titanium round bar

Three-dimensional titanium wire carburized surface treatment of three-dimensional titanium wire with carbon to form a kind of high hardness of the stability of the carbide. In the growth of the carbide layer between titanium and titanium round bar carbon by diffusion velocity layer of titanium carbide to decide. Small solubility of carbon in titanium, 850 x: when a total of 0.3%, and about to 0.1% at 600 c B due to the smaller the solubility of carbon in titanium so basically only by titanium carbide layer and the bottom sediments 扠 domain to achieve the goal of surface hardening. Must be conducted under the condition of removing oxygen carburizing, because it is suitable for powder of steel carburizing is commonly used for the carbon monoxide and oxygen of the surface of the carbon monoxide and form the surface layer of hardness of 2700 mpa and 8500 mpa, and mesh. Peeling off easily.

By contrast, under the condition of DNA or decarburization, when in charcoal carburizing may form a thin layer of titanium carbide layer. The hardness of this layer is 32 ouompa, accord with the hardness of titanium carbide. The depth of carburized layer is greater than the roughly in the same condition with nitrogen nitriding depth of nitriding layer. That must be considered under the condition of oxygen enriched oxygen absorption impact hardening depth. Only under the condition of thin layer thickness, in a vacuum or argon - people carbon powder to form methane atmosphere enough adhesion strength by contrast, with gas carburizing agent may be especially hard and good bonding formation of titanium carbide hardening layer. T: in 950 and 10201 at the same time: the temperature under titanium tubing price the conditions of formation of the hardening between exhibition between fim and 50. With the increase of thickness, titanium carbide layer become more brittle, and tend to spalling t in order to avoid because rui alkanes decomposition and carbon inclusion of shooting, titanium carbide layer should be adopted about the rules of the volume fraction of 2% Rachel alkanes dose of additives in inert gas for gas carburizing. When using propane additives and the use of methane gas carburizing of 3d titanium wire forming low surface hardness. When bonding wooley reach bases OkPa conditions when using propane gas carburizing, although measure the thickness of hardening layer is very thin, but it has the best wear resistance performance. Under the condition of using gas type carburizing agent to absorb hydrogen, but in the vacuum annealing and had to be removed it.

Titanium is used as a variety of auto parts, its main advantage lies in:

Low density: not only can reduce the titanium tubing price vehicle weight, the moving parts of high speed, can reduce the movement of inertia;

Than high strength: in all kinds of metal materials, the specific strength of titanium is almost the highest, can be used as load-bearing components;

Elastic modulus small: only 50% of the steel, and the fatigue strength, suitable for spring;

Good heat resistance, can be in 200-650 ° C to work long hours, suitable for high temperature components;

Small thermal expansion coefficient, it is Titanium welding pipe not the pound 50% of steel, aluminium, suitable for parts such as engine valve;

Good corrosion resistance, better than that of aluminum, magnesium, and stainless steel, the atmosphere, rain water, antifreeze pavement moisture resistance and hot waste gas containing hydrogen sulfide corrosion, suitable for the working environment is bad part such as the exhaust;

Good frost resistance: 100 ° C below zero in environment, also won't produce brittleness at low temperature;

Good formability: by stamping, hot forging, powder metallurgy, precision casting method such as the preparation of various shapes of components.

Good decorative: by oxidation treatment, can form colorful variety of decorative materials.
