    Ceratanium (ceramic titanium) is shown to be quite useful. It is sturdy yet lightweight; and Magnet Man in the comic series, says it is paramagnetic. It is thus used in multiple robots, being the key component in Mega Man's armor, the Metal Blades of Metal Man, Cut Man's Rolling Cutter, and Hard Man's body. Chelonium Discworld

  3. Oxide jacking - Wikipedia

    en.wikipedia.org/wiki/Oxide_jacking

    Oxide jacking has caused concrete spalling on walls of the Herbst Pavilion at Fort Mason Center in San Francisco. The expansive force of rusting, which may be called oxide jacking or rust burst, is a phenomenon that can cause damage to structures made of stone, masonry, concrete or ceramics, and reinforced with metal components.

  4. Photocatalytic concrete - Wikipedia

    en.wikipedia.org/wiki/Photocatalytic_concrete

    The photochemical oxidation with the aid of titanium dioxide is much faster because of the energy absorbed by the coating on the block and also because the reactants are held together on the surface of the block. The reaction using titanium dioxide shows a greater oxidizing power than most other metal-based catalysts.

  5. Concrete degradation - Wikipedia

    Example of flat piece of concrete having dislodged with corroded rebar underneath, Welland River bridge across Queen Elizabeth Way in Niagara Falls, Ontario. The expansion of the corrosion products (iron oxides) of carbon steel reinforcement structures may induce internal mechanical stress (tensile stress) that cause the formation of cracks and disrupt the concrete structure.

  6. Corrosion engineering - Wikipedia

    en.wikipedia.org/wiki/Corrosion_engineering

    Corrosion engineering is an engineering specialty that applies scientific, technical, engineering skills, and knowledge of natural laws and physical resources to design and implement materials, structures, devices, systems, and procedures to manage corrosion. [1]

  7. Titanium compounds - Wikipedia

    en.wikipedia.org/wiki/Titanium_compounds

    The +4 oxidation state dominates titanium chemistry, [1] but compounds in the +3 oxidation state are also numerous. [2] Commonly, titanium adopts an octahedral coordination geometry in its complexes, [3] [4] but tetrahedral TiCl 4 is a notable exception. Because of its high oxidation state, titanium(IV) compounds exhibit a high degree of ...

  8. Embrittlement - Wikipedia

    en.wikipedia.org/wiki/Embrittlement

    Cracks must first nucleate. Most embrittlement mechanisms can cause fracture transgranularly or intergranularly. For metal embrittlement, only certain combinations of metals, stresses, and temperatures are susceptible. This is contrasted to stress-corrosion cracking where virtually any metal can be susceptible given the correct environment.

  9. Fretting - Wikipedia

    en.wikipedia.org/wiki/Fretting

    This breaking causes wear debris to be formed. If the debris and/or surface subsequently undergo chemical reaction, i.e., mainly oxidation, the mechanism is termed fretting corrosion. Fretting degrades the surface, leading to increased surface roughness and micropits, which reduces the fatigue strength of the components.
