Abstract

Thermal spraying process for producing protective coatings on fire tubes uses a self-flowing alloy powder with large particles which is fused after spraying on to the tubes. An independent claim is included for use of self-flowing alloy powders with large particles in thermal spraying to produce protective coatings on fire tubes.
