The fast-forward video was compiled based on the images recorded during the wettability test of Si/h-BN spray 21E/SiC (on the left side) and Si/h-BN spray 401E/SiC (on the right side) couples at temperature up to 1750oC. The test was performed at Foundry Research Institute facilities by using an experimental complex that has been designed for investigations of high temperature capillarity phenomena by various testing methods (classical sessile drop, pendant drop, dispensed drop, sandwiched drop, transferred drop, drop sucking, drop pushing, drop smearing or rubbing). A more detailed description of the experimental complex is shown elsewhere: Sobczak N, Nowak R, Radziwill W, Budzioch J, Glenz A, Experimental complex for investigations of high temperature capillarity phenomena, Mater Sci Eng A 495 (2008) 43–49 The results of wettability test are described in: W.
