Examples are given of the effects of wear and friction, fatigue and creep, and corrosion on the materials used in joint replacement. Cases are quoted where wear from metal-on-metal hip bearings has led to risks
The purpose of this experiment was the bioassay of some materials considered as possible candidates for use in total joint prostheses as load‐bearing members or as wear‐resistant surfaces. Some materials already in use were also tested. 316L stainless steel was used as a control. The materials...
“cannibalized,” and the remainder is either landfilled or recycled. In addition to this, circular systems can have outputs to other systems where resources continue to be used. Think of using wastes as inputs, or cascading components and products for alternate use. As such, many different ...
designing the fibre architecture to be incorporated into a textile layer could drastically lower the apparent Young’s modulus of the textile in comparison to that of the single fibre constituent. The Young’s modulus of the material could also be used to indicate the likely weavability and dry...
the engineer must be familiar with the various test procedures that were used to collect this data. One restriction that must be understood is that mechanical properties are usually determined by a testing a specimen in a laboratory. Caution must be taken as the conditions of the test in the ...
Surface-grafting polymer brushes (SPB), which are used in a versatile technique to easily realize surface modifications, can be commonly used to change the inherent surface physical/chemical properties of materials. In particular, producing functional po
Through its architecture, the experimentation, appreciation, and use of certain materials, construction techniques, local crafts, and site-specific tools aim to preserve stories and pass on the discoveries and learnings that have shaped many of the practices still used in construction today. In ...
This replacement hip joint and socket were 3D printed from titanium Titanium is generally bio-compatible, and has a very high melting point. Although more expensive than other metals in commercial form, it’s a material used in machining that’s actually very abundant in the Earth’s crust but...
The hot melt adhesive is squeezed into the joint by the shrink power to form a perfectly sealed surface, after being heated. HSSC-1 is compatible with standard pipe coating, also can be used for coating bare, replacement pipe section and large radius bends. The system is de...
According to the American Society for Testing Material (ASTM), AM is “a powder bed fusion process used to produce objects from powdered materials using one or more lasers to selectively fuse or melt the particles at the surface, layer by layer, in an enclosed chamber.” ...
