Toimprove the friction and wear properties of enamel coatings on low carbon steel by the addition of quartz and feldspar in equal proportion. The enamel coating with quartz and feldspar was prepared on Q235 low carbon steel by one-dip enameling. Scanning electron microscope and HSR-2M high speed reciprocating friction tester were utilized to study the microstructure, friction and wear properties of enamel coatings with different quartz and feldspar additions. The enamel coating without quartz and feldspar was characterized by higher hardness and lower roughness, for the large pores inside the enamel coatings had low resistance to crack nucleation and expansion, and caused brittle fracture at the pore edge during friction. With the increase of quartz and feldspar, the melting point and the viscosity of sintering system were reduced, but pores nucleation sites were increased, and the enamel melt diffusion and gas expulsion were promoted, and the toughness and plasticity of the enamel coatings were improved. By the way, the wear debris filled the small pores and the transfer film was formed, thus the fracture tendency of the enamel coatings would be significantly reduced, and mild abrasive wear and adhesive wear were main. However, when the addition of feldspar was over 6%, the network breaking effect of Na2O was obvious in the enamel coating resulting in more Si─O bond fracture and reducing the resistance of small pores to crack propagation, so the wear resistance of the coating became worse. To sum up, the equal proportion addition of quartz and feldspar in the enamel coatings will reduce its the porosity, and improve the toughness and the wear resistance contrarily.
