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 ...
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 ...
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.
In 2015, the "Hertz Application Laboratory" (today: Hertz Electron Beam Laboratory) and the installation of a 10 MeV electron accelerator created an infrastructure that is unique in Germany for basic research in the field of materials science and for industry-related projects on material modification using high-energy electrons (up to 10 MeV).

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.
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.
Surface Treatments and Coatings; Applying surface treatments or coatings can modify the interfacial energy of grain boundaries. Surface modification techniques, such as chemical treatments or deposition of thin films, can alter the surface energy and consequently affect the grain boundary energy. [10] Heat Treatments and Annealing
In friction stir processing (FSP), a rotating tool is used with a pin and a shoulder to a single piece of material to make specific property enhancement, such as improving the material's toughness or flexibility, in a specific area in the micro-structure of the material via fine grain of a second material with properties that improve the first.(Ma) [6] Friction between the tool and workpieces ...
