• Localized corrosion of stainless steel alloys in wastewater treated with an AOP. Dissolved ozone does not result increased pitting susceptibility. Pitting the studied lean duplex is induced by Fenton reagents. Crevice observed both and The examined when applied as a construction material advanced oxidation processes. Both electrochemical immersion experiments have been carried out subjecting ...

Corrosion of metal is a ubiquitous phenomenon that occurs in various paperwork. Atmospheric or uniform, galvanic, crevice, pitting, and microbial corrosion are maximum familiar styles corrosion. The consequences many varied the outcomes those at safe, dependable green operation gadget structures frequently extra serious than simple loss mass metal. screw ups types need for highly-priced replace...

Modular implants are currently widely used in total hip arthroplasty because they give surgeons versatility during the operation, allow for easier revision surgery, and can be adjusted to better fit the anatomy of the specific patient. However, modular implants, specifically those that have metal-on-metal junctions, are susceptible to crevice and fretting corrosion. This can ultimately cause im...

This report describes a case of mechanically assisted crevice corrosion and secondary adverse local tissue reaction in a patient following a total hip arthroplasty, utilizing a modular neck (bi-modular) femoral component. Radiographic evaluation demonstrated a well-positioned, stable, cementless arthroplasty. Upon further evaluation, the patient had elevated serum cobalt and chromium levels, an...

Taper corrosion of the head-neck junction is a potentially significant and devastating problem facing orthopedic surgeons. We present a case of a 53 year old male who presented for routine follow up for a left, large head, metal on metal total hip arthroplasty five years out. The patient was asymptomatic at the visit. X-rays at the time demonstrated a large amount of medial calcar osteolysis. S...

Stainless steel 316L has widely used as bioimplants in cranial plates, dental implants, bone fracture fixation, prothestic joints. However, low wear resistance, in some cases susceptibility to pitting and crevice corrosion in body environment and release of toxic ions from the surface are the basic disadvantages which this material prone to be. It has still applied as a temporary biomaterial du...

A new peridynamic (PD) model for crevice corrosion damage is introduced and cross-validated with experimental results from the literature. Electrochemical mechanisms are reduced to a simple metal-ion concentration-dependent rate. Computations over domains extreme aspect ratios like those seen in crevices efficiently performed by modifying PD formulation accommodate arbitrary-shape horizons. The...
