Rivet sleeve for titanium self-plugging rivet and preparation method of rivet sleeve

The invention discloses a rivet sleeve for titanium self-plugging rivet and a preparation method of the rivet sleeve, and solves the problems that titanium self-plugging rivets for aerospace in China rely on imports for a long time, are high in cost and are controlled by others, and breaks through the monopoly of an individual manufacturer. The titanium self-plugging rivet for aerospace is composed of a plastic deformation part and a bearing part and is made from high-strength titanium alloy, and the plastic deformation part is made from industrial pure titanium of which an alloy designation is TA1-TA4 or the alloy designation is TA5-TA10. The preparation method comprises the following steps: firstly, designing the position and length of the plastic deformation part of the rivet and the bearing part as required; secondly, calculating and weighing material powder; thirdly, paving horizontally; and fourthly, hot pressed sintering in vacuum. The preparation method provided by the invention is used for manufactur
