19August, 2020Ceramic balls for orthopedic hip implantsFine ceramics, as the latest generation is known, comprise a family of super materials engineered to achieve extreme performance objectives. Stronger and harder than metals or plastics, they can survive the heat of a blast furnace or the destructive effects of corrosive acids. They can protect people and equipment from electrical charges exceeding a million volts. Designed for high-impact applications, these "super heroes" of the materials sciences can literally stop a speeding bullet. No other family of materials offers the same physical, chemical, thermal, electrical and optical properties as fine ceramics.Today's fine ceramics are at work in applications ranging from smartphones to heart pacemakers ­ and in such extreme operating environments as jet engines, the ocean floor, near-Earth asteroids, and even the surface of Mars. Here are a few examples.AI and IoT: Artificial Intelligence (AI) and the Internet of Things (IoT) hold great potential to advance human productivity, health, safety and living standards in the 21st century ­ with the Wall Street Journal forecasting a net increase by 2030 in global GDP of 16%, or about $13 trillion, through AI alone. Both technologies will require significant advances in data processing power and connectivity, which are expected to create strong demand for microelectronic substrates, semiconductor packages and miniaturized electronic components, including capacitors and crystal Ceramic crystal-device package for advanced electronics Jay Scoviedevices. Some of these newest components are as small as a grain of salt! By facilitating the component miniaturization necessary to allow higher-density circuits, ceramics are expected to play a key role in AI and IoT deployment.Industrial Applications: Because of their historic association with tea cups and dinnerware, ceramics are often assumed to be delicate materials ­ but today's engineered ceramics are a different breed. Many people are surprised to learn that cermet, a ceramic-metal composite, has become essential for advancing the quality and productivity of industrial metal processing ­ in cutting automotive engine parts, drive systems, and aerospace components at high speeds. A CVD coating enhances hardness and wear resistance even further, creating an ideal edge for cutting, turning, milling and finishing in a wide range of steel and cast-iron machining operations.Orthopedic Implants: Inan orthopedic joint replacement, wear resulting from friction at the bearing interface is the No.1 cause of implant failure. The most common failure mechanism involves microscopic particles of "wear debris" that lodge in surrounding tissues and cause osteolysis over time. This issue is gaining prominence as lifestyle factors produce a lower average age among joint replacement candidates, and as patients desire the implant to be a lifelong solution. Orthopedic engineers are consequently focused on reducing or eliminating wear from the joint's bearing interface by combining advanced ceramics with other material technologies. One proprietary material combination has shown to reduce this wear by an astounding 98% in the most recent in-vitro testing.Scientific Instruments: The extreme performance capabilities of fine ceramics make them essential for advancing the frontiers of scientific knowledge. Prominent examples appear in the Mars rovers, asteroid probes, astronomical telescopes, and particle accelerators. Space applications experience particular challenges due to thermal cycling, which can cause phase transformations that degrade key components. To avoid this, satellites and space vehicles with fiber-optic systems have relied on specially formulated ceramic to insure datalink reliability amid the extreme thermal cycling conditions of space. Artificial Intelligence (AI) and the Internet of Things (IoT) hold great potential to advance human productivity, health, safety and living standards in the 21st century
