Abstract
Bulk metallic glasses (BMGs) have gained a lot of attention in recent years due to their outstanding properties such as high hardness and excellent wear and corrosion resistance. However, they are restricted in industrial applications due to their extreme brittleness. Iron based amorphous coatings from BMGs are the best solution to use them by overcoming the problem of extreme brittleness. The coatings can be sprayed by various thermal techniques such as flame spraying (FS), high velocity air fuel (HVAF), High velocity oxy fuel (HVOF) spraying process and plasma spray (PS) process. In this study, we have developed iron-based amorphous coating via HVOF and found interesting effect of structural relaxation at low temperature. Iron-based amorphous alloy powder with Fe48Mo14Cr15Y2C15B6 composition was used as the feedstock powder. The coatings sprayed by HVOF the techniques showed compact coatings as observed by the Scanning electron microscopy (SEM) results and amorphous phase was confirmed by the X-ray diffraction analysis at various temperature. Further investigations on the mechanical properties and chemical properties show that low temperature sintering improve the property of coatings.
