Message from the President: Thermal Spray Characterization Wrap-Up

It was great to see so many of you at the Thermal Spray Characterization: Materials, Coatings and Processes event held in Charleston last month. I’ve received a lot of very positive feedback from the attendees of this event. A big thank you again to Rick Bajan and the organizing committee which made this event possible.

Spray Tips: Coating Structures

The angle of impingement of the spray stream is a source of porosity, because of shadowing. The diagram illustrates the type of shadowing generally associated with coatings sprayed at angles below 45° from the optimal normal angle of incidence.
