Effect of ZrSiO_4 on the Friction Performance of Automotive Brake Friction Materials

Journal of Materials Science & Technology 2007年第6期23卷 843-850页

作者： Mustafa BOZ Adem kurt Metallurgy Department Z.K.U.Karabük Technical Education Faculty78200 KarabükTurkey Metallurgy Department Gazi UniversityTechnical Education Faculty06500 AnkaraTurkey

Friction-wear properties of the ZrSiO4 reinforced samples were measured and compared with those of plain bronze based ones. For this purpose, density, hardness, friction coefficient wear behaviour of the samples were tested. Microstructures of samples before and after sintering and worn surfaces were also investigated by scanning electron microscopy （SEM）, and the wear types were determined. The optimum friction-wear behaviour was obtained in the sample compacted at 500 MPa and sintered at 820℃. Density of the final samples decreased with increasing the amount of reinforcing elements （ZrSiO4） before pre-sintering. However after sintering, there is no change in density of the samples including reinforcing elements （ZrSiO4）. With increasing friction surface temperature, a reduction in the friction coefficient of the samples was observed. However, the highest reductions in the friction coefficients were observed in the as-received samples containing 0. 5% reinforced ZrSiO4. The SEM images of the sample indicated that while bronze-based break lining material without ZrSiO4 showed abrasive wear behaviour, increasing the amount of ZrSiO4 resulted a change in abrasive to adhesive wear mechanism. All samples exhibited friction-wear values, which were within the values shown in SAE-J661 standard. With increasing the amount of reinforcing ZrSiO4, wear resistance of the samples was increased. However samples reinforced with 5% and 6% ZrSiO4 showed the best results.

Effect of Different Amounts of Graphite on the Sintering and Transverse Rupture Properties of Powder Metal Parts

引用

Journal of Materials Science & Technology 2006年第3期22卷 419-422页

作者： Mustafa Boz Adem kurt Karabuk Technical Education Faculty Zonguldak Karaelmas University Karabuk 78050 Turkey Technical Education Faculty Gazi University Besevler 06500 Ankara Turkey

Iron powders were mixed with graphite powders by 1-15 wt pct to produce block samples using powder metallurgy technique. The powders were blended in a three dimensional blender for 20 min and compacted in a die under 500 MPa by using a one directional press. Sinterability and mechanical properties of the samples with different carbon content were investigated. Sintering process was carried out on a belt furnace with flame curtain in dissociated ammonia atmosphere. Block samples produced were suitable for ASTM B-312 transverse rupture strength test apparatus and were tested with 0.050 kN/s velocity in a press under 100 g load. It was found that graphite amount up to 2 wt pct increased the contact area of particles and acted as a lubricant to affect the sintering behaviour positively. The results indicated that the samples containing up to 5 wt pct showed good sintering behaviour and also good hardness due to an increase in pearlite amount. However, the samples containing higher amount of graphite （more than 5 wt pct） affected the sintering behaviour negatively due to the settlement of free graphite around the Fe powders, which resulted in a decrease in the hardness and transverse rupture strength.

Interfacial Microstructure of Diffusion Bonded Inconel 738 and Ferritic Stainless Steel Couple

引用

Journal of Materials Science & Technology 2009年第4期25卷 527-530页

作者： Bulent kurt Mustafa Ulutan Bartin University Faculty of EngineeringDept.of Metallurgical and Materials Engineering University of Eskisehir Osmangazi Faculty of EngineeringDept. of Mech.Eng

In this study, Inconel 738 alloy was diffusion bonded to a ferritic stainless steel. The effect of bonding temperature on the microstructural development across the joint region was investigated. Following the diffusion bonding, conventional characterization techniques such as scanning electron microscopy （SEM）, energy dispersive X-ray （EDX） and microhardness were used to examine the interracial microstructure. It was seen that bonding temperature was effective on the diffusion of Ni from Inconel 738 to ferritic stainless steel that affected the microstructure of the interface. Austenite phase was formed at the interface as a result of Ni diffusion from the Inconel 738 to the interface.

Land use changes in Istanbul＇s Black Sea coastal regions between 1987 and 2007

引用

Journal of Geographical Sciences 2013年第2期23卷 271-279页

作者： Sumeyra kurt Istanbul University Department of Geography 34452 Beyazlt Istanbul Turkey

Recently, important land use changes have occurred in the Black Sea coastal regions of istanbul due to urban growth and population increases. The objective of this study was to determine changes in land use in the Black Sea coastal regions of Jstanbul between 1987 and 2007. Landsat 30 m satellite images from 1987 and 2007 are used in the study. The study area is 1000 m in width from the coastline to the land and the study has been carried out using the controlled classification method to classify areas into residential, agricultural, forest, bare land, brush/grassland, and lake/pond land classes. Land use changes between 1987 and 2007 were analysed in detail. Residential areas of the Black Sea coastal regions of istanbul increased by 122% over the two decades. Also an increase of 55% in agriculture areas was observed, while there were decreases of 26% in forest areas and 15% in free land. A 21% increase in the area of brush and grassland took place. Furthermore 79% of the study area was covered by residential areas in 2007. It is probable that pressure on the Jstanbul coastal regions will continue due to migraton and rapid urbanization. Therefore, Istanbul＇s Black Sea coastal regions should be maintained using a sustainable coastal management plan.

Research on the many aspects of the plant cell wall has experienced reiuvenation during the past few years. This is perhaps mainly due to the commercial interest in the chemical components of the cell wall that have potential for industrial use＂ Cellulose for fibers and together with hemicelluloses for bioethanol, lignin for plastics or biofuel, pectins as gel agents, let alone woody cell wall material for construction or pulp production and for intelligent materials for electronics - the new uses are mindboggling!
