  Polishing knowledge related to titanium alloy screws In the process of diversified and high-end development of industrial products, how to improve the quality of molds that directly affect product quality is an important task. In the manufacturing process of titanium alloy screw molds, the smooth processing and mirror processing after shape processing are called part surface grinding and polishing processing, which are important processes to improve the quality of the mold. Mastering reasonable polishing methods can improve the quality and service life of titanium alloy screw molds, thereby improving product quality. Common polishing methods and working principles 01 Mechanical polishing Mechanical polishing is a polishing method that removes the protruding parts of the workpiece surface by cutting or causing plastic deformation on the material surface to obtain a smooth surface. It generally uses oilstone strips, wool wheels, sandpaper, etc., and is mainly manually operated. For surfaces with high quality requirements, ultra precision polishing can be used. Ultra precision polishing is the use of specially designed grinding tools, which are tightly pressed onto the machined surface of the workpiece in a polishing fluid containing abrasives and perform high-speed rotational motion. By utilizing this technology, Ra0.008 can be achieved μ The surface roughness of m is the best among various polishing methods. This method is often used in optical lens molds. Mechanical polishing is the main method of mold polishing.

• Titanium alloy in the pharmaceutical industry 2023-06-02

  The pharmaceutical industry is an important industry related to people's physical and mental health, including pharmaceuticals, medical machinery, sanitary materials and many other fields, and occupies an important position in the national economy. Titanium is widely used in the pharmaceutical industry due to its non-toxicity, harmlessness and good compatibility with the human body. In pharmaceutical production, pharmaceutical equipment is easily damaged by corrosion due to the fact that the production of drugs is inseparable from acids, alkalis and salts. The use of steel equipment not only can not solve the problem of serious corrosion of equipment, but also cause a lot of human, material and financial losses, affecting normal production. The use of titanium equipment is a good solution to this problem. In the production of several major commonly used drugs, the use of titanium equipment has good corrosion resistance, and has gained considerable economic benefits. 1.Vitamin B1 production Our country mostly use hydrogen chloride conversion method to produce vitamin B1, the finished product using cyclone drying, two cyclone separation.

• Cast titanium alloy properties and applications in the valve industry 2023-05-21

  Compared with previous alloy materials, titanium alloys have many advantages such as low density, high specific strength, corrosion resistance, excellent high and low temperature performance, so they can be more widely used in many fields such as petrochemical, marine environment, biomedicine, aerospace, automotive industry and naval vessels. Cast titanium alloy is titanium alloy obtained by casting into the desired shape, of which the most widely used is ZTC4 (Ti-6Al-4V) alloy, with stable process performance, good strength and fracture toughness (below 350 ℃). As the main control parts of various special environments and special fluid medium pipeline transmission systems, valves have become an important part of many equipment in production, and it can be said that no industry can do without valves. Due to the different environmental, temperature and media requirements in different fields, valve selection is particularly critical and widely valued. Titanium alloy and cast titanium alloy as the main body of the valve due to its corrosion resistance, high temperature and low temperature performance, high strength and other good superior performance in the valve field has a broad prospect. Commonly used cast titanium alloys 1.1 Types With the development of science and technology and production needs, different kinds of cast titanium alloys are developed and used in many fields.

• What are the materials of aircraft engine turbine blades? What are the cooling methods of turbine blades? 2023-02-13

  What are the materials of aircraft engine turbine blades? What are the cooling methods of turbine blades? Turbine blades are an important component of the turbine section in a gas turbine engine. The high-speed rotating blades are responsible for drawing high-temperature and high-pressure air into the burner to maintain the engine's work. Next, let me tell you in detail what are the materials for the turbine blades of the aircraft engine and what are the cooling methods for the turbine blades. 1. What are the materials of aircraft engine turbine blades? A. Deformed high temperature alloy The development of wrought superalloys has a history of more than 50 years. The wrought superalloys commonly used in domestic aircraft engines are mainly Cr-Ni alloy systems and Cr-Ni-Co alloy systems. For details, refer to Table 1. As the content of aluminum, titanium, tungsten, and molybdenum increases in superalloys, the material properties continue to improve, but the hot workability decreases; adding expensive alloying element cobalt can improve the overall properties of the material and improve the stability of the high-temperature structure. B. Cast Superalloys The bearing stability of cast turbine blades increased from about 750°C in the 1940s to about 1700°C in the 1990s. The cast superalloys for blades are shown in Table 2. C. Superplastic forming of titanium alloys At present, the most commonly used titanium alloys for superplastic forming blades are Ti6Al4V and Ti6Al2Sn4Zr2Mo. More titanium alloy materials are shown in Table 3. Although the application of composite materials has a growing trend recently, there are disadvantages that are difficult to solve at this stage, such as: High manufacturing costs , cannot be recycled, and has poor high-temperature performance, so titanium alloys are still the main materials for superplastic form

• Application of titanium alloy in bicycle and auto racing field 2023-01-11

  Application of titanium alloy in bicycle and auto racing field Titanium bicycles have the advantages of light weight, high strength, good corrosion resistance and fatigue resistance. Since the mid-1980s, titanium bicycles have developed rapidly, which has greatly promoted the application of titanium materials. For example, ANCOTECH, HAYNES INTERNATIONAL. and SANDVIK SPECIAl. METALS, three companies producing Ti3Al-2.5V pipes in the United States, have all turned to the bicycle industry. In terms of material selection, Ti-3Al-2.5V and Ti-6Al-4V are the most commonly used titanium alloys for bicycle frames. Compared with other titanium alloys, the biggest advantage of Ti-3Al-2.5V is high yield strength and good process plasticity , and has good welding performance, the disadvantage is the high price. Although it was developed for aircraft hydraulic systems, it meets the material performance requirements of the bicycle market due to its good formability, corrosion resistance and elongation, combined with high fatigue strength and low density. In the past few years, frames made of industrial pure titanium arms and non-aerospace Ti-3Al-2.5V (sports grade) titanium alloys have been popular, and Ti-6AL-4V is the most mature application with relatively good comprehensive mechanical properties. It is the titanium alloy material with the most complete performance data. It has good process plasticity and superplasticity, and is suitable for various pressure processing and forming. It can also be welded and machined in a variety of ways, but the formability, weldability and machining The performance is not as good as the former. In terms of making frame, Ti-6Al-4V is also attractive. It has slightly higher modulus and strength than li-3AL-2.5V, but it is more difficult to process it into small diameter bicycle frame tubing. The crankshaft positioner, pedals, handlebars and other bicycle parts connected to the frame are mostly made of Ti-6Al-
