Problems solved by technology

In the prior art, the diaphragm of the flexible coupling is usually made of stainless steel. Although the strength of the stainless steel diaphragm is higher than that of the early carbon steel diaphragm, and it is more wear-resistant, the stainless steel diaphragm still has elastic limit, strength, Disadvantages of poor hardness, wear resistance and corrosion resistance
In some occasions with high precision, high speed and special requirements, it still cannot meet the requirements

Abstract

The invention discloses an amorphous composite material and a method for preparing a flexible shaft coupling diaphragm, belonging to the technical field of application of amorphous composite materials. The diaphragm of the flexible coupling is made of Ti-based amorphous composite material or Zr-based amorphous composite material. The diaphragm on the flexible coupling made of amorphous composite materials is smelted in a vacuum electric arc furnace using an amorphous composite material ingot, and the copper mold is sucked to cast a plate-shaped amorphous composite material. Heat treatment before and after rolling, two-dimensional high-temperature rolling and room temperature Rolling pre-deformation, rough and finish machining to the required diaphragm size. The diaphragm of the flexible coupling made of amorphous composite materials has the advantages of high elasticity (elastic limit 1.5%-1.7%), high strength, high toughness, high hardness, excellent corrosion resistance and fatigue resistance, and long service life. .

Description

technical field [0001] The invention relates to an amorphous composite material and a method for preparing a flexible shaft coupling diaphragm, belonging to the technical field of application of the amorphous composite material. Background technique [0002] Due to the unique long-range disordered and short-range ordered atomic arrangement, amorphous alloys have some excellent properties unmatched by crystalline alloys, such as high elastic limit, hardness, strength, excellent wear resistance, corrosion resistance and fatigue resistance. However, due to the lack of deformation mechanisms such as dislocations, twins, and phase transformations in crystalline alloys, the deformation of room temperature amorphous alloys can only rely on the initiation and expansion of local shear bands, and room temperature amorphous alloys exhibit brittle fracture. The emergence of amorphous composite materials promptly solved the problem of room temperature brittle fracture of amorphous alloys...
