Abstract

The invention relates to the technical field of alloy metal processing, in particular to a titanium alloy pickling and passivating processing technology which comprises the following steps: putting a titanium alloy workpiece into a discharging mechanism, and then sequentially carrying out pickling, passivating and cleaning treatment on the titanium alloy workpiece. The titanium alloy workpiece can rotate in the discharging mechanism and also can rotate, rotation of a rotating rod drives a driving gear to rotate, the driving gear drives a driven gear with the meshed surfaces to rotate, and in the rotating process of two rotating frames, a discharging frame arranged between the two rotating frames synchronously rotates along with the two rotating frames. And therefore, the whole surface of the titanium alloy workpiece in the discharging frame can make full contact with a pickling solution and a passivating agent, the uniformity of pickling and passivating of the surface of the titanium alloy workpiece is guaranteed, and the problem that at present, the titanium alloy is soaked in the pickling solution, bubbles exist, and waste is attached to the surface of the titanium alloy, so that the pickling and passivating effect is affected is solved.

Description

technical field [0001] The invention relates to the technical field of alloy metal processing, in particular to a titanium alloy pickling and passivation processing technology. Background technique [0002] Titanium alloy is widely used in aerospace due to its good corrosion resistance, high working temperature range, high specific strength, casting can directly form structural parts of various shapes and sizes near net size or net size, etc. , chemical industry and other industries; due to the oxide layer or other dirt on the surface of titanium alloy parts during the production process, and the oxide layer on the surface of the part also has a certain impact on the performance reliability of the part, generally the casting needs to be cleaned after the sandblasting process Pickling passivation; pickling can not only remove the oxide layer and other dirt on the surface of titanium and titanium alloy parts, but also remove a small amount of titanium alloy materials according...
