A typical substrate might be rigid such as metal, concrete, or glass, onto which a coating might be deposited. Flexible substrates are also used. [1] Some substrates are anisotropic with surface properties being different depending on the direction: examples include wood and paper products.
Wood's metal. Wood's metal, also known as Lipowitz's alloy or by the commercial names Cerrobend, Bendalloy, Pewtalloy and MCP 158, is a metal alloy that is useful for soldering and making custom metal parts, but its fumes are toxic, as well as being toxic on skin exposure. The alloy is named for Barnabas Wood, who invented and patented the ...
The term mokume-gane translates closely to 'wood grain metal' or 'wood eye metal' and describes the way metal takes on the appearance of natural wood grain. [1] Mokume-gane fuses several layers of differently coloured precious metals together to form a sandwich of alloys called a "billet." The billet is then manipulated in such a way that a ...
Metal composite material (MCM) is a type of sandwich formed from two thin skins of metal bonded to a plastic core in a continuous process under controlled pressure, heat, and tension. [ 3 ] Recycled paper is also now being used over a closed-cell recycled kraft honeycomb core, creating a lightweight, strong, and fully repulpable composite board.
Composite wood such as glulam and plywood with wood glue as a binder; Reinforced plastics, such as fiberglass and fibre-reinforced polymer with resin or thermoplastics as a binder; Ceramic matrix composites (composite ceramic and metal matrices) Metal matrix composites [2] advanced composite materials, often first developed for spacecraft and ...
In casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process. Once the pattern has been used to form the sand mould cavity, the pattern is then removed, molten metal is then poured into the sand mould cavity to produce the casting.
Making Bakelite is a multi-stage process. It begins with the heating of phenol and formaldehyde in the presence of a catalyst such as hydrochloric acid, zinc chloride, or the base ammonia. This creates a liquid condensation product, referred to as Bakelite A, which is soluble in alcohol, acetone, or additional phenol. Heated further, the ...
For example, juiceboxes are fabricated from liquid packaging board which is usually six layers of paper, polyethylene, and aluminum foil. Paper is used in the lamination to shape the product and give the juicebox an extra source of strength. The base is most often particle- or fiberboards, then some layers of absorbent kraft paper.
