Numerical Estimation of Arc Plasma Thermodynamic Parameters of Electromagnetic Macroparticles Launcher

Imaging the separation of cathodic arc plasma and macroparticles in curved magnetic filters

Cathodic vacuum arc plasmas can be used to produce well adherent, dense, highquality films and coatings provided macroparticles are removed from the plasma. Both plasma and macroparticles are produced at cathode spots, and in most cases both can easily be observed because they emit light. The nature of this light emission is briefly discussed. Using open, curved solenoids as magnetic filters, o...

Optimization of Three - stage Electromagnetic Coil Launcher

For the design of three-stage electromagnetic coilgun, many parameters and their relations must be considered at the same time. However, there is no complete mathematical model to describe the relationship between these parameters and energy conversion efficiency of the coil launcher system. In this paper, using orthogonal test approach we consider the influence of 11 parameters to improve the ...

Macroparticles in films deposited by steered cathodic arc

The macroparticle content of titanium films deposited using a steered vacuum cathodic arc has been investigated. It has been found that the macroparticle number decreases with increasing steering magnetic field strength, and experimental results are found to be consistent with the model in which the number and mass of macroparticles arising from a cathode spot are proportional to the cathode sp...

investigation of effective parameters on the rigidity of light composite diaphragms (psscb) by fem

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
