Title
Erosion Behavior of Adhesive / Ceramic Composite Coatings
김형준Hyung Jun Kim, 윤병현Byoung Hyun Yoon, 권영각Young Gak Kweon
Abstract
Composite coatings composed of ceramic powder and adhesive were studied to develop a method for repair or maintenance of facilities under particle erosion conditions. Wear resistant ceramic powders such as Al₂O₄, SiC, and WC were mixed with epoxy or urethane base adhesive. The resulting composite materials were coated on SS41 steel plate and tested to assess a particle erosion properties. Test results indicate that both the shape and size of the ceramic filler influence the erosion rate of the composite coatings. Epoxy based coatings are snowing better erosion resistance than that of the urethane based coatings. Erosion resistance of the epoxy/ceramic composite coatings is superior to that of the commercial metal paste which is used for anti-wear repair. Finally, it is careful to rank the erosion resistance of the adhesive based composite coatings.
