Tape casting (also called doctor blading, knife coating, and shank shifting) [1] is a casting process used in the manufacture of thin ceramic tapes and sheets from ceramic slurry. [2] The ceramic slurry is cast in a thin layer onto a flat surface and then dried and sintered. [3] It's a part of powder metallurgy. [4]: 167
A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound. These coatings are commonly applied to protect the part against corrosion , to improve the adherence of other coatings, for lubrication , or for aesthetic ...
Indium tin oxide (ITO) is an optoelectronic material that is applied widely in both research and industry. ITO can be used for many applications, such as flat-panel displays, smart windows, polymer-based electronics, thin film photovoltaics, glass doors of supermarket freezers, and architectural windows.
This surface could be used to produce new film or layers of material such as deposited coatings. It could be the base to which paint, adhesives, or adhesive tape is bonded. A typical substrate might be rigid such as metal, concrete, or glass, onto which a coating might be deposited.
The photoresist is removed in the areas, where the target material is to be located, creating an inverse pattern.) Target material (usually a thin metal layer) is deposited (on the whole surface of the wafer). This layer covers the remaining resist as well as parts of the wafer that were cleaned of the resist in the previous developing step.
The processed surface is then coated with electroless copper or nickel before further plating. This process gives useful (about 1 to 6 kgf/cm or 10 to 60 N/cm or 5 to 35 lbf/in) adhesion force, but is much weaker than actual metal-to-metal adhesion strength. Vacuum metallizing involves heating the coating metal to its boiling point in a vacuum ...
An X-cut is made through the film with a carbide tip tool to the substrate. Pressure-sensitive tape is applied over the cut. Tape is smoothed into place using a pencil eraser over the area of the incisions. Tape is removed by pulling it off rapidly back over itself as close to an angle of 180°. Adhesion is assessed on a 0 to 5 scale.
Upwords is a letter tile word game similar to Scrabble, with players building words using letter tiles on a gridded game board. Unlike Scrabble, in Upwords letters can be stacked on top of existing words to create new words. Scoring is determined by the number of letter tiles, including tiles in a stack, in a new word.
