Evaluation of tool wear when milling SiCp/Al Composites
S.T.
Milling is another important machining method for SiCp/Al composites, but there are few works related to the influence of milling characteristics of SiCp/Al composites, especially for the high volume fraction SiCp/Al composites.
The experimental material is CY1110 SiCp/Al composites.

Chmiola et al. found an irregular increase in specific capacitance when the electrode materials have a surface area and pore structure suitable to the ion diameter of the electrolyte [4].
Sulphoric acid (99%, EDWIC, El Nasr Pharmaceutical chemicals) was used as electrolyte.

All metallic sheet surfaces were pretreated with an AC-130 sol-gel post-treatment after corundum-blasting with 105 μm particles and then added to the laminate stacking within one hour, as described by Stefaniak et al. [2].
Xue et al. [9] is used for the present investigations.
The advantages of the bilinear model or MVF-approach (Metal-Volume-Fraction-approach) for preliminary investigation are simplicity and also its predictions of laminate stiffness EL and yield strength σL,y are quite accurate [4].
The laminate’s longitudinal stiffness EL and the thermal expansion coefficient in fiber direction αL can be predicted by the rule of mixture as a function of the metal volume fraction φm [11].
After the yield point of the steel is exceeded, the laminate´s longitudinal stiffness EL,pl decreases due to the change in rigidity of the metal.

For example, Ren et al. (2009) [7] found that the tensile strength and elongation at break of TPS (corn starch)/PBAT film (50:50) could be improved after adding anhydride functionalized polymer (1wt%) as a compatibilizer.

All organic layers were grown on the amorphous IZO and
commercial ITO anode by thermal evaporation at 1×10
-7 Torr in the following order: hole transporting
layer (HTL)/emission layer (EL)/hole blocking layer (HBL)/electron transporting layer (ETL)/electron
injection layer (EIL) 40 nm-thick α-napthylphenlylbiphenyl (NPB) and 30 nm-thick
4,4'-bis(9-carbazolyl)-biphenyl (CBP) doped with 6 wt %[Ir(ppy)3] were used as the HTL and EL,
respectively.
Subsequently, a 10 nm-thick 2,9-Dimethyl-4,7-diphenyl-1,10-phenanthroline (bathocuproine: BCP) layer was grown on the EL layer as a HBL layer.
Finally, a 100 nm-thick Al cathode layer was patterned using a shadow metal mask.
He et al., in an investigation of the p-i-n structure of an OLED, reported improved EQE (19.5%) when a double emission layer (TCTA/TAZ) doped with [Ir(ppy)3] was used, which led to an expanded exciton generation region [4].
Mark et al., in an investigation of the high work function transparent conducting oxide as an anode for an OLED, reported that an IZO film has higher work function (5.2eV) than a commercial ITO (4.7eV) [5].
