These coatings were grown on AISI 4140 steel samples. The mechanical and tribological properties of these coating is to be characterized by Adhesion Test, Scratch Test, X-Ray Diffraction Test (XRD), and Scanning Electron Microscope (SEM). Characterisitics of arc PVD-CrN coatings formed on plasma nitrided and as-received surfaces of an hardened AISI 4140 steel before and after nitiriding have been examined by adhesion and wear tests. CrN coating deposited on the nitrided surface exhibited remarkable advanced properties as compared to the CrN coating deposited on the as-received surface

Now a day number of application increases in pneumatics system due to high carrying capacity, low maintenance cost and most important not dangerous. Either compressed air or inert gas are generally used.This importance is due to its accuracy and cost. This convenience in operating the pneumatic system has made us to design and fabricate this unit as our project. This unit, as we hope that it can be operated easily with semi-skilled operators. The pneumatic press tool has an advantage of working in low pressure, that is even a pressure of 6 bar is enough for operating the unit. The pressurized airpassing through the tubes to the cylinder, forces the piston out whose power through the linkage is transmitted to the punch. This enables us to use different type punch dies resulting in a wide range ...

Sink tape embedstubes are a common procedure that offers a higher heat exchange increment and, in the meantime, just amellow weight drop punishment. This examination researches the heat exchange qualities of a flat tubein-tube heat exchanger having inner strung pipe with various pitches. Heat exchange, stream erosionattributes in a strung tube fitted with screw tape, utilizing oil as working liquid are examined tentatively.
