Titanium and titanium alloys have good welding, hot and cold pressure processing, and machining properties, and can be processed into various titanium profiles, titanium rods, titanium plates, and titanium pipes for supply. Titanium is an ideal structural material. The density of titanium is only 4.5g/m3, which is 43% lighter than steel, but its strength is twice that of iron and almost five times that of pure aluminum. It has a low density and high strength properties. This combination of high strength and low density makes titanium rods occupy an extremely important position in technology. At the same time, the corrosion resistance of titanium alloy rods is close to or exceeds that of stainless steel, so it has been widely used in the petroleum, chemical industry, pesticides, dyes, papermaking, light industry, aviation, space development, marine engineering, etc. Titanium alloys have high specific strength (ratio of strength to density). Titanium Flat Washer DIN 125 alloy rods and pure titanium rods have played an irreplaceable role in aviation, military industry, shipbuilding, chemical industry, metallurgy, machinery, medical treatment, and other fields. For example, the alloy composed of titanium and aluminum, chromium, vanadium, molybdenum, manganese, and other elements, after heat treatment, the strength limit can reach 1176.8-1471MPa, and the specific strength can reach 27-33, and the alloy steel with the same strength has only 15.5 -19. Titanium alloys are not only high in strength but also resistant to corrosion, so they are widely used in shipbuilding, chemical machinery, and medical equipment. Among them, corrosion-resistant titanium alloys are mainly used in reactors, towers, autoclaves, heat exchangers, pumps, valves, centrifuges, pipes, fittings, electrolyzers, etc. in various highly corrosive environments. However, due to the high price of titanium alloys, their application is limited.

Why is titanium alloy difficult to process
The machinability of titanium alloy is 20-40% of that of 45# steel, and if the hardness is less than HB300, strong knife sticking will occur; if HB>370, it is too hard to process, so it is best to process titanium alloys with a hardness of HB300-370. The main reasons affecting its machinability are briefly described as follows: 1) Gas impurities (oxygen, nitrogen and hydrogen, etc.) have a great influence on the machinability of titanium alloys, because titanium has high chemical activity and is easy to combine with gas impurities . When the temperature exceeds 600 degrees, titanium welding filler wire is oxidized to form an embrittlement layer, the so-called "tissue alpha layer"; hydrogen embrittlement occurs with hydrogen; hard and brittle TiN is formed with nitrogen at high temperature. 2) The plasticity of titanium alloy is small, which obviously affects its plastic deformation during cutting. The deformation coefficient of titanium alloy is only 1 or even less than 1, while that of ordinary carbon steel is about 3. When cutting, there is a very small contact surface between the chip and the rake face, so that the pressure and local temperature in the contact area are high, and the tool wears quickly. 3) Severe work hardening will occur when titanium alloy is processed. 4) When C>0.2%, the Grade 3 Pure Titanium Tube alloy will form hard carbides, which will cause abrasive wear of the tool and reduce the machinability

Types of pure titanium plates and their differences from other titanium alloys
Pure titanium plates can be divided into three types: hot rolling, forging and cold drawing. The specification of hot-rolled pure titanium plate is 5.5-250mm. Among them: 5.5-25 mm small pure titanium plates are mostly supplied in straight strips, often used as titanium alloys, bolts and various mechanical parts; pure titanium plates larger than 25 mm are mainly used for manufacturing mechanical parts or making seamless titanium Tube blank.
The physical and mechanical properties are different. Due to the difference in chemical composition and strength of titanium alloys, there are differences in physical and mechanical properties. The cold bending performance of the pure titanium plate is better, it can be used as a 180-degree hook, and the threaded titanium can only be used as a 90-degree straight hook; the weldability of the pure titanium plate is better, and ordinary carbon electrodes can be used. Use low-alloy electrodes; threaded titanium is better than pure titanium plates in terms of toughness and fatigue resistance.
The difference between Grade 7 Titanium Sheet and other titanium alloys: 1. The appearance is different. The appearance of pure titanium plate is smooth and round, without lines and ribs. The bonding force of titanium alloy is small, while the bonding force of other titanium alloys and concrete is large. 2. The composition is different. Pure titanium plate (first-grade titanium) belongs to ordinary low-carbon titanium, and other titanium alloys are mostly alloy titanium. 3 The strength is different, the strength of pure titanium plate is low, and the strength of other titanium is high. The plasticity of the titanium alloy is stronger than that of other titanium alloys, that is, the pure titanium plate has a large deformation before being broken, while the deformation of other titanium alloys is much smaller before being broken. 4. The physical and mechanical properties are different. Due to the difference in chemical composition and strength of titanium alloys, there are differences in physical and mechanical properties. The cold bending performance of the pure titanium plate is better, it can be used as a 180-degree hook, and the threaded titanium can only be used as a 90-degree straight hook; the weldability of the pure titanium plate is better, and ordinary carbon electrodes can be used.

Performance requirements of coating targets for hard coating
The performance requirements of the coating target for hard coating are mainly the requirements for the thermal conductivity, electrical conductivity and thermal expansion coefficient of the sputtering target. The temperature of the target increases due to sputtering, the higher the thermal conductivity, the faster the heat transfer, the better the evaporation effect of the target ions, and the higher the deposition efficiency; the smaller the difference between the thermal expansion coefficient of the target and the substrate, the more Well, to reduce the effects of thermal stress.
To sum up, the technical requirements for coating Zirconium Sputtering Target for hard coatings include target purity, density, composition and structural uniformity, etc.; the performance requirements are mainly for the thermal conductivity, electrical conductivity and thermal expansion coefficient of sputtering targets.
