  2. Surface modification - Wikipedia

    en.wikipedia.org/wiki/Surface_modification

    Surface modification is the act of modifying the surface of a material by bringing physical, chemical or biological characteristics different from the ones originally found on the surface of a material. [1] This modification is usually made to solid materials, but it is possible to find examples of the modification to the surface of specific ...

  3. Corona treatment - Wikipedia

    en.wikipedia.org/wiki/Corona_treatment

    Corona treatment (sometimes referred to as air plasma) is a surface modification technique that uses a low temperature corona discharge plasma to impart changes in the properties of a surface. The corona plasma is generated by the application of high voltage to an electrode that has a sharp tip. The plasma forms at the tip.

  4. Severe plastic deformation - Wikipedia

    en.wikipedia.org/wiki/Severe_Plastic_Deformation

    The NC surface layer developed can be on the order of 50 μm thick. [10] The process is similar to shot peening, but the kinetic energy of the balls is much higher in SMAT. [22] An ultrasonic nanocrystalline surface modification (UNSM) technique is also one of the newly developed surface modification technique.

  5. Silanization - Wikipedia

    en.wikipedia.org/wiki/Silanization

    Almost always, silanization is the conversion of a silanol-terminated surface to a alkylsiloxy-terminated surface. This conversion confers hydrophobicity to a previously hydrophilic surface. [ 1 ] [ 2 ] This process is often used to modify the surface properties of glass, silicon, alumina, quartz, and metal oxide substrates, which all have an ...

  6. Surface engineering - Wikipedia

    en.wikipedia.org/wiki/Surface_engineering

    Surface engineering is the sub-discipline of materials science which deals with the surface of solid matter. It has applications to chemistry , mechanical engineering , and electrical engineering (particularly in relation to semiconductor manufacturing ).

  7. Plasma activation - Wikipedia

    en.wikipedia.org/wiki/Plasma_activation

    Plasma activation (or plasma functionalization) is a method of surface modification employing plasma processing, which improves surface adhesion properties of many materials including metals, glass, ceramics, a broad range of polymers and textiles and even natural materials such as wood and seeds. Plasma functionalization also refers to the ...

  8. Carbonitriding - Wikipedia

    en.wikipedia.org/wiki/Carbonitriding

    Carbonitriding is a metallurgical surface modification technique that is used to increase the surface hardness of a metal, thereby reducing wear. During the process, atoms of carbon and nitrogen diffuse interstitially into the metal, creating barriers to slip , increasing the hardness and modulus near the surface.

  9. Surface finishing - Wikipedia

    en.wikipedia.org/wiki/Surface_finishing

    Also known as a mirror finish. This finish is produced by polishing with at least a 320 grit belt or wheel finish. Care will be taken in making sure all surface defects are removed. The part is sisal buffed and then color buffed to achieve a mirror finish. The quality of this finish is dependent on the quality of the metal being polished.
