Material and surface treatment of ultrasonic mould of titanium alloy

Titanium alloy ultrasonic mould material

Titanium alloy with low density, high strength and other characteristics, is now widely used in aerospace, biomedical, notebook computer, digital camera, mobile phone, VCD, DVD, PDP TV and other shell and auto parts of important materials. The titanium alloy used in the ultrasonic mold is only 6AL4V, and Grade5 titanium alloy is the most commonly used titanium alloy. The main components are 6 percent aluminum, 4 percent vanadium and about 90 percent titanium. Hexagonal titanium alloy because of all aspects of the balance of characteristics. And can welding and heat treatment, combined with the characteristics of 482 degrees Celsius below it is very stable, so the titanium alloy on the market, its share of more than 50 percent , that is to say, its application field, from the spacecraft's components, air turbine blades, ships and submarines in the sea of the turbine blades, and even artificial bones and casing, All use it because it is easy to use and relatively easy to obtain.

Surface treatment of ultrasonic mould of titanium alloy

Titanium alloy material must undergo special heat treatment before making the ultrasonic mold to increase its bremsstrahlung and strength; Titanium alloy material itself bremsstrahlung is very high but hardness is not high, so if there will be surface wear problem in actual use, its pressed surface needs to be coated again to increase its pressed surface hardness. At present, tungsten carbide or ceramic magnet are mostly used in Thermal Spray on the pressing surface of titanium alloy horn. The method is to melt tungsten carbide or ceramic at high temperature, and Spray on the horn where the hardness is needed. Ultrasonic titanium alloy horn can not be sprayed completely, otherwise it will affect the resonance of the horn. As it is sprayed locally, the fixture must be made to insulate the mold from spraying. The surface hardness of ultrasonic titanium alloy horn can reach HRC60 degree 67 degree .

Thermal Spray is commonly called Metallizing in the United States. Titanium alloy does not have the problem of corrosion, so the surface treatment can be polished, but also the use of beads to make surface treatment.
