Carborundum Mezzotint and Carborundum Etching

The carborundum mezzotint process involves abrading the surface of a metal plate with particles of carborundum under the pressure of a hand-rotated weight (fig. 26). The resulting surface becomes uni-formly pitted, allowing the entire plate to hold ink. A

Dox Thrash: Creator of Opheliagraph - SAIC

Many lauded the carborundum process—at that time, the first new printmaking method in more than 100 years—but did not name Thrash as its pioneer. Today, neither Dox Thrash nor the carborundum print are names. Perhaps that would be different if the press had taken note of what Dox Thrash himself named his printmaking process.

Acheson process - Wikipedia

The first commercial plant using the Acheson process was built by Acheson in Niagara Falls, New York, where hydroelectric plants nearby could cheaply produce the necessary power for the energy intensive process. By 1896, The Carborundum Company was producing 1 million pounds of carborundum. Many current silicon carbide plants use the same basic design as the first Acheson plant.

Tungsten Carbide Thermal Spray | Tungsten Spray Coatings

Tungsten carbide coatings are achieved through the HVOF thermal spray process. Within this process fuel gas and oxygen are combusted in a high-pressure chamber reaching temperatures up to 5,600°F (3,093°C). The resulting hot, high-pressure gas is ejected through a small-diameter nozzle and accelerated down a long barrel at supersonic speeds.
