To evaluate the cutting performance of CVD diamond coated silicon nitride insert, two kinds of CVD diamond films, namely microcrystalline diamond (MCD) and composite diamond films, are deposited on silicon nitride (Si3N4) inserts using the hot filament chemical vapor deposition (HFCVD) method. The characterization of as-deposited diamond films is conducted using the scanning electron microscope (SEM), optical interferometric profiler, X –ray diffraction (XRD) and Raman spectrum. The turning tests for as-fabricated MCD and composite diamond coated insert, as well as uncoated silicon nitride insert, are performed in dry turning aluminum silicon alloy, where the cutting speed, feed rate and depth of cut are fixed as ν = 2000 r/min, f=0.1 mm/r and ap=1 mm. The results demonstrate that the main tool failure is the tool wear. As compared with the uncoated silicon nitride insert, the woking life time of the diamond coated insert can be increased by a factor of above 7.

Aluminum-Silicon Alloy, ADC12 is one of the most popular alloys for pressure die casting due to its high castability and high productivity. ADC12 is a hypoeutectic aluminum-silicon alloy that contains 10-12wt% of Si and has an occasional problem for a mechanical properties failure such as crack and shrinkage porosity. This study presents the investigation of the microstructure of ADC12 parts produced by pressured die casting with different process parameters and chemical compositions. The microstructure was observed using optical microscopy (OM) and scanning electron microscopy (SEM) with energy – dispersive X-ray (EDX) and electron backscatter diffraction (EBSD) to determine phases, grain, and crystallographic information in order to understand the microstructural evolution after die casting with different process conditions. Changes in casting pressure and a reduction of iron content contributed to enhanced mechanical properties and less shrinkage porosity. This was due to different processing parameters, mainly casting pressure. The average grain size of aluminum matrix was also reduced due to a higher pressure during casting with a moderately fast cooling rate.
