PARTICULAS ABRASIVAS DE CARBONETO DE SILICIO COM REVESTIMENTO MULTICAMADA |
| 摘要 |
Ceramic particles (18) useful as abrasives in a metal matrix layer are described. The particles are coated with an oxide monolayer (30) and a metal duplex layer. Preferably, the particles are silicon carbide; the oxide monolayer is aluminum oxide, and the metal duplex layer is a nickel-boron alloy (32) over pure nickel (31). |
