Many types of springs, titanium springs are just a small part

Titanium spring wire like spring is an elastic element machinery and electronics industries widely used, medical titanium plate spring when under load can have a greater elastic deformation, the kinetic energy into mechanical work or modification energy, and deformation of the spring and reinstated after uninstalling disappear, the deformation energy or kinetic energy is converted to mechanical work. Applicable demanding corrosion, temperature, and other non-magnetic range.

Grade 2 titanium wire We generally said spring is a method for controlling mechanical movement, energy storage build, measuring force size mechanical parts. Many types of springs, titanium springs are just a small part, due to the titanium is light weight, high strength, corrosion resistance and other characteristics, so titanium spring is widely used in chemical, marine engineering, automobile manufacturing and other fields. There are many types of titanium spring: spring tension titanium, titanium pressure bomb, titanium torsion spring. The method of manufacturing titanium springs can be divided into cold roll and hot roll method. Titanium main spring wire material is titanium, titanium wire with a diameter of less than 8mm generally cold roll method, than 8mm hot roll method, heat treatment of titanium springs can be annealing and pickling process according to customer requirements.

Titanium wire carburizing surface treatment

Xinnuo titanium wires form stable carbides with carbon a higher hardness. Growth carbide layer between titanium and carbon diffusion rate of titanium carbide layer to decide.
The solubility of carbon in titanium is small, at 850X: When the total is 0.3% at 600C and at approximately 0.1% B drops due to the small solubility of carbon in titanium, so that substantially only by titanium carbide layer and the lower fork domain deposited layer to achieve the purpose of surface hardening. Removal of the oxygen must be carried out under conditions of carburizing, the surface layer hardness as carburizing for steel powder used against carbon monoxide or oxygen to form carbon monoxide surface reaches 2700MPa and 8500MPa, and the head. It is easy to peel off. Medical titanium plate 

Titanium plate suppliers In contrast to this, in the deoxidation or decarburization conditions, in a thin layer of charcoal may be titanium carbide layer is formed when carburizing. This layer hardness 32OUOMPa, conforming to the hardness of titanium carbide. Carburized layer is substantially greater than the depth of the nitrided layer under the same conditions when the nitriding depth with nitrogen. In the oxygen-rich conditions must take into account the effects of oxygen absorption hardening depth. Only under conditions of very thin thickness, in a vacuum or argon - methane atmosphere before the toner may penetrate a sufficient adhesion strength comparison, using a gas carburizing agent may form hard and particularly good adhesion titanium carbide hardened layer. While the 950T: and 10201: temperature between the conditions for the formation of hardened exhibition in 50fim between and. With the increase of the thickness of the titanium carbide layer becomes more brittle and tend to flake t To avoid decomposition leaving Rui alkyl carbon inclusions invasion of titanium carbide layer, it should be used about 2% volume fraction Rui alkyl provisions dose additive gas carburizing in an inert gas. When using propane additive use methane is formed when carburizing low surface hardness. When the adhesive force reaches Wu Mao OkPa conditions when using propane gas carburizing, although the measured thickness of the hardened layer is very thin, but with the best wear resistance. Absorption of hydrogen in the gas type carburizer conditions using either, but had to remove it in the vacuum annealing.

Titanium welding wire Notes

1, construction workers and welders should wear clean white fine gauze gloves (non-wearing cotton gloves).
2, the processing of non-pads touch and contact with iron materials.
3, welding work as possible in the room, the ambient wind speed should ≤0.5m / s, avoid the draft affected.
4, titanium welding wire should be as short arc welding using welding, using a small welding heat input welding nozzle and retaining 70 ~ 80-degree angle.
5, taking over the tack welding, the butt gap is generally about 0.5mm.
6, each weld seam should be as a complete, must be connected to the welding of the weld, before welding should be clean interface, welding meat lap length of 10 ~ 15mm.
7, titanium spring wire welding, torch should not side to side, can not be removed from the molten end of the wire gas shielded area .
8, the welding arc should be aspirated in advance, can not lift immediately when the torch arc, gas should be postponed until the temperature dropped to below 250 ℃.
9, medical titanium plate gas drag cover the distance of the torch should be the shortest better, and We seek to minimize the contact gap wall. When the tube butt welding, forming side welding in order to achieve the requirements, the welding carried out twice: once for the back cover welding (welding back when you can not fill material) and the other for the forming welding. When the multi-layer welding, must wait before a weld to cool completely, then welded to the next bead.
