The invention discloses a preparing method of an antibacterial
porous titanium alloy. The method comprises the steps of carrying out ball milling on
raw material powder for standby application; preparing a
silver nitrate solution, adding a dispersion agent, and marking a formed solution as a solution A1; preparing a
reducing agent solution A2; carrying out water bath heating on the solution A1 andthe solution A2 to a
reaction temperature, adding the
raw material powder in the solution A1, then, adding a formed solution into the solution A2, adjusting the pH value, keeping the pH value constant, after the reaction, taking out the reaction solution for scattered cleaning, carrying out cleaning separately with deionized water and absolute ethyl
alcohol for three times, centrifugally precipitating the processed reaction solution, and finally, performing
drying to obtain mixed
powder; adding
ammonium bicarbonate into the mixed powder for uniform mixing, performing pressing forming on the mixture, and carrying out
vacuum sintering, so as to obtain the silver-containing
porous titanium alloy. The problems that in the prior art, a process for preparing the
porous titanium alloy is complex, and pores of the porous
titanium alloy do not have the antibacterial capacity are solved, and the method has the characteristics of being simple in equipment, convenient to operate, high in
controllability and the like.
