As a high-strength material part, titanium alloy parts have high application value in many fields, such as aviation, automobile, medicine, sporting goods and electrolytic industry. In this issue, mastars talks about titanium alloy technology.Mastars as a metal prototype maker, provides rapid sheet metal prototyping,rapid CNC service.rapid prototyping.


Characteristics of titanium alloy parts

1. Not easy to deform

Titanium alloy material has high strength and thermal strength and low density. Compared with steel material, it is only 60% of steel density, which is that titanium alloy material will not have deformation problem even at high temperature of 300 ℃ ~ 500 ℃;

2. Low temperature resistance
Titanium alloy has high low temperature resistance, that is, it can still maintain its mechanical properties at low or ultra-low temperature. It is a material with strong low temperature resistance;

3. Corrosion resistance

Titanium alloy parts can be widely used in the field of aircraft, a very important reason is that they have super corrosion resistance; When the aircraft is flying at high altitude, the substances in the air will have a certain corrosive effect on the aircraft surface. Titanium alloy parts can be effectively treated to ensure the flight safety of the aircraft.

4. Chemical properties

Titanium alloy can react with a variety of metal elements. With the help of chemical reaction, Taihe mechanical properties can be improved to the greatest extent;

5. Low thermal conductivity

The application of titanium alloy parts in aircraft can effectively reduce the failure probability of aircraft parts and avoid the high heat conduction of aircraft parts affecting the normal application of other parts;

6. Small elastic modulus

In the process of using titanium alloy parts, it is forbidden to process them into slender parts, because the elastic modulus of titanium alloy is relatively small and easy to deform; In addition, in the processing process, due to the large rebound of titanium alloy, it is easy to wear the tool.

Cutting technology of titanium alloy

1. Selection of tool materials

The rational selection of tool materials is the primary problem to deal with titanium alloy machining. Titanium containing tools can be used to cut titanium alloy at high speed; Under certain conditions, a stable bonding Cen of titanium alloy is formed on the tool surface, which can inhibit wear;

2. Cutting parameters

Cutting speed has the greatest impact on tool life. The higher the cutting speed, the higher the cutting edge temperature. Therefore, low-speed cutting should be selected; At the same time, the cutting depth has little effect on the tool life, so a larger cutting depth is adopted when the stiffness of parts and machine tools allows.
