The article introduces the preparation process of TC18 titanium alloy forging cake for aviation, and studies the effect of two different double annealing processes on its structure and properties. The results show that: using 820 ℃ × 2h, FC to 750 ℃ × 2h, AC; 580 ℃ × 3h, AC double annealing process, TC18 titanium […]
Detailed explanation of titanium anode: The full name of titanium anode is called titanium-based metal oxide coated titanium anode (MMO). Also called KSA anode. (Dimensional shape-stable anode). It uses titanium as the substrate and brushes the precious metal coating on the titanium substrate to make it have good electrocatalytic activity and conductivity. Titanium anode classification: […]
The process damping effect in milling of titanium alloy is analyzed and verified by experiment. Titanium alloy is a typical hard-to-machine material commonly used in aviation. Its large cutting force per unit area is prone to chatter, deterioration of surface quality, and damage to tools during processing. The chatter of titanium alloy cutting is an […]
1. Analysis of processing difficulties There are a batch of production tasks from an optical machine. This task is a new challenge in terms of processing materials and processing accuracy. Among them, the processing of the convex lens rotation axis has the following problems: The rotating shaft of the convex lens is made of titanium […]
Currently, there are only two industrial methods: HDH method and sodium method. However, the sodium titanium plant has been closed for a long time, so far only the HDH method is still used for industrial production. The centrifugal atomization method and the gas atomization method are mainly used to produce (spherical titanium powder or) spherical […]
Due to the high pressure, the life of the titanium rod is reduced. Therefore, when the titanium die is forged by the closed die forging method, the volume of the original blank must be strictly limited, which complicates the preparation process. Whether to adopt closed die forging should be considered from both interest and process […]
The thermal conductivity of the titanium rod and titanium alloy rod blanks is low, which will cause a great temperature difference between the surface layer and the inner layer during hot extrusion. When the temperature of the extrusion barrel is 400 degrees, the temperature difference can reach 200 ~ 250 degrees. Under the combined influence […]
In the cutting of TC4 titanium plate, the common process flow and content are described as follows: Titanium plate (1) If it is semi-automatic cutting, then the guide rail should be placed on the plane of the titanium plate, and then the cutting machine should be placed on the guide rail, taking care not to […]
Cracks are defects that often occur in the welding of titanium plates. Titanium weld cracks are cold cracks, mainly caused by hydrogen in the weld. The main sources of hydrogen are the moisture and oil stains in the plate and the welding wire. The environmental humidity is the main reason for the increase of hydrogen […]
Vacuum electron beam welding is an advanced high-energy welding technology that was only used in production in the 1950s. It uses convergent high-speed electrons to bombard the joints of workpieces. The kinetic energy of the electrons is converted into heat energy, which causes the bombarded material to heat up and melt. , To achieve the […]
