The erosion-corrosion behaviour of low-temperature plasma surface alloyed AISI 316 austenitic stainless steel has been compared with untreated material using a newly developed slurry pot erosion-corrosion apparatus containing a slurry comprising 20 wt.% silica sand and 3.5%NaCl at 40 β’ C. The total
a b s t r a c t 17-4PH stainless steel was plasma nitrocarburized at 430 β’ C for different time with rare earths (RE) addition. Plasma RE nitrocarburized layers were studied by optical microscope, scanning electron microscope equipped with an energy dispersive X-ray analyzer, X-ray diffraction, micr
