Microbiologically influenced corrosion (MIC) of AlZnIn‐Sn sacrificial anodes in marine sediment was investigated by exposing samples to sulphate reducing bacteria (SRB). Samples exposed to the sterile marine sediment were used as control. The results show that pitting corrosion occurs in both the sterile marine sediment and the SRB‐containing marine sediment. However, the corrosion can be increased...
A reliable low-cost method is developed to batch fabricate Micro-Electro-Mechanical Systems (MEMS) resonators with high yield. The key breakthrough in the fabrication process is one novel approach realized to effectively restrain electrochemical corrosion of polycrystalline silicon (polysilicon) electrically coupled with noble metals of MEMS devices by hydrofluoric acid (HF)-based solutions. In addition,...
A simple method is described to protect polycrystalline silicon (polysilicon) from electrochemical corrosion which often happens when the Micro-Electro-Mechanical systems (MEMS) device is released in HF-based solutions, especially when the device contains noble metal. We propose to employ a photoresist (PR) layer to cover the noble metal layer, which electrically contacts with the underlying polysilicon...
Dicalcium phosphate dihydrate (DCPD) coating was deposited on the substrate surface of magnesium alloy with solution treatment. The microstructures and corrosion behaviors of the DCPD-coated samples before and after immersion in simulated body fluid (SBF) for different times were investigated. It is important to note that DCPD was not only transformed into hydroxyapatite (HA) but also induced HA precipitation...
The combination of high electric fields and moisture from the environment can lead to electrochemical reactions causing corrosion, which can severely impact microelectromechanical systems (MEMS) device reliability and lifetime. In this paper, we present a detailed study of the corrosion behavior and surface passivation methods for enhancing the corrosion resistance of surface micromachined polycrystalline...
