... uniaxial creep testing uniaxial tensile testing THE TERM “THIN FILMS” is usually applied to metallic and nonmetallic layers of thickness of the order of microns or fractions of microns that are deposited on a variety of substrates. Their mechanical resistance is of particular interest, because high...

... electropositive and electronegative metals that chemically bond to form compounds with a specific composition and crystalline structure. Intermetallic films are often formed by depositing the film material on a hot surface so that the adatoms diffuse and react with the surface material, converting it into a...

... at a low angle (5–20°). For metals and semiconductors, the electropolishing route is preferred, whereas for ceramic materials, ion beam milling is usually necessary. Depending on whether the area of interest in the coating is near the substrate interface or further out in the film, thinning of the...

... is, each of these alloys has a high free energy driving oxidation of the metal components and each would corrode at extremely high rates if the oxide film were not present to limit specific steps in the corrosion reaction ( Ref 15 , 16 ). However, the oxide films that form act to limit access of the...

For thermally sprayed aluminum coatings, initial corrosion may produce slight superficial rust staining through pores in the...

... factors that may lead to physical breakdown of the passive film, such as fretting, erosion, or wear. Both particulate debris and metal ions are released into the surrounding tissues as a result of these processes. The use of modular connections in total joint arthroplasty has the potential to lead to...

.... Gold cannot be used as a structural material at elevated temperatures because of creep of the metal. Gold rupture disks usually are not used above 80 °C (175 °F). Pure gold essentially owes its corrosion resistance to the low chemical affinity of the element. Passive film protection, such as occurs...
