    Notes: This paper presents a cost-effective technique for achieving optical surface finish ofthermally stable polycrystalline diamond (PCD) composites using dynamic friction polishing(DFP). The effect of polishing parameters on the material removal rate and surface characteristicsof polished specimens were studied. The surface characterisation was carried out by opticalmicroscopy, atomic force microscopy (AFM), scanning electron microscope (SEM) and its attachedenergy dispersive X-ray (EDX) analysis. It was found that optical surface finish of PCD withroughness Ra = 50 nm could be obtained efficiently with nearly a ten fold reduction in polishingtime compared to the currently used method in industry

    Notes: Utilize the characteristic that magnetic force line may penetrate the non-magneticmaterial, using the magnetic abrasive finishing (MAF) method complete to the non-magnetic smallworkpiece surface precise processing. In order to enhance polishing efficiency, usually with themagnetic particles and abrasive particles mixes together in the sinter method or the cementationmethod, the cost is higher; the variety is not also complete. Therefore, use the simply mixed methodmixed the ferromagnetism iron particles, the alumina particles and the lipin, directly participates inmagnetism polishing, already obtained the good processing effect through the experiment. Thispaper analysis and explanation the best experimental condition such as the granularity proportion ofthe ferromagnetism iron particles and the alumina particles etc

    Compressive Properties of Porous Metals with Homogeneous Pore Characteristics (2007)

    Notes: Spacer method is excellent technique of processing porous metals with well-controlledpore characteristics such as porosity (up to 90%) and pore size (as small as several hundredmicrometers). Compressive properties of porous aluminum fabricated by the spacer method areinvestigated. They were subjected to monotonic compression tests at room temperature, and showedless fluctuated flow stress during their compressive deformation than conventional porous aluminumalloy, reflecting their homogeneous pore characteristics. Also, shortening behavior of the porousaluminum fabricated by the spacer method during cyclic compression was significantly differed fromthat of conventional porous aluminum alloy. Therefore, it can be concluded that the homogeneity ofpore characteristics is responsible for compressive properties of porous metals. Monotoniccompression tests on porous copper specimens with various porosities, which were made by thespacer method, were also conducted. The yield stress of the porous copper with high porosity (or lowrelative density) depended on the relative density more strongly than that of the porous copper withlow porosity (or high relative density). It is presumed that porous metals with high porosity and oneswith low porosities have different deformation mechanisms

    Kinetics of Interfacial Reaction in SiC〈sub〉f〈/sub〉/Ti6Al4V Composites (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: The Ti6Al4V composites reinforced with Chinese SiC fiber was manufactured and thenthermally exposed at 800°C, 900°C and 1000°C, respectively, for up to 500h. The interfacial reactionproducts were identified as TiC between Ti6Al4V and the C-coating of the SiC fiber. However, if theSiC fiber has no C-coating, the interfacial reaction forms TiC, Ti3SiC2, Ti5Si3(Cx) and Ti3Si(Cx). Thethickness of the interfacial reaction zone was measured and it is found that the thickening rate isslower in the samples in which the SiC fiber has the C-coating. The growth of the interfacial reactionproducts is diffusion-controlled and the parameters of the growth kinetics, k0 and Q, were determined,respectively. The profile of the element distribution was calculated according to the diffusion theoryand is well consistent with the expeimental data

    Notes: Because of the raw material elements and its purity and so on, the Nd-Fe-B permanent magnet,the strongest magnetic material, which needs artificial synthesis, can hardly be used directly. Theperformance of the permanent magnet has not yet been greatly developed owing to the limitation of theartificial synthesizing technology, of the powder sintering technology and that of the application. In thispaper, the magnetic abrasive machining method as a new application is put forward, and from thisviewpoint, are discussed the performance and the processing technology of the permanent magnet and themagnetic abrasive machining method. A sintering route combining the direction heat treatment techniqueto increase the magnetic energy is suggested
