Ceramic Ball Bearings are used on high-speed precision machinery

Ceramic ball bearings have been successfully applied in the industrial field.

More applications are silicon nitride ceramic ball bearings. It has the advantages of high limit rotation speed, good precision retention, small starting torque, high rigidity, good dry running performance and long service life, which is very suitable for maintaining high precision and long-time operation under high speed, high temperature, corrosion and radiation conditions. Ceramic Ball Bearing are mainly used in CNC machine tools and high-speed precision machinery, such as high-speed electric spindle bearings, machine tool spindle bearings, dental drill bearings, instrumentation bearings, computer hard drive bearings.

In addition, the hardness of the silicon nitride ceramic is 1 times higher than that of the bearing steel, and the elastic modulus is about 1/3 higher. Under the same load, the elastic deformation of the silicon nitride ceramic is small, so it has good running accuracy.

Additionally,Hybrid ceramic bearings have been successfully applied to the spindle of high-speed machine tools, and have entered the practical stage, such as HPM ultra-precision lathes produced by companies,like Makino who has the spindle speed of 16000r/min.

Brief Introduction of Metallization Ceramics

Brief Introduction of Metallization Ceramics

Advanced ceramics are widely used in electronics and engineering applications for their chemical and mechanical properties. Compared to metals, they are stronger in compression, especially at higher temperatures. Advanced ceramics have a good thermal stability (i.e. a low coefficient of thermal expansion) and good thermal and electrical resistance. They are also hard, and have excellent dimensional stability.

Centorr Vacuum Industries Sells Two High-Temperature Furnaces for Aluminum Nitride Production

Centorr Vacuum Industries announced it has shipped orders for two high-temperature sintering furnaces for 2015 delivery to a leading firm in the production of AlN substrates for the LED market in China.

The designs include CVI’s 2 cu ft graphite furnace for AlN sintering and a refractory metal furnace rated to 1850C for a secondary heating process. These new furnaces build on the success of CVI’s experience in non-oxide ceramics and include modifications made specifically for high-temperature sintering of advanced ceramics.

Centorr’s graphite furnace design includes robust Graphite Tube and Block elements designed for use to 2250°C, with a 4-sided hot zone and integral graphite retort for excellent temperature uniformity. The rigid graphite insulation design provides for long-term service even in the presence of process off-gassing and residual binder contamination, while the new dual-flow Sweepgas® system allows more effective “sweeping” away of the process offgassing. Furnace control is via PLC/Programmable Controllers with Centorr’s custom-designed HMI visualization interface.

Centorr Vacuum Industries Sintervac Non-Oxide design is available in sizes of 2,3,4.5,9,16,24, and 54 cubic foot volumes. The refractory metal furnace design, sized at 1 cu ft will be used for a specific part of the AlN process where a non-graphite hot zone is desired for material cleanliness. The system is rated to 1850C and offers temperature uniformity under +/- 3°C.

Centorr Vacuum Industries is a high temperature vacuum and controlled atmosphere furnace manufacturer with an installed base of over 6500 units worldwide. Their furnace offering ranges from large commercial and production units with hot zones over 3m x 3m, to smaller Lab and Research & Development furnaces for use at temperatures over 3500°C. They are located in Nashua, NH with a fully staffed Aftermarket Field Service group, and Applied Technology Center offering R&D support and toll production service.

Advances in Advanced Ceramics and Coating Processing

This recently published Special Issue of Advanced Engineering Materials, guest-edited by Eugene Medvedovski (Calgary, Canada) and Nahum Travitzky (Erlangen, Germany), is dedicated to novel processing of advanced ceramics, composites, and coatings. This includes both the research and optimization of earlier developed processing routes, which improve the productivity and quality of the materials.

The issue contains 18 invited papers prepared by or with participation of the well-recognized ceramic specialists from academia and industry. The manuscripts cover different aspects of ceramic and coating processing, such as: preparation and use of special ceramic powders and precursors materials, colloidal processing, forming routes of different advanced engineering (ceramics, composites, and coatings) for a variety of applications, materials consolidation, studies of the influence of processing on structure and properties of the materials, and large-scale manufacturing. The results of some selected papers have been presented at international conferences, but some papers describe absolutely new results. Some papers cover the extensive studies conducted by the authors for a number of years and even implementation of the materials and processes with the features of industrial experience. The readers can see that the papers presented in this issue were prepared by the authors from different countries of North America, Europe, Asia, and Australia, and they demonstrate a successful collaboration between the organizations not only from one country, but also from other countries and even continents.

Advanced Ceramics in the Hunt for Comets-[CeramTec]

Piezoceramic multilayer actuators on board the “Rosetta” space probe

On 2 March 2004 at 08:17 CET, an Ariane 5 G+ booster rocket took off from the Kourou space centre in French Guiana. The mission: 67P/Churyumov–Gerasimenko. The payload: ESA’s 3-tonne “Rosetta” cometary probe including science experiments, the “Philae” lander – and8 piezoceramic multilayer actuators with a mass of 31.8 g.

Even at lift-off of the rocket booster 10 years ago, thepiezo actuators built into the “Philae” lander had to withstand the extreme vibrations and thermal shocks before leaving the Earth’s atmosphere. After achieving a near-Earth trajectory around the sun, “Rosetta” carried out several swing-by maneuvers persistently nearing its target: the comet 67P/Churyumov–Gerasimenko.

The probe spent part of the journey in hibernation mode – for 957 days in the freezing coldness of space, 660 million kilometers from the sun, only the on-board computer and some heating elements for the scientific payload were provided with energy.

According to plan, “Rosetta” was activated in January 2014 with the “Philae” lander being activated in March. After the meticulous and successful testing of all on-board instruments for their full operability, the probe will continue to close in on the comet from around two million kilometers to an eventual height of 10km. It is here that on 12 November 2014, a world’s-first should take place: “Philae” will detach from “Rosetta” and land on the comet 67P/Churyumov-Gerasimenko.

Both probe and lander will then explore the comet during its active phase together, providing ESA’s scientists with an insight into the chemical and isotopic composition of the early solar system.

One of the instruments that will be used on the comet’s surface is the MIDAS (Micro-Imaging Dust Analysis System), a high-resolution atomic force microscope that can image the fine structure of individual dust particles and can even make individual atoms “visible”. MIDAS is to investigate the dust on the comet’s surface, analyze the mineral composition and if possible provide information about the age and journey of the comet.


 

The piezoceramic multilayer actuators from CeramTec are responsible for guiding the extremely fine measuring needles in the MIDAS instrument: actuator fine positioning of the highly sensitive needles takes place with a precision of 4 millionths of a millimeter. This means that a surface square with side lengths of a maximum of 100µm (= thousandths of a millimeter) will be scanned with a resolution (accuracy) of 4nm (= millionths of a millimeter). 100µm corresponds roughly to the thickness of a sheet of writing paper – 4nm is 25,000 times less.

Piezo actuators are typically used in precise positioning systems, but that is not their only use. PZT actuators are used for precision guidance in many systems, from laboratory technology and car manufacturing to machine engineering. Even if not quite as spectacular as with “Rosetta” and “Philae” – when precision, speed and power are needed, piezoceramic materials offer interesting and reliable solutions when it comes to micro-positioning, valve control, vibration damping or acoustics.

We will only find out whether the “Rosetta” mission will be a success and if the “Philae” lander can begin its tasks on the 12 November at around 16:00 UTC – this is when the signal confirming the landing should reach the Earth, following a signal propagation delay of 28 minutes and 20 seconds.
