Electroless metallization of sic after laser ablation

At higher energy densities the ablated areas contain Si oxide. The non-stoichiometric ablation of SiC allows one to activate selectively the SiC surface for metal deposition from electroless plating solution. Both Ni and Cu deposits show excellent adherence to both SiC ceramics and single-crystal SiC.

Abstract. Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes.

Thin film - Wikipedia

2019-4-23 · A thin film is a layer of material ranging from fractions of a nanometer to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many appliions. A familiar example is the mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface.
