<p>A boron-containing matrix alloy is mixed with an additive material of higher melting point, such as molybdenum, the particles of the additive material being spherical, in the grain size range from 20-150 mu m and constituting 30-80 percent by weight of the mixture. A protective layer or coating produced therefrom by flame-spraying, with simultaneous fusion, provides very good anti-friction properties with simultaneously a very high resistance to wear.</p> |
