Effect of Al content on high temperature erosion properties of arc-sprayed FeMnCrAl/Cr3C2 coatings LUO Lai-ma(罗来马)1, LIU Shao-guang(刘少光)2, YU Jia(俞 佳)1, LUO Juan(罗 娟)1, LI Jian(郦 剑)1 1... were analyzed by optical microscopy (OM) and X-ray diffractometry (XRD). High temperature erosion (HTE) tests were performed in an erosion tester at different impact angles. The surface morphologies......
, Cr, Fe, C and Si. It is obvious from the erosion test that the Ni60A/SiC coating has high erosion resistance. Key words: laser cladding; Ni60A; SiC; erosion resistance high strength, good process property, high wear resistance, erosion resistance, heat resistance and so on, showing many engineering......

Review of SiCf/SiCm corrosion, erosion and erosion-corrosion in high temperature helium relevant to GFR conditions [J..., there has been strong interest in optimizing their ingredients and microstructures to develop the erosion resistance [23]. Ductile Al modified C/C-SiC composites have lower preparation temperature [24......
. It can provide high-quality erosion protection for these materials. The implanted polyimide fully restores its original color and the carbonization effect disappears on the whole after AO exposure... pulse-biased to 40 kV with a pulse width of 15 ?s and repetition rate of 100 Hz. The implantation current was about 1 A per pulse. The sample temperature was below 150 ℃. 2.2 AO erosion facility......

Influence of austenization temperature on the erosion behavior of austempered ductile ironsI.C.Hsui摘 要:<正>The erosion behavior of austempered ductile irons austenized at different temperatures was studied.The results indicate that the erosion rate well correlates with the mechanical properties.At high impact angles,increasing ductility......
was used to discover the influences of temperature, time and surface conditions on the erosion resistance of H13 steel. The interfaces between the steel and the molten alloy were studied with optical microscopy to compare the different erosion resistance behaviours. The results show that the composite layer outside of the compounds layers changes obviously with increasing temperature, lasting time......
was remarkable, sandy soils on the bottom area of the windward slope still maintained a relatively high level of surface strength and a low degree of wind erosion 12 month after SICP treatment... the world [1]. Wind erosion is a major cause of desertification and sandstorm in arid and semi-arid areas. Sandy soils in these regions have low cohesion and loose structure. During the dry season, high......
Effect of sintering temperature on morphology and arc erosion properties of La-Ni-O ceramic and its composites尹娜,王洪超,王春雷摘 要:Ceramic LaNiO3 samples were... of the samples. X-ray diffraction(XRD) patterns of ceramics before and after arc erosion indicated their high structural stability,which resulted in the good arc erosion resistance properties for silver......
