Cr3C2-NiCr coatings have been used for corrosion and wear resistant applications. In thelast decade, thermal sprayed coatings using nanostructured feed stock of other materials hasexhibited higher hardness, strength and corrosion resistance. Hence, it is anticipated thatnanostructured Cr3C2-NiCr coatings will also exhibit these properties and therefore possesimproved performance characteristics. Preparation of nanostructured feed stock powders is the firststep in the synthesis of nanostructured coatings and mechanical milling is an effective process toobtain the powders. Preliminary studies in which commercial Cr3C2-NiCr powders were milled inhexane and gaseous nitrogen revealed that particle and crystallite size were significantly smaller inpowders milled in nitrogen. This paper presents the effect of hexane content and milling parameterson Cr3C2-Ni20Cr powder characteristics. Use of just sufficient hexane as the milling media reducedsignificantly the particle and crystallite sizes
