Infrared thermography for monitoring heat generation in a linear friction welding process of Ti6Al4V alloy
2017
Abstract The increasing use of titanium alloys in a wider range of applications requires the development of new techniques and processes capable to decrease production costs and manufacturing times. In this regard welding and other joining techniques play an important role. Today, solid state friction joining processes, such as friction stir welding, friction spot welding, inertia friction welding, continuous-drive friction welding and linear friction welding (LFW), represent promising methods for part manufacturing. They allow for joining at temperature essentially below the melting point of the base materials being joined, without the addition of filler metal. However, the knowledge of te…
The Role of Oxidative Stress in the Response of Endothelial Cells to Metals
2012
The involvement of endothelial cells in inflammation and blood vessel formation (angiogenesis) makes them important for the integration of metal implants. Metal degradation products can, however, influence these processes, possibly leading to ineffective wound healing, prolonged inflammation and eventually aseptic loosening of the implant. Different metal degradation processes have been shown to lead to ROS formation. Oxidative stress, therefore, can mediate the reactions of the human body to the implant. While the response of endothelial cells to oxidative stress has been well studied, the effects of ROS produced as the result of metal degradation have not been addressed as yet. Therefore,…
