the present invention can include several different powder blends or in addition to the powder blend blends one or more separately produced powders having a uniform composition and partly or totally compact materials whereby so called compound materials can be formed this makes it possible to further improve the wear resistance and impact resistance of the materials and components if more than one powder blend is used the different powder blends must be separated from each other with thin sheets or foils when a compact or partly compact material is used it in not necessary to separate it from the powder blend iron based martensitic powder including carbides nitrides and carbonitrides should include enough alloying elements such as chromium or molybdenum in order to achieve an adequate hardenability and mainly a martensitic microstructure after the heat treatment in addition to martensite and precipitates the powder might include a small amount of austenite by alloying the powder in question adequately with e g chromium molybdenum and vanadium in a suitable proportion together with carbon and nitrogen carbides nitrides and carbonitrides can be incorporated into the microstructure for improving the abrasion resistance the martensitic precipitate containing powder should include alloying elements forming carbides nitrides and carbonitrides in an amount of at least 8 weight percent most preferably from 10 to 20 weight percent and carbon and nitrogen at least 0 8 weight percent most preferably from 1 8 to 3 6 weight percent the nitrogen can be alloyed with the molten metal prior to atomization during the gas atomization by using nitrogen as atomization.
