Process parameter impact on microstructure of laser clad inconel-chromium carbide layers
2012 (English)In: Materials Science Forum, ISSN 0255-5476, E-ISSN 1662-9752, Vol. 702-703, 963-966 p.Article in journal (Refereed) Published
Chromium carbide based metal matrix composite (MMC) coatings are ideally suited for high temperature erosive-corrosive applications. Laser cladding of such MMCs, with Inconel as the ductile matrix instead of the usual NiCr alloy, has been attempted in the present study. The relative hardness of the laser clad layers was observed to drop with increase in laser power. The reduction in hardness was attributed to retention of lower amounts of chromium carbides in the clad layer at higher laser powers. Use of chemically assisted scans with electron diffraction allowed extraction of effective micro-textural information on the coatings. © (2012) Trans Tech Publications, Switzerland.
