                         chemical vapor deposition technique (HFCVD) diamond film as a 
                         coating on Platinum Thin Film Heat Transfer Gauges to improve 
                         their operation performance in the range of Mach 4 to Mach 15 
                         airflow, in order to acquire accurate heat transfer data in 
                         hypersonic experiments. The gauge under development has a 
                         substrate made of sintered silicon nitride (Si3N4). It has 
                         cylindrical shape, with 5 turn diameter and 15 mm length. On it's 
                         top surface there is a platinum thin film, which is the heat 
                         flux-sensing element. Diamond films were deposited at 870 K and 
                         6.5 kPa by HFCVD using a gas mixture of methane 1.0% or 1.5% vol. 
                         in hydrogen. For improving the adherence, films were grown onto 
                         Pt/Si3N4. A SiO2 interlayer was also used to minimize the 
                         dissolution of carbon into the platdinum substrate during film 
                         growth. Scanning Electron Microcopy (SEM) has evidenced a faceted 
                         polycrystalline grains with orientation (111) and (100) covering 
                         the entire surface. Raman spectroscopy has demonstrated a film 
                         with high quality and low stress, by considering the small peak 
                         shift presents in the spectrum compared to natural diamond.",
