WebThe most commonly used additive is the silicon dioxide (silica) which has a rod-shape morphology and an average particle size of approximately 15 nm. Apart from the primary objective being to improve the mechanical properties, this additive can also improve the optical properties as well [10].
WebIn the broadest sense, additive manufacturing is a process for creating 3D objects directly from CAD (computer aided design) files. While there are quite a variety of additive techniques, they all share a common approach. First, the system software renders the object design into a series of slices, and then controls a machine that deposits ... WebBright plating baths contain additives that are called brighteners. There are a large number of different kinds of these compounds. They enhance both the leveling and brightening abilities of a bath at wide current density range. Often, a brightener system is used, which consists of primary and secondary brighteners.
