Erosive Wear Resistance of Epoxy Resin/SiC Wear Resistant Coating Modified by Polyurethane

More Information
  • Received Date: September 04, 2009
  • The adhesive strength and erosive wear resistance of SiC particles wear resistant coating bonded by polyurethane modified epoxy resin were studied by changing additive content of toughening agent polyurethane (PU).The results show that proper addition of PU could improve the bond behavior of epoxy resin.When PU addition was 15wt%,the bonding strength of SiC wear resistant coating bonded by modified epoxy resin was the highest.The erosion wear properties would be changed as the impact angle changed.The best erosion wear resistance would be obtained at large impact angle when the PU content was 30wt%-35wt%,and at small impact angle when the PU content was 5wt%-15wt%.The erosion wear property of SiC wear resistant coating bonded by modified epoxy resin was better than the white iron under the same impact condition at both small and large impact angles.
