For goods that must be protected from corrosion or external environmental influences, volatile corrosion inhibitors (VCI) applied in packaging material are a suitable solution. VCI packaging material is easy to use and cost effective. The gas phase forms a protection … Weiterlesen …
New, advanced materials are often driver of technologies, especially for aeronautics applications. Many materials have been developed to resist severe working conditions which usually couple high temperature and mechanical stress corrosion. For these applications, non-oxide ceramics are promising materials, in … Weiterlesen …
The synthesis of several types of one-dimensional structures like nanowires, nanobelts, and nanotubes have recently attracted considerable interest. Because of their one-dimensional structure vertically aligned nanostructural arrays exhibit a much higher active surface than comparable thin film arrays. In particular, … Weiterlesen …
More than ten years ago a technology of forging crank shafts, the so called TR method, was developed at the Metal Forming Institute in Poznań, Poland. This technology provides very good results for cranks with shoulders of a shape close … Weiterlesen …
Carbon fiber-reinforced carbon (C/C) is a composite material consisting of carbon fiber reinforcement in a matrix of graphite. The material is dedicated to very high-performance and high-cost applications, mainly in the domain of aerospace technology. C/C composites are most widely … Weiterlesen …
Titanium and its oxide TiO2 attract great interest as they can improve the bioactivity of traditional orthopedic implantable devices. The thin native oxide TiO2 is thermodynamically and chemically very stable. A high strength:weight ratio, good biocompatibility, and biological inertness make … Weiterlesen …
Cellular metals exhibit excellent specific strength and stiffness. They have multifunctional potential in areas such as aerospace and civil engineering. Honeycomb for example is widely used as a sandwich core material. However, if the internal space is to be used … Weiterlesen …
Titanium is widely used in biomedical fields due to its good biological performance and good mechanical properties. To avoid problems such as infection after insertion of implants a combination of drug and device is a promising approach. The convergence of … Weiterlesen …
