Multi-electrode plasma torches are becoming increasingly popular in the thermal spray community due to their good stability and high power plasma jet even when operated with inert gases. Currently the models in use feature either three cathodes and a single anode or three individual anodes connecting to a single cathode. The motivation for development of these plasma torches is based on the inh...

Metallic glass has excellent functions such as high strength and high corrosion resistance. Therefore, it is one of the most attractive materials, and various developmental research works have been conducted by many researchers. However, the metallic glass material is expensive to use, and a composite material is preferred for the industrial application. Thermal spraying method is one of potent...

A highly dense Ni59Zr20Ti16Si2Sn3 partial amorphous metallic coating, about 500mm thick, was fabricated by means of HVAF (High Velocity Air Fuel) thermal spraying. Amorphous alloy powders produced by using gas atomization were used for HVAF thermal spraying to produce an amorphous metallic coating. Microstructural investigation showed that crystallization and oxidation occurred during thermal s...

Experimental investigation of the ultimate resistance of slender, steel-plate girder web panels to combined shear-and-patch loading indicates significant interaction between shear loading and patch loading. However, an existing interaction formula is based on experimental results. Herein, an improved design procedure for slender plate girders subjected to combined shear and patch loading is pro...

The effect of Gibberellic Acid (GA3) and Benzyladenine (BA) on Aloe vera was evaluated at pot cultivation conditions. This study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. The main factor was included spraying, drip and spraying + drip. Secondary factor was included concentrations of GA3 and BA at 0, 100...

Walnut Anthracnose is among the major diseases of walnut trees in Qazvin Province which is scattered as an epidemic disease in the recent years. This research is designed to study and comparison of control methods of Anthracnose disease in walnut trees of Roodbar region. After selecting the infected garden and implementing winter and spring spraying treatments, winter spraying treatment and con...
