Surface modification is an essential step in engineering materials that can withstand the increasingly aggressive environments encountered in various modern energy-conversion systems and chemical processing industries. However, most traditional technologies exhibit disadvantages such as slow diffusion kinetics, processing difficulties or compatibility issues. Here, we present a general strategy...
In this study, the effect of platinum-aluminide coating parameters on surface roughness of nickel-based superalloy Rene®80 was evaluated. For this purpose, different thicknesses of Pt-layer (2, 4, 6 and 8µm) were plated on the Samples. Then diffusion aluminide coating in two types, high tempeature-low activity and low temperature-high activity was performed. The results of structural investigat...
Due to their excellent mechanical properties, Co-based alloys are one of the main candidates replace Ni-based in high temperature application. Knowledge about oxidation resistance alloy MAR M-509 and extent its aluminizing on is limited. Therefore, present study, an aluminide layer was manufactured by low activity chemical vapor deposition (LA-CVD) M-509. Aluminized uncoated were investigated t...
