Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. [1] Finishing processes may be ...
Surface reaction of the precursor subspecies results in the incorporation of elements into a new epitaxial layer of the semiconductor crystal lattice. In the mass-transport-limited growth regime in which MOCVD reactors typically operate, growth is driven by supersaturation of chemical species in the vapor phase. [ 4 ]
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.
The multitude of such primary impact craters generates a texture and surface which in visual cleanliness and roughness (anchor profile) mimics those obtained by grit blasting processes. [2] The cleaned and coarsened surface is deemed favorable for the subsequent application and adhesion of protective films and industrial coatings. [3]
Laser peening (LP), or laser shock peening (LSP), is a surface engineering process used to impart beneficial residual stresses in materials. The deep, high-magnitude compressive residual stresses induced by laser peening increase the resistance of materials to surface-related failures, such as fatigue, fretting fatigue, and stress corrosion cracking.
Surface micro-machining involves as many layers as are needed with a different mask (producing a different pattern) on each layer. Modern integrated circuit fabrication uses this technique and can use as many as 100 layers. Micro-machining is a younger technology and usually uses no more than 5 or 6 layers.

Applying innovative surface engineering technologies to the energy sector has the potential of reducing annual CO 2-eq emissions by up to 1.8 Gt in 2050 and 3.4 Gt in 2100. This corresponds to 7% and 8.5% annual reduction in the energy sector in 2050 and 2100, respectively. [ 1 ]
