Problems solved by technology

The high elasticity and high hardness of amorphous alloys make traditional mechanical polishing methods have problems such as poor effect and low efficiency; electrochemical polishing is also limited by the high resistivity of amorphous materials, and the electrolytic polishing electrolyte is often a highly corrosive chemical substance. Such as sulfuric acid, hydrofluoric acid, etc., it is difficult to clean after throwing away, and there are chemical residues, which leads to the inability of the treated surgical instruments to achieve the ideal medical performance
[0003] In the existing amorphous alloy polishing method, when the current is passed through the amorphous alloy, the content of free electrons in the large current is large, and the free electrons move in a direction. By colliding with the atoms in the amorphous, the kinetic energy is transferred to the atoms, so that the atoms Increased irregular thermal motion

Abstract

The invention relates to an amorphous alloy polishing method. The method is characterized in that the amorphous alloy is used as an anode and is connected to the positive electrode of a direct-currentstabilized voltage power source and is immersed into a polishing groove containing the polishing solution, and a conductive material is used as a cathode and is connected to the direct-current stabilized voltage power source and is immersed into the polishing groove; and the direct-current stabilized voltage power source is connected to carry out plasma polishing on the amorphous alloy, wherein the temperature of the polishing solution is 50-100 DEG C, the voltage of the direct-current voltage stabilized power source ranges from 100V to 380V, and the current density of the direct-current voltage stabilized power source ranges from 0.2 A / cm<2> to 1 A / cm<2>. According to the method, the amorphous alloy is polished by adopting the direct-current voltage, the current density is small, the impact force on atoms in the amorphous alloy is small, the crystallization phenomenon of the amorphous alloy cannot be caused, the polishing quality is ensured, and the quality of the amorphous alloy isnot influenced.
