Abstract

PURPOSE: To manufacture a screw having wear resistance and corrosion resistance in low cost by executing thermal-spraying of wear resistant and corrosion resistant alloy powder onto surface of screw-shaped base material and HIP pressurizing treatment after further, executing thermal-spraying of glass powder onto the thermal sprayed layer.
CONSTITUTION: The screw base material of Cr-Mo steel, tool steel, etc., is worked to obtain the prescribed shape of screw shaped base material. Successively, on this surface, the thermal- spraying of the wear resistant and corrosion resistant alloy powder of Fe series, Ni series, Co series, etc., is executed at about 1 mm thickness. On the surface of alloy powder thermal- sprayed layer formed with this, the thermal spraying of glass powder of 'Pyrex(R)' glass, etc., is executed and the glass powder thermal sprayed layer is formed at about 1mm thickness. The thermal sprayed material obtd. with this, is used as base material for HIP. The heating treatment is pre-executed to this base material, and the hot isostatic pressing treatment is executed. By this method, the above glass powder thermal sprayed layer is softened to form the glass layer along the base material shape, and executing pressurized-sintering to the above alloy powder thermal sprayed layer without using expensive capsule, the alloy layer is formed. After that, the above glass layer is removed and the alloy layer is worked into the prescribed shape to obtain the screw for plastic forming machine having excellent wear resistance and corrosion resistance.
