Mechanical properties and wear resistance of ultrafine bainitic steel under low austempering temperatureWei Liu1,You-hui Jiang1,Hui Guo2,Yue Zhang1,Ai-min Zhao1,Yao Huang31. Collaborative Innovation...:The mechanical properties and wear resistance of the ultrafine bainitic steel austempered at various temperatures were investigated.Scanning electron......
Wear Resistance of Two Nanostructural Bainitic Steels with Different Amounts of Mn and NiSaman Ahmadi Miab1,Behzad Avishan2,Sasan Yazdani11. Faculty of Materials Engineering, Sahand University... with acceptable wear resistance can make nanostructural bainitic steels to be used extensively in different engineering and tribological applications. However, it is critical to characterize the contributed factors......
decreases the wear loss. The wear resistance of the composites increases as the graphite particle size increases. At low load the composites have similar wear loss; at high load the composite with the largest graphite particle size has the best wear resistance. The wear mechanism of all the composites at low load is abrasive wear and oxidation wear; at high load, except the composites with the particle......
at the contact interface is prevented. Besides, the hardness and wear resistance of the reinforcement phase are markedly high, thus the reinforcement phase has grinding and micro- scoring effect... well with either tensile ductility or hardness. It is determined by the relative wear resistance of the matrix and particulates and also by the nature of the interface layer that forms between......
Influence of Ta on Microstructure and Abrasive Wear Resistance of Laser Clad NiCrSiB Coating余廷1,2,DENG Qilin2,DONG Gang3,YANG Jianguo21. School of Mechanical and Electrical Engineering, Nanchang... of NiCrSiB alloy powder and tantalum (Ta) powder was used as laser clad material to improve abrasive wear resistance of the Ni-based coating. The microstructure and wear resistance of the coating were......
Influence of Re-Ti modification on the high impact wear resistance of high Si bainitic cast steelJin-feng Huang1), Hong-sheng Fang2), and Yan-kang Zheng2) 1) State Key Laboratory for Advanced Metals.... The experiments show that the impact wear resistance can be improved greatly with the addition of Re and Ti. Its wear loss is only about 1/3-1/2 as large as that of the unmodified bainitic cast steel. By the Re......
Thickness effects on corrosion and wear resistance properties of micro-arc discharge oxide coatings on AZ91D magnesium alloys HUANG Wei-jiu(黄伟九), LIU Ming(刘 明), LI Zhao-feng(李兆峰), ZENG Rong... of the MAO coatings is four to six times higher than that of the magnesium alloy substrate. The MAO coatings have much better wear-resistance and corrosion resistance abilities than those of magnesium......
resistance due to the homogeneous reinforcement distribution with small pore size; on the contrary, under high load, the composite with high reinforcement volume fraction exhibits better wear resistance because of the coarse frame size. Hard SiC frame leads to the wear of Cr12 steel mainly. The frame with high volume fraction corresponds to the high Fe content. Key words: continuous......
