A composite coating of WC/Hadfield steel was fabricated through centrifugal casting process to improve the impact wear resistance of Hadfield steel under the conditions of low or medium impact energy. The interfacial structure between WC ceramic particle and the steel matrix was analyzed with scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD)...
The high temperature oxidation tests of Ni-Cr alloys which containing different alloying elements such as Mo, W, B, Cr and Ni were carried out through placing the specimen in a muffle for 100h at 800 o C. In order to determine the effect of oxidation on the wear behavior of the alloys at elevated temperature, an interrupted oxidation-abrasion wear test was carried out on a high temperature...
In this study, Na 2 SiO 3 , Na 2 MoO 4 , (NH 2 )NS and (NaPO 3 ) 6 were selected as inhibitors to slow down the corrosion of gray iron in distilled water. Furthermore, the wear tests of Si 3 N 4 -gray iron pair lubricated with these inhibited solutions were carried out on a ring-block tester. The worn surfaces of specimens were...
