  2. Vitreous enamel - Wikipedia

    en.wikipedia.org/wiki/Vitreous_enamel

    The powder melts, flows, and then hardens to a smooth, durable vitreous coating. The word vitreous comes from the Latin vitreus, meaning "glassy". Enamel can be used on metal, glass, ceramics, stone, or any material that will withstand the fusing temperature. In technical terms fired enamelware is an integrated layered composite of glass and ...

  3. Electrical discharge machining - Wikipedia

    en.wikipedia.org/wiki/Electrical_discharge_machining

    A separate EDM head specifically for small hole drilling is mounted on a wire-cut machine and allows large hardened plates to have finished parts eroded from them as needed and without pre-drilling. Small hole EDM is used to drill rows of holes into the leading and trailing edges of turbine blades used in jet engines. Gas flow through these ...

  4. Metal casting - Wikipedia

    en.wikipedia.org/wiki/Metal_casting

    A durable plaster intermediate is often used as a stage toward the production of a bronze sculpture or as a pointing guide for the creation of a carved stone. With the completion of a plaster, the work is more durable (if stored indoors) than a clay original which must be kept moist to avoid cracking.

  5. Hardening (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Hardening_(metallurgy)

    This is simply an effect of another deformation mechanism that becomes easier, i.e. grain boundary sliding. At this point, all dislocation related hardening mechanisms become irrelevant. [1] In work hardening (also referred to as strain hardening) the material is strained past its yield point, e.g. by cold working. Ductile metal becomes harder ...

  6. Ceramic - Wikipedia

    en.wikipedia.org/wiki/Ceramic

    Drawbacks to ceramic bearings include significantly higher cost, susceptibility to damage under shock loads, and the potential to wear steel parts due to ceramics' greater hardness. In the early 1980s Toyota researched production of an adiabatic engine using ceramic components in the hot gas area. The use of ceramics would have allowed ...

  7. Chrome plating - Wikipedia

    en.wikipedia.org/wiki/Chrome_plating

    Decorative chrome is designed to be aesthetically pleasing and durable. Thicknesses range from 2 to 20 μin (0.05 to 0.5 μm), however, they are usually between 5 and 10 μin (0.13 and 0.25 μm). Thicknesses range from 2 to 20 μin (0.05 to 0.5 μm), however, they are usually between 5 and 10 μin (0.13 and 0.25 μm).

  8. Chemical milling - Wikipedia

    en.wikipedia.org/wiki/Chemical_milling

    A high-purity (≥99.9998%) aluminium bar that has been etched to reveal the component crystallites. Chemical milling or industrial etching is the subtractive manufacturing process of using baths of temperature-regulated etching chemicals to remove material to create an object with the desired shape.

  9. Artificial stone - Wikipedia

    en.wikipedia.org/wiki/Artificial_stone

    Artificial stone is a name for various synthetic stone products produced from the 18th century onward. Uses include statuary, architectural details, fencing and rails, building construction, civil engineering work, and industrial applications such as grindstones .
