This paper reports on the preparation of titanium nitride (TiN) thin films on carbon steel plates, using cathodic arc evaporation CAE PVD technique. We studied and discussed the effect of various nitrogen gas flow rates on microstructural and mechanical properties of TiN-coated carbon steel plates.

To give a trial-and-error example, suppose a 20-year bond has a coupon of 8 percent, a priceof 98, and is callable in 10 years. The call price is 105. What are its yield to maturity and yield to call?Based on our earlier discussion, we know the yield to maturity is slight[r]

For some applications, the lubricants must be readily biodegradable. The tests CEC L-33-T-82 and modified STURM are two of the most widely used to measure the lubricants biodegradability. To consider a lubricant as biodegradable, for example, it must present a result higher than 67% on the CE[r]
