Process for the production of silicon carbide abrasive-water-jet nozzle. |
摘要 |
<p>A tube (1) is formed from a polycrystalline silicon carbide having a density of from 3.18 to 3.21 g/cm<3>, a maximum impurity content of 20 ppm, and imperviousness to fluids by a process which comprises precipitating the silicon carbide (1a) on the surface of a rod-shaped graphite structure (G) by a chemical vapor-phase synthesis method and thereafter removing the graphite structure. A water-jet nozzle of high resistance to abrasive wear can be produced by using this tube as an inner tube thereof to form the flow path for a water jet to be ejected therethrough.</p> |
