Titanium alloy cylinder lock type folding system hot isostatic pressure forming method

Abstract

The invention provides a titanium alloy cylinder lock type folding system hot isostatic pressure forming method. The method comprises the steps of die preparation, coating sleeve preparation and spherical powder selection, hot isostatic pressure pretreatment, hot isostatic pressure process control, aftertreatment and the like. According to the titanium alloy cylinder lock type folding system hot isostatic pressure forming method, when the hot isostatic pressure technology is adopted for solidifying and forming titanium alloy powder, the characteristics of a titanium alloy part are formed by adopting the way of matching an inner die and an external mold core, accordingly, characteristic forming can be completed, the part forming efficiency is improved, inner surface treatment in the later period is reduced, and the machining period is shortened.

Description

[0003] When forming the relevant parts of the titanium alloy cylindrical lock folding system, if the traditional machining process is used, it is not only time-consuming, but also a serious waste of materials, and the complex structure cannot even be manufactured

Casting can form complex structures and improve material utilization, but the casting process of special materials such as titanium and nickel is very complicated, and the performance of parts is difficult to control; forging can effectively improve the performance of parts, but requires expensive precision molds and large special equipment. high manufacturing cost
