The influence of CVD temperature on the composition, microstructure and morphology of tantalum coating

Firmetal, 2018-03-16 10:47:00 PM

Using the tacl2-h2-hcl reaction system, cold wall chemical vapor deposition (CVD) was used to deposit tantalum coating on molybdenum substrate. The composition, structure and morphology of tantalum coating at different deposition temperatures were studied by X-ray diffractometer, gold microscope and scanning electron microscope. Results show that, within the scope of 1000 ~ 1300 ℃, no change of tantalum sedimentary phase composition, and has a certain effect on preferential growth; The grain size of tantalum deposits increased with the increase of deposition temperature. The surface particles of tantalum sediments are pyramidal and increase with the increase of sedimentation temperature.

3D printing tantalum knee implant

Firmetal, 2018-03-15 09:18:00 PM

Titanium and nickel alloys are commonly used to make medical implants because they have a good strength weight ratio, corrosion resistance, and are relatively abundant in the earth's crust.

Tantalum, by contrast, is a rare metal with many properties that make it a valuable medical grade alloy additive. In addition to extremely high corrosion resistance, tantalum also has chemical inertness. It is a viable alternative to platinum and plays a role in certain sterile environments. By adding materials, this relatively uncommon metal can be used in a small amount and optimizes its potential by using a laser aided additive manufacturing system.

Titanium alloy screw

Firmetal, 2018-03-08 10:15:00 PM

Life everywhere need fasteners, now so important, in the fasteners for cleaning the experience of the titanium alloy screws to talk a summarized below: not good cleaning method, mainly for cold heading adhered on the surface of the processing or machining titanium alloy screws of cooling oil residual oil, oil heat treatment quenching fastener surface residual oil after cleaning.

Titanium alloy screw first method alkaline water cleaning method: the simplest alkaline water cleaning is direct heating or indirect heating cleaning tank, cleaning solution is 3% ~ 10% N2CO3 or NaOH aqueous solution. For carburizing and carbonitriding self-drilling titanium alloy screws, tempering before the middle of the multi-purpose cleaning heating to 50 ~ 70 ℃ 5% ~ 10% sodium carbonate solution. Connected mesh belt furnace belongs to this class. Titanium alloy screw cleaning titanium alloy screw is usually sprayed and immersed in dual mode. If hot water is used for washing, it is better to wash with hot water. Finally, the high-pressure air is used for drying. The main drawback of alkaline water cleaning method is that the cleaning effect is not very good, especially the blind hole of the fastener and the spot and residue of the groove. The waste water produced by alkaline water cleaning must be neutralized, and waste oil can be recovered to meet the environmental requirements.

The properties of tantalum

Firmetal, 2018-03-06 09:30:00 PM

Tantalum is also a kind of rare metal is steel gray luster, melting point 2980 ℃, the density of 16.6 g/cm 3.Tantalum is similar to niobium and is a very stable chemical element. Only fluorine, hydrofluoric acid, acidic solution containing fluoride and sulfur trioxide can react with tantalum. It reacts with a concentrated solution at room temperature and is dissolved in a molten base. The density of tantalum in mild oxidation to the start of the 200 ℃.Tantalum has good low temperature plasticity, tantalum alloy even in - 196 ℃ can keep the ductility. Tantalum also has the ability to absorb hydrogen, nitrogen, etc, and it is in 200-300 ℃ under the suction, high temperature 800-1200 ℃ under the condition of vacuum and precipitation.

Firmetal, 2018-03-05 10:05:00 PM

Carbon nanomaterials are the enemy.
For the past decade, scientists have been trying to find materials that make high-performance supercapacitors. Currently the most popular materials are non-carbon nanotubes and graphene, but scientists are still not satisfied with their conductivity.

In this study, by the Massachusetts institute of technology mechanical engineering professor Ian w. hunter, saeed m. wheat, force and three researchers at the university of British Columbia in Canada team behind the study, after many experiments, finally selected the niobium nanowires. McVakley and his colleagues have demonstrated that high energy density is not unique to carbon nanomaterials, and niobium nanomaterials may be a better choice.
