The invention provides an abrasion resistant and corrosion resisting method for water pump over-current components. The method comprises the following steps: (1) blank casting, (2) blank surface treatment, (3) glaze slip preparation, (4) enameling, and (5) firing after drying. In the step (3), the mass ratio of the main components of the frit for preparing the glaze slip is that: 40-60 of monox , 0.1-5 of alumina, 1- 10 of boron oxide, 0.1- 5 of potassium oxide, 6-17 of sodium oxide, 0.5-5 of lithium oxide, 1.5-7 of calcium fluoride, 2-6 of sodium fluosilicate, 1-10 of titanium oxide, and 0-2 of others. Relative to the mass of the frit, 5-6% of clay, 0-5% of quartz powder, 0.5-0.8% of boron sand, 0.2-0.3% of sodium nitrate, 2-5% of melanin, and 50-55% of water are added into the frit, and are put into a ball mill to grind to obtain the glaze slip in colloid state. The thickness of the enamel layer attached on the water pump over-current component after firing is between 300 and 700 mu m. The enamel layer is attached on the surface of the water pump over-current component, and has the characteristics of corrosion resistance, abrasion resistance, high pressure resistance, high temperature resistance, and smooth surface with no adhered materials.
