Compatibility of plasma sprayed tungsten based materials with graphite substrates

Popis výsledku v původním jazyce

The experiments showed that powders of W and ZrC mixtures can be processed by plasma spraying with WSP equipment and successfully transformed into coatings, namely on graphite substrates of various shapes. The products are slightly porous which is inherent for atmospheric plasma spray technique. Plasma spraying of a mixture of W and ZrC led to coatings with pores present predominantly inside larger particles of ZrC. This effect is probably due to incomplete melting of such particles. Due to extremely high temperatures it is necessary to have in mind the probability of creation of interlayers between substrate and coating as a consequence of chemical reactions. In our experiments these interlayers enhanced the compactness of the coating-substrate system.
