Shot peening rawatan

Walaupun alkalin degreasing corrosion solution treatment at 70-90 degree can effectively clean the surface of cast aluminium parts, the degreasing corrosion time is difficult to control due the different surface conditions of the parts, including non machined and processed surfaces. If the oil removal corrosion time is too long, uneven corrosion often occurs. Moreover, excessive oil removal and corrosion can also make the surface of the parts rough and without metallic luster, and cannot generate compressive stress to strengthen the surface.

Ini proses uses glass balls for shot peening treatment. The spherical glass shot sprayed onto the surface of cast aluminium parts not only effectively removes oil stains, oxide scales, etc., but also forms many small semi-circular surfaces on the surface of the parts. After light reflection, it presents a metallic luster, and the surface roughness is significantly improved. Moreover, shot peening can also generate compressive stress on the surface, improve the fatigue life of the surface, reduce the sensitiviti of surface to stress corrosion, and greatly strengthen the surface of the parts. The surface treated with chemical oxidation can generate a dense and bright oxide film layer, fully meeting the product design requirements. Therefore, we chose shot peening as the pre-treatment process for kimia pengoksidaan filem pembentukan.

Kaca bola tembakan peening secara amnya kawalan the penyemburan distance to be 200-350mm, the spraying angle to be {60-70 degree , and the spraying pressure to be 5kg/mm2. Pay attention to avoiding long-term spraying of local areas on the surface of the parts.
