Computer simulation and control of plasma spraying processes

Integrated technological complex for computer simulation, experimental study and practical realization of plasma spraying processes was created. Main features of development are possibility of simulation of all plasma spraying stages (moving and heating particles in plasma jet, coating structure formation, heat transfer and strained-stress state of coating-substrate system) separately and in the mode of end-to-end; data base with material and gas properties; possibility of experimental measurement of main plasma spraying parameters and entering them in the computer in the real time mode; graphic visualization of simulation and experimental measurement results; computer control of plasma spaying equipment; fabrication of initial lots of products according to developed technology. Complex is designed on the base of VPS much less thanPlasmatechnikmuch greater than equipment. Experimental measurement of particle temperature, velocity and coating temperature were conducted with original optoelectronics system. All technological and measurement equipment are connected with computer with special interfaces and working under computer control.
