Can anyone recommend a suitable material that would stand up to HVOF process while also not allow bridging between the fixture and component?
Many thanks

Hi David
1) if you are looking to making a fixture any ordinary steel like Mild Steel (or) En material also sufficient for all thermal spray processes like HVOF, Plasma etc.
2) To avoid bridging between the fixture and component, you have to design fixture such that there should be small gap between component and fixture by providing chamfer or small step in fixture.
3) Better to use fixture after shot blasting operation.
Finally i want to say that you have to use all your brain in making fixture rather than selecting the raw material for fixture.
