This work aims at investigating experimentally fretting corrosion, that is, corrosion induced by friction of AISI 316L SS against poly(methyl methacrylate) under small displacements, and subsequently using the data to model wear. The observed wear on the stainless steel has been modeled using the Point Defect Model (PDM). The originality of this approach in applying the PDM to fretting corrosio...

A method for measuring the real-time corrosion rates for Alloy 718, stainless steels (SS) 304L and 316L nuclear grade (NG), aluminum alloys 5052 (Al5052) and 6061 (Al6061), copper (Cu), tantalum (Ta), and tungsten (W) in two separate water systems that were irradiated by 800 MeV protons is presented. The ®rst water system was fabricated entirely of 304 SS, thoroughly cleaned before operation, a...

Introduction: The tibia is most commonly fractured long bone in the body, as it has poor soft tissue coverage, medial surface is completely subcutaneous. The optimum method for skeletal stabilization of open fractures of the tibial shaft remains controversial. In recent years, unreamed intramedullary nailing has become an increasing attractive treatment method for tibial fractures. Due to high ...

The enormous demands for metal implant have given rise to a search for cheap material with good bio-tolerability and resistance to corrosion. Although stainless steel has these properties and is widely used for this purpose, its long term application is still a concern. The corrosion resistance of stainless steel depends on the passive layer. Herein, chemical surface treatment, including passiv...

As the world’s populations increase and age, there is a parallel increase in the number of medical procedures addressed to bone related injuries. It is estimated that approximately 1 million of orthopaedic implant surgeries in association with total joint replacements are needed every year. This number is expected to double between 1999 and 2025 as a result of increasing numbers of musculoskele...

A new miniature high-pressure diamond anvil cell was designed and constructed using 3D micro laser sintering technology. This is the first application of the use of rapid prototyping technology to construct high-pressure apparatus. The cell is specifically designed for use as an X-ray diffraction cell that can be used with commercially available diffractometers and open-flow cryogenic equipment...
