Description

Processing device for Ag-containing titanium-based high-entropy alloy antibacterial material Technical Field The utility model relates to the technical field of material preparation, in particular to a processing device of an Ag-containing titanium-based high-entropy alloy antibacterial material. Background With the increasing population aging, the number of osteoarthritis patients increases year by year, and the need for artificial joint replacement surgery continues to increase. The traditional titanium alloy and cobalt-chromium-molybdenum alloy prosthesis has two core problems of too high elastic modulus and lack of self antibacterial property, and seriously affects the operation effect and the prognosis of patients. In recent years, ag-containing titanium-based high-entropy alloys (Ti-Zr-Nb-Cu-Ag HEAs) have been an ideal material for solving the above problems due to their low elastic modulus, high strength, corrosion resistance and excellent antibacterial properties. In the field of antibacterial joint prostheses, the Ag-containing titanium-based high-entropy alloy remarkably inhibits the formation of bacterial biomembrane through the synergistic effect of the antibacterial activity of silver (Ag) and copper (Cu), and meanwhile, the elastic modulus of the alloy is close to that of human bones, so that the stress shielding effect is effectively reduced. When preparing the Ag-containing titanium-based high-entropy alloy material, the raw materials of titanium, zirconium, niobium, copper, silver and other simple substances are mixed in proportion. The Chinese patent publication No. CN218393363U discloses a mixing device, through the cooperation between the slide bars, movable sleeves, stirring rods, vertical plates and the mixing box that set up, can drive two slide bars through control motor and rotate in the mixing box inside, a plurality of stirring rods on the movable sleeve drive the material and mix the stirring simultaneously, then rotate the mixing box and make the case lid face down, the material of mixing box inside falls on the case lid under the action of gravity this moment, simultaneously the movable sleeve on two slide bars also slides to diaphragm department under the action of gravity, through changing mixing box open-ended direction, make its inside two slide bars reach corotation or reversal purpose, thereby reach better stirring effect, simultaneously when the opening of mixing box down, be convenient for discharge the inside material. Because the high-entropy alloy consists of a plurality of metal elements with equal atomic ratio or near-equal atomic ratio, all elements are required to be uniformly distributed on a microscopic scale to form a stable single-phase solid solution structure, the mixing equipment adopts a mixing mode of a traditional stirring roller, mainly relies on shearing force, convection and diffusion effects generated by mechanical stirring, mixes different particles on a macroscopic scale, cannot apply enough energy to the particles to overcome interaction force among the particles, and therefore is easy to cause uneven distribution of local elements and influence the formation of a stable structure of the high-entropy alloy prepared later.
