Abstract: A process for producing a sintered spraying powder comprising chromium nitride includes producing a powder mixture comprising a first powder and a second powder, and sintering the powder mixture to the sintered spraying powder at a nitrogen partial pressure of >1 bar so as to maintain or increase a chemically bound nitrogen in the sintered spraying powder compared to a chemically bound nitrogen in the first powder mixture. The first powder comprises at least one constituent selected from the group consisting of Cr, CrN and Cr2N. The second powder comprises at least one constituent selected from the group consisting of nickel, cobalt, nickel alloys, cobalt alloys and iron alloys.

Abstract: A process for producing a chromium nitride-containing spraying powder includes providing an alloy powder comprising at least 10 wt.-% of chromium, and at least 10 wt.-% of at least one element selected from transition groups IIIA to IIB of the Periodic Table of Elements and B, Al, Si, Ti, Ga, C, Ge, P and S. The alloy powder is nitrided in the presence of nitrogen so as to form at least one of CrN and Cr2N.
