Introduction to Wear-Resistant Powder Materials for Thermal Spraying
To reduce wear caused by material erosion on equipment components, a wear-resistant coating is applied to the surface of these components, thereby protecting the substrate material of the equipment parts. Coating processes typically include plasma-sprayed oxide ceramic coatings and supersonic flame-sprayed alloy coatings.
