Metallisches Pulver für die Erzeugung von verschleißfesten Oberflächenschichten mittels einer thermischen Spritzmethode, Herstellungsverfahren und Spritzmethode dafür

摘要

The invention relates to a metallic powder for making wear-resistant surface layers by means of a thermal spray process, which powder consists of one or more transition metals, in particular predominantly of nickel or iron, and in each case chromium as alloy element and which, in addition, contains at least one metalloid, especially boron, carbon, silicon or phosphorus. The characterising feature of the powder is that the powder grains contain occlusions which consist of sintered particles derived from the particular metalloid. The invention also relates to a preparation process for the powder and to a preferred application technology.
